    2007-8 Audi RS4 Oil specs

    Gary is correct. RLI is good oil, but it is not approved. I've not posted for quite some time. In the interval, intake valve carbon deposits has become quite a problem on all Audi, VW, and Porsche direct injected engines, necessitating intake manifold removal and cleaning of the manifolds and...

    what do you guy`s prefer mobil-1 5W-30 or 0W-30?

    In general, the 5W30 oil will be more shear-stable and have lower deposit formation than the 0W30.

    RLI Bio-Syn 0w-30 - 7,510 miles -'06 Camry 2AZ-FE

    Built_Well, if you replace Biosyn with Biosyn, the anti-wear layers will not be removed. It's the same chemistry. The only time the layers get replaced is when a new, significantly different chemistry is introduced. The high TAN number is causing no ill effects. It will come down on the next...

    RLI Bio-Syn 0w-30 - 7,510 miles -'06 Camry 2AZ-FE

    I'd suggest the RLI 5W30 instead of the 0W30 in your climate. You don't need a 0W oil in Missouri, and the 5W30 will be an oil with lower volatility and lower deposit formation. The other alternative is the 5W20, if you're willing to go to a lower viscosity oil. It takes about 2 oil changes...

    UOA + Ferrographic Analysis

    Originally Posted By: saaber1 I think Pablo said it best by saying we need to be "cautious" when using UOAs as a measure of wear. The UOA without particle analysis may catch wear or it can miss it entirely. IMO, it is probably not wise to say UOAs "always" are a measure of wear and it is not...

    Mobil 1 - Iron (Fe) Leaching - Not Wear?

    Except that M1 shows high Fe in UOA on Aluminum block/cylinder Audi engines. The only steel left in the engine are important moving parts.
