2008A6

I have to top off my 2008 3.2 between changes as well. I think it depends on how and where you drive. I tend to be a bit more aggressive with the gas pedal than average, so i have accepted more oil consumption as normal..

A bit of oil consumption is normal, especially with a heavy foot.

I've not seen my oil light come on in 45k miles of driving an '06 A6 3.2 - but it has been serviced at exactly the factory recommended intervals.

If you push the service interval out, I can imaging the light coming on.

Thanks so much to all for the feedback.-Its good to have a support Group.

The OIl interval is every 10k oil & Filter change.-The Oil recommended by the Manufacturer MOTUL,PENTOSIN and a few others.I read that the cars come fron Germany with 0w-30 weight.I have been using 5w-30-MOBIL-1 to top it off when the light comes on.Then the light sensor automatically turns OFF.

On my next oil change,I will be using 5W-30 ROYAL PURPLE.The oil meets and exceeds all OEM,even ECS Tuning is now selling it.The price per Quart,for this Synthetic Oil, is around $8.40 per.

RP’s Unique Performance Advantages

Advanced Technology Creates Advanced Products

Royal Purple’s advanced additive technologies, such as Synerlec, enable its products to outperform leading synthetic and conventional lubricants. These unique chemistries strengthen the base oil for improved performance. They also create an ionic bond that adheres to metal parts for continuous protection.

High Film Strength Improves Performance

The film strength of a lubricant is its inherent ability to withstand the effects of load, speed and temperature without breaking down or rupturing, thus enabling the lubricant to maintain an unbroken film between lubricated surfaces under operating conditions. Royal Purple’s high film strength improves combustion to free up more power, optimize fuel economy and reduce emissions. High film strength also dramatically reduces wear.

According to the editors of Hot Rod Magazine, "We’ve torn down some of our dyno engines that have been seriously abused, but with Royal P(urple) in the pan, the bearings have looked new."

This debate is as old as the hills. And Royal Purple has been discussed many times on the Porsche forums I frequent. And people much smarter than me when it comes to oil agree that Royal Purple is basically snake oil.

Ernestolopez, it doesn't matter what you put in into the engine. If the engine is starting to burn engine oil, it will.

I have just put half a litre in again today, the second time in under 4 weeks!
Not sure how many miles I have done this month but no more than 3000 I would guess, probably closer to 2000.

I know that the guys on the Alpina forum had this problem with their Alpina B5s using a litre every one to two thousand miles, swapping over to a 0w30 to a 10w60 meat that they could go the the whole 12k miles without adding any, or maybe half a litre.

However, you need to make sure you are not going to experience temperatures etc. where this may cause problems.

My other car is an M3 and that uses 10w60 as standard and it never needs oil between servicing, and that is a proper performance car as well, so it is a little annoying and I may ask Audi about changing to get round this, as I never see below 0ºc or above 35ºc in the UK.

Sorry Ernesto, skip the Royal Purple. This is not my research, but BP's.

Truth in Advertising: BP v. Royal Purple
By George Gill

Royal Purple Ltd. was black and blue after BP Lubricants USA took it to task over advertising claims for its synthetic motor oil, finding a receptive audience in the advertising industry’s self-regulatory forum.

The National Advertising Division of the Council of Better Business Bureaus recommended Porter, Texas-based Royal Purple modify or discontinue numerous advertising claims for its synthetic motor oil, following a challenge by Wayne, N.J.-based BP Lubricants. The NAD examined comparative performance and superiority claims in print, broadcast and Internet advertising. In some of the advertising, Royal Purple compared its performance to Castrol, Shell, Amsoil and other motor oil brands.

NAD recommended that Royal Purple discontinue its use of consumer testimonials reporting specific performance attributes in the absence of reliable independent evidence showing performance capability.

“Anecdotal evidence based solely on the experiences of individual consumers is insufficient to support product efficacy claims, including claims related to horsepower, torque, fuel economy or engine heat,” the organization stated. “While the advertiser may quote from published articles if it provides clear and conspicuous attribution to the publisher, it may not rely on such articles to support efficacy claims for which it has no reliable independent validation.”

NAD recommended Royal Purple discontinue claims such as “Increases horsepower and torque by as much as 3 percent,” “Reduces Engine Wear by 80 percent,” “Superior Oxidation Stability” and “Provides Film Strength Up to 400 Percent.”

“If industry-standard tests or tests with carefully documented controls were abandoned, there would be no basis whatsoever for making any meaningful claims about the relative efficacy of motor oils,” BP said in its challenge.

NAD recommended that Royal Purple discontinue claims that stated, “Improves fuel economy by as much as 5 percent” and “Fuel economy improvement up to 5 percent or more” because its Environmental Protection Agency testing was inconclusive and the “Oklahoma State Study” and single cylinder Labeco CLR diesel engine testing cited in Royal Purple’s advertising was not relevant. The NAD noted the 1997 OSU Study was “outdated and nothing in the record demonstrated that the formulations of the competitors’ oils were similar to those available for sale on the market today.”

BP Lubricants said it hired the independent laboratory Southwest Research Institute, in San Antonio, to analyze power output of gasoline engines with Royal Purple Oil and with BP’s Castrol oil for comparisons. “The results were provided to the challenger’s expert statistician who was not informed of the identity of the candidate oils,” NAD stated. “The challenger’s [BP’s] expert determined a 0.9 percent difference in power between the oils, which did not rise to the level of statistical significance, and is well below the 3 percent claim made by the advertiser.”

SwRI did additional tests to independently determine the differences in fuel economy, emissions data and engine temperature between Royal Purple and Castrol motor oils. According to SwRI, “there was no statistically significant difference between the fuel economy, emissions data or engine temperature between the two candidate oils,” NAD said.

Following its review of the non-anecdotal evidence in the record, NAD recommended that Royal Purple discontinue the claims, “Reduces emissions up to 20 percent or more” and “Reductions in emissions of 20 percent or more” because the studies on which the claims were based were outdated and not consumer-relevant.

NAD also recommended the advertiser discontinue its unsupported claim that Royal purple motor oil is “API/ILSAC Certified.” Noting that API and ILSAC licenses and certifications have many categories with different meanings, the NAD recommended that the company discontinue its claim that its synthetic oils are “generally ‘API/ILSAC Certified.’”

In fact, no Royal Purple products are certified to current ILSAC specifications.

The American Petroleum Institute licenses its trademarked Service Symbol, or ‘donut,’ for display on qualified engine oils, and also licenses the ILSAC ‘starburst’ logo for oils that meet the auto industry’s latest energy-conserving standards. In API’s online directory of licensees for its Engine Oil Licensing and Certification Program, Royal Purple has a total of 23 passenger car and diesel engine oil products listed, all licensed to use the API donut. Five of these may additionally display the words ‘energy conserving’ within the donut logo, but none of the Royal Purple products are licensable to the current ILSAC GF-4 specification and they cannot display the starburst logo.

Royal Purple also voluntarily agreed to discontinue the claims, “most advanced,” “unsurpassed performance” and “unparalleled performance,” steps the NAD said were necessary and proper to avoid confusion in the marketplace.

“While Royal Purple also believes that the tests and testimonials it supplied as evidence accurately portray the benefits of using its synthetic oil in a wide variety of applications, it defers to the NAD’s position that those tests and testimonials alone are insufficient to support specific performance attribute claims in consumer advertising,” the company said in its response to NAD. “... [Royal Purple] has already made changes to its advertising in accordance with the NAD recommendations and will continue to implement NAD’s recommendations and analysis in developing Royal Purple’s future advertising.”

BP Lubricants did not return phone calls from Lube Report requesting comment on NAD’s decision.
