Hello, Bob is the Oil Guy!
This is my first post, so please forgive me if this is in the wrong area to post.
I am on the hunt for the best (or most optimal) oil for my 2015 (B8.5) Audi S4.
I have been looking into motor oils for my car and I have found these three that seem to be good oils. I'm looking at the MOTUL SPECIFIC 505 01 502 00 5W-40, MOTUL 8100 X-CESS 5W-40, and the Penrite HPR 5 5W-40 (Full Synthetic). I believe all of these are either group three or group four oils. I think one of the Motul oils has PAO's, but I do not really understand what they are. I have a buddy who runs Lubrication Engineers' oil in his car and he said that they have a really good additive package. I haven't heard of them being used in Euro cars however. I've heard great things about Ester oils, but from what I know, they don't hold up well over longer OCI's and they are best suited for racing applications. Is there any way to know if an oil is truly "Fully Synthetic" or "100% Synthetic"? I was looking at Liqui Moly, but I've heard that Motul makes a better product. One more question, how important are the base stocks when compared to the additive package?
As far as OCI's go, I think I will change my oil every 5,000 miles. It's what I've heard to be the best for my car. I am looking into possibly modding it, so I want the best lubrication possible. I see oil as one of the most important things that I can easily do to improve the longevity and reliability of my engine.
If any of you have any ideas, advice, wisdom or anything that you think I should know as I continue my search for the optimal engine oil for my car, please reply!
Thank you very much!
Charlie
