Mercedes Service, Repair and Consignment Sales Redwood City - Making Sense of Synthetic Motor Oil - Bosch European Redwood City - (650) 368-3000





Making Sense of Synthetic Lubricants

All of us have seen countless ads telling us to change our engine oil every 3000 miles. Some of us have watched the infomercials showing cars driving on the racetrack with allegedly no oil or engines running on a stand while the host pours sand and gravel over an exposed valve train. Virtually all of the lube shops have some kind of magic additive that they will say you need.

What are we to believe? Or more relevant, what is right for you? In becoming an Amsoil Synthetic Lubricants dealer in 1998 I have done a great deal of research on all kinds of lubricants and additives and in this article I will share the facts about synthetic oils, petroleum based oils, and additives so that you can make an informed decision about what is right for your cars.


1. Oil Classifications

There are two systems for oil classification. The SAE (Society of Automotive Engineers) viscosity grade and the API (American Petroleum Institute) classification that designates the type of engines for which the oil was designed. The SAE viscosity grade is known as the "W" number when classifying oils. Most oils on the shelf today are multi-viscosity such as 10W30 or 20W50. In general, the lower the first number, the better the oil will perform in extremely cold conditions. Conversely, the higher the second number the better the oil will protect at higher temperatures. If you were driving to Minnesota in the winter you would want the lowest number you could find like a 0W30. In our Florida climate however, a 10W40 or a 20W50 would be a better choice. The API designation is typically an "S" designation for gasoline engines and a "C" designation for diesel engines. Most of today's oils carry an SH,CF or SJ,CF designation signifying that they are suitable for use in all gasoline or diesel automotive applications. Those of you with diesel trucks or motor homes should look for an API CG-4 rated oil. Which brand you buy is largely a matter of preference. Consumer Reports (6/97) found very few differences between major brands of oil and all with the above SAE and API designations performed fine in normal applications.


2. Synthetic vs. Petroleum based oils

Synthetic oils were originally developed more than 50 years ago and became widely used in jet engines. Less than -120F ambient temperatures, 60000 shaft rpm, and 500+F exhaust temperatures proved too much for conventional oils. Synthetics were created specifically to withstand these harsh conditions and to date every jet engine in the world uses synthetic lubricants. Amsoil introduced the first synthetic oil for automotive use in 1972 and have continued to be at the leading edge of development ever since. Mobil 1, undoubtedly the most recognized name in synthetics, was introduced in 1976. Many companies have jumped on the bandwagon and have since released synthetic lubricants for automotive use and all are becoming increasingly popular for their superior lubricating properties, superior ability to flow at cold temperatures, and their ability to withstand high temperatures for extended periods of time. Several new cars including the Porsche 996 and the Chevrolet Corvette LT-1 are delivered with synthetic oil in the crankcase and require synthetic oil use throughout the life of the car.

There are two primary differences between synthetic oils and conventional petroleum oils. These are the base stock or liquid that makes up the volume of the oil, and the additive package. There are additives (not to be confused with over the counter additives which will be discussed later) in all oils that enhance the wear resistance properties of the oil, enhance the ability of the oil to neutralize acids and combustion by products, and provide corrosion protection for the engine's internal surfaces. The amount and quality of these additives vary from one oil brand to another and this is a very significant factor in the ability of an oil to adequately protect your engine in all driving conditions. As a general rule of thumb, the cheaper the oil, the fewer additives it has and therefore, the less able it is to protect your engine.

There is one school of thought that suggests that the only difference in synthetic oils vs. petroleum oils is that the synthetics typically have a better additive package. This statement is only partially true. Synthetics almost always do have superior additives than petroleum oils. While this does add to the cost of the oil, it also enables the oil to last 3-5 times longer than conventional oil. The synthetic base stock however, is of paramount importance in the ability of a synthetic oil to flow at cold temperatures and withstand greater amounts of heat over significantly longer periods of time. Petroleum base stock molecules are long carbon chains that are sensitive to stress and heat. Additionally, various paraffins that are contained in all petroleum products regardless of how well refined they are, cause oil to jell like a syrup at extremely cold temperatures. At the other end of the temperature spectrum, high engine temperatures and heavy loads (as typically found in towing or racetrack applications) cause these chains to break down and the base stock actually boils off causing a change of viscosity and the formulation of sludge. This can happen at temperatures as low as 230
F and by 250 F many petroleum oils are suffering significant breakdown. Synthetic oils on the other hand are engineered specifically to provide all the lubricating properties that natural oil possesses, but none of the cold thickening or hot thinning properties of petroleum oil. Synthetics are made up of uniformly shaped molecules with shorter carbon chains which are much more resistant to heat and stress. Synthetics can withstand temperatures of 300F all day long and still protect your engine. In fact the American Society of Testing Materials (ASTM) standard wear resistance tests are conducted at 302 F. In this test synthetic lubricants far out perform petroleum lubricants by factor of four to one and greater.

Oil temperatures of 230
F to 250F are not at all uncommon in driver's education track conditions, particularly in early 911s with no front coolers or the marginally effective "trombone" oil coolers. These temperatures are also fairly common in air-cooled engines in summer time stop and go traffic with the A/C on. Further, temperatures on the cylinder walls and in turbos are often over 450F for short periods of time. Liquid cooled cars can also have extremely high oil temperatures even though the water temperature may be normal. I observed this first hand several years ago in a race car where the water temperature stayed right on 210F while the oil temperature fluctuated between 240 F and as high as 280 F depending on how hard the car was driven. Needless to say, this particular car was running synthetic oil and remarkably ran about 50 hrs. between rebuilds with no significant wear.

The point of the above paragraphs is quite simply that synthetic oils have a much wider operating temperature range, by design, than petroleum oils.


3. Off The Shelf Additives  

There are countless over the counter oil additives on the market, as there have been for a number of years. In recent years a number of companies have appeared on the scene with huge national television advertising campaigns, racecar sponsorship, and more, all designed to make the consumer believe that the products really work and you are doing yourself a favor by adding these to your car. The fact is that these products are not necessary, do very little to help your engine, and in many cases may actually do more harm than good. The major car companies do not endorse any of these products and in fact your owner's manual will undoubtedly advise you to avoid them.

Consumers Reports did a test (10/98) in an attempt to verify, or rebuke, one company's ad which claimed that their product "bonded" to the engines moving parts forming a protective barrier against wear. The ad claimed that their test car ran all over Southern California, in stop and go traffic, with the air on, for 4 hours and 40 minutes. The ad also claimed that the only reason the driver stopped was to get something to eat. Pretty unbelievable. In an attempt to prove or disprove the viability of the ad, Consumer Reports tested two Chevrolet Caprices, both with identical zero time rebuilt V6 engines. Both cars were broken in with normal petroleum oil per the manufacturer's recommendations. The oil and filter were then changed with one of the cars receiving the prescribed dose of this magic additive. Both cars were then driven for about 100 miles, allegedly long enough for this magical bonding to occur, and the oil subsequently drained. Both were then driven again, now with empty crankcases, in normal traffic to see how long they would last. Interestingly both engines failed, almost simultaneously, after about 14 minutes of driving thus proving the claims of the additive manufacturer to be nonsense. Consumer Reports notified the FTC of the test and their results and the manufacturer was subsequently forced to stop running the ad.

There are some over the counter additives that contain Teflon or PTFE. Once again the ads claim that the Teflon bonds to the internal working parts of the engine forming a slippery surface (like your Teflon frying pan) and therefore reducing wear. Fundamental laws of Physics prove that such claims are impossible, as the temperatures in internal combustion engines (200
-250F) are insufficient for any bonding to occur. Further, independent oil analysis labs have observed that the suspended Teflon particles actually tend to accumulate the microscopic metals that are normal in engine oil formulating much larger, and potentially much more harmful, deposits in engines than would normally occur if straight motor oil had been used. In some cases, the oil filters became clogged, oil pressures dropped across the filter and oil analysis showed significantly more wear than oil alone. Similar to the previous situation, the FTC challenged the makers of products with PTFE on their claims of "coating of PTFE" and "reduced engine wear" based again on Consumer Reports findings of "no discernible benefits" from use of the product. The makers of these products agreed with the FTC in a settlement to stop using the above phrases in their ads.


4. Economics of Synthetics vs. Petroleum Lubricants

All of the manufacturers of synthetic oil tout the benefits of reduced wear, more horsepower, lower operating temperatures, and improved fuel mileage. All of these benefits are derivatives of better cold flow characteristics and higher levels of friction reducing additives that are found in synthetic oils. I can confirm better cold driving characteristics, increased fuel mileage of nearly 10%, noticeably lower operating temperatures, better heat dissipation capability, and long term high temperature stability based on my own experience with synthetic lubricants. Are these benefits enough, however, to persuade average drivers to give up their trusted petroleum oils and pay the extra price for synthetics? Enthusiasts, yes. Average drivers, perhaps not. However, synthetic lubricants can endure extended drain intervals, which is a major consideration toward justification of the higher costs. This benefit is not widely promoted by the major oil producers most likely because they want you to pay a premium for their synthetic oils every 3000 miles just like their regular oils. Most companies don't bother to tell you that synthetic oils are capable of going 25,000 miles or more without significant breakdown. One customer told me he drove his Toyota more than 50000 miles (with filter changes every 10000 miles) before oil analysis results told him it was time for a change. It is not uncommon for over the road truckers to go several hundred thousand miles between synthetic oil changes. The short trips and stop and go city driving that most of do is much tougher on motor oil than over the road highway driving. In fact, frequent short trips (2 miles or less) and stop and go city driving is considered by some raters as extreme and our cars need increased protection. Fortunately, we can achieve the superior protection and the economic benefits of synthetic oils while staying within the recommendations of our car manufacturers.

Consider the following economic argument. If you change your oil every 3000 miles at a quick lube center at an average price of $23.00 per change, you spend $115.00 over 15000 miles. Most synthetic oil changes cost about $50.00 (much less if you do it yourself) on which you can drive 7500 miles very safely (a 7500 mile interval is within virtually all manufacturers recommendations). Over the same 15000 miles, only two oil changes are required for an investment of $100.00. A shop could charge up to $57.50 and it is still a break-even proposition, plus you put a superior product in your car and are receiving the additional benefits that synthetic lubricants can provide. I typically drive about 12000 miles between changes with a filter change and oil analysis at 6000. Even after 12000 miles oil analysis advises that the oil is "suitable for continued use" and typically the wear metals are less than conventional oil after 3000 miles. In fact in a test performed by Popular Mechanics some years ago, oil analysis showed in New York City taxicabs that there is typically less oil breakdown and less wear metals in Amsoil 10W40 synthetic oil after 60000 miles (albeit with filter changes every 6000 miles) vs. conventional 10W40 oil after 3000 miles. As an added benefit, less waste oil is being put back into the environment. A true win-win proposition.


5.Conclusion

Most major brand name petroleum oils perform adequately provided your driving conditions are normal and provided you change the oil regularly (remember, short city trips, driver's ed track events, dusty conditions, and towing are considered extreme).

Over the counter additives have been proven to be of little to no benefit, often do more harm than good, and are a waste of money regardless of what you drive and how you drive it.

Finally, for those of you who drive your vehicle hard, tow a trailer, drive very short distances, sit idling and in stop & go traffic for long periods, live in a cold climate and/or if your car runs hot, quality synthetic motor oil, synthetic gear lube, and synthetic automatic transmission fluid is a wise investment that will provide the additional protection you require as well as last thousands of miles longer than conventional lubricants.

Mercedes Service, Repair and Consignment Sales Redwood City - Mercedes E63 AMG wagon gets 838 hp thanks to Brabus - Bosch European Redwood City - (650) 368-3000

Brabus 850 6.0 Biturbo Wagon



Generally speaking, the Mercedes-Benz E63 AMG S Wagon is no slouch. It's considerably more sporting than some full-blown sports cars, all while being able to haul the kids to soccer practice or make a quick trip to the grocery store. What if you want more, though? Well, if the E63's 577 horsepower and 590 pound-feet of torque aren't enough to sate your appetite for power, the team from Brabus is just a phone call away, and now the German tuning house has turned its hand to the E63 Wagon.

This might be the only 838-horsepower, 848-pound-foot car to be disappointing, although that's merely because 
its sedan counterpart comes to market with 850 horsepower and 1,069 lb-ft of torque. Despite these lower power figures, though, Brabus is claiming that the 850 6.0 Wagon is actually faster to 62 than the Sedan - 3.1 seconds in the long-roof and 3.5 in the four-door. Top speed is limited to 186 miles per hour.

All the extra fury is thanks to a bored-out version of the E63's 5.5-liter, biturbocharged V8. Now displacing 5.9 liters, it's been fitted with heavily revised internals and sports (naturally) larger turbochargers. Brabus tells 
Evo that the lower power output of the Wagon is all in the name of engine life, but if it's really faster to 60, we can't imagine owners will be all that bothered. We've got a fairly hefty gallery of images of this long-roof rocket up top, so scroll up and let us know what you think.

Mercedes Service, Repair and Consignment Sales Redwood City - 2015 Mercedes C-Class is no longer a baby Benz - Bosch European Redwood City - (650) 368-3000



2015 Mercedes-Benz C-Class


Once known as the "baby Benz," the Mercedes C-Class has since been undercut by the hot-selling CLA. But don't think for a minute that means Mercedes has given up on the C-Class – which is, after all, its top-selling model line. In fact, since introducing the current C-Class in 2007, Mercedes has sold nearly two and a half million of them around the world. And now it's time for a new model.

The new C-Class is not only more luxurious and more elegant than the model it replaces, it also boasts the latest safety systems. As well it should, because while the CLA is fashioned as a downsized 
CLS, the C-Class has long been styled as a smaller version of the S-Class, and that, as we all know, is one of the most technologically advanced vehicles on the market. Those systems include Attention Assist, Adaptive Brake Assist, Collision Prevention Assist Plus, Distronic Plus with Steering Assist, Brake Assist System Plus and Enhanced Active Lane Keeping Assist, as well as Active Park Assist, a 360-degree camera and Traffic Sign Assist with Wrong-Way Alert.

Among the growing array of airbags you'll find pelvis bags for front-seat occupants, a new window bag, side bags for the outer rear seats and a knee bag for the driver. Buyers will be able to choose between three all-new suspension setups (including the first air suspension in this class) and two available LED headlamp arrays over and above the standard halogen units. The climate control works with the GPS to shut the recirculation flap when entering a tunnel, and the sound system uses the body structure as a resonance chamber to amplify music.

All that is packed into a form that's both larger and lighter than the model it replaces: despite a 3-inch longer wheelbase and 1.6-inch wider form, the new sedan is 220 pounds lighter, cutting fuel consumption by 20 percent without sacrificing performance. Styling is clearly more dynamic than its rather conservative predecessor, emphasized by the longer hood and shorter overhangs, while the interior is designed to be more elegant and luxurious, with a flowing center console encompassing a 7- or 8.4-inch display, a quintet of retro air vents, touchpad controller and a head-up display.

Audi Service, Repair and Consignment Sales Redwood City - Next Audi R8 to be up to 130 pounds lighter - Bosch European Redwood City - (650) 368-3000


2014 Audi R8 V10 Plus



 

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.

Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.

There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

BMW Service, Repair and Consignment Sales Redwood City - BMW M235i Racing takes to the track - Bosch European Redwood City - (650) 368-3000



BMW M235i Racing


Last month, BMW showed off a motorsports version of its new 2 Series Coupe called the M235i Racing. While that single image was obviously a rendering or design model, BMW Motorsports has now released a video showing the real deal being tested.

From what we can tell from beneath the camouflage, the wide-body fenders ­– to accommodate a 3.5-inch track stretch – are slightly different than the image BMW previously released. Still, the body is noticeably different from the stock coupe. The video, which is 
posted below, shows glimpses of the race-prepped interior, including a full FIA roll cage, but more importantly we get to hear the 333-horsepower engine and its throaty exhaust in action.

Audi Service, Repair and Consignment Sales Redwood City - Audi already teasing, testing next R18 e-tron quattro - Bosch European Redwood City - (650) 368-3000



2014 Audi R18


You can't debate Audi's record in endurance racing. With 12 victories at the 24 Hours of Le Mans, it comes second only to Porsche in the history books of the famous endurance race – only in Audi's case, all of those victories have come in the last 14 years, losing only twice: once to its partner team Bentley in 2003 and once to rival Peugeot in 2009. It's won the FIA World Endurance Championship in both of the seasons it's run so far, and has won championships in the European and American Le Mans Series, too.

That's quite a record to defend, and defend it 
Audi will with an evolved LMP1 racer next year. Only a week after tying up its second consecutive world championship, the German outfit is already back at Sebring this weekend testing the successor to the all-conquering R18 e-tron Quattro. Unfortunately as the new United SportsCar Championship doesn't include LMP1s, the only chance we may have to see it competing here in the United States will be at the 6 Hours of the Circuit of the Americas in September.

Audi is keeping mum on the details for the time being, releasing only this one photo and promising to reveal further details before the end of the month, but we can already discern a more streamlined shape, revised aero and reprofiled headlamps among the changes from the outgoing R18. One way or another, with 
Toyota upping its game and Porsche returning to top-level competition next season, Audi may be in for its toughest challenge yet – but you can bet it won't take it lying down.

Mercedes Service, Repair and Consignment Sales Redwood City - Cop lets speeding G55 AMG driver go on Thanksgiving in exchange for revving engine - Bosch European Redwood City - (650) 368-3000






The holiday spirit is infectious, it seems, even for police officers. And, after watching this video, we're quite sure that the driver and passenger of the Mercedes-Benz G55 AMG are thankful that the Thanksgiving spirit spread long and far enough to cover a speeding ticket in exchange for a blip of the throttle.

After pulling the two men over, the unnamed police officer, who appears to be writing the ticket as he's making conversation, asks the driver what kind of car he's driving. After finding out what it is, what it's powered by and how expensive it is, he casually tells the in-car duo to slow down and drive safely... but not before opining that he's underpaid by the police force.

Now that the video is going viral (it had been on YouTube, but has since been removed by the user), we're curious as to whether or not the officer will be reprimanded for being so lenient or saying anything negative about his job. You'll have to click on over to The Mirror in the UK to see the the footage, but feel free to come back and let us know in the Comments whether you think this is just a cop being cool on Thanksgiving (that'd be our vote) or if he should have ticketed the driver.

Jaguar Service, Repair and Consignment Sales Redwood City - Jaguar XKR-S - Bosch European Redwood City - (650) 368-3000

Jaguar F-Type R Coupe
 
 
Jaguar pulled a fast one on us all when it unexpectedly shoehorned all 550 horsepower of the 5.0-liter supercharged V8 from the XKR-S into the new F-Type Coupe to supersede the existing V8 S model with the F-Type R. But that's just the beginning, according to the latest intel coming from the UK.

According to Autocar, in speaking to Jaguar design director Ian Callum during the coupe's unveiling at the LA Auto Show, the British automaker could yet offer R-S and R-S GT versions of the F-Type. Just what mechanical changes those would bring when the F-Type R already packs the company's top engine remains to be seen, but given that the same engine also powers the flagship XJR performance saloon, we could envision Jaguar developing an even more powerful version for R-S versions of the little coupe and big sedan.

The GT version, meanwhile, would likely offer more extreme aero and a lighter form for the truly performance-obsessed. Considering that the new top-of-the-line F-Type is already pushing the hundred-grand mark, you can bet any R-S and R-S GT version would approach double the base F-Type's $65k sticker price.

Land Rover Service, Repair and Consignment Sales Redwood City - Land Rover bringing diesel hybrid tech to America eventually - Bosch European Redwood City - (650) 368-3000


2015 Land Rover Range Rover Hybrid



Land Rover may have ditched its naturally aspirated 5.0-liter V8 in favor of a 3.0-liter supercharged V6 on the new Ranger Rover due to fuel economy concerns, but don't think that the British off-road brand is content to sit on its laurels with the V6/V8 strategy.

According to the TheDetroitBureau.com, the Range Rover Hybrid we showed you earlier from Frankfurtwill, after all, make the trek across the pond and into the North American market. You can read the particulars about that car by hopping over to its Frankfurt coverage page, but we'll sum it up right here - 516 pound-feet of torque and 355 system horsepower from a 3.0-liter turbodiesel V6 and an electric motor. Estimates put it at about 37 US miles per gallon, though we'd expect a combined EPA rating a bit below that.

TheDetroitBureau.com quotes Andy Goss, currently Jaguar Land Rover's US CEO and who is slated to take the company's top marketing spot, who said, "It's not a matter of 'if,' but 'when.'" Now, we've been clamoring for one of the Range Rover SDV8s sold in Europe for some time. As we won't be seeing that, this V6 diesel-electric might just be the next best thing. The only problem with Goss' statement is that it doesn't really specify when the hybridized SUVs will arrive. TheDetroitBureau.com's Paul Eisenstein does point out that the pressure is on for Land Rover, though. With federal fuel economy standards tightening up in 2016, the venerable British off-roading brand needs some fuel sippers, and fast.
