Hello Guys
Found something strange on my B9 S4, it has a new 3.0 Turbo engine which happens to be "B-Cycle" or "Miller Cycle" and it requires a LongLife IV Full Synthetic Engine Oil (0w-20) from Castrol with is the new VAG 508 00 rating... Well due to misinformation from Audi official documents I poured 5w-40 Pennzoil Euro Ultra...
I drove it for one day and noticed about 10F less oil temperature and thats it... but since I learned you have to use the special Castrol oil I stopped using the car and am currently waiting to get a hold of that oil...
Question is should I change it or leave it? Could adding a 5w-40 weight cause any damage when a "special" 0w-20 is required?
Thanks!
