Engine oil Castrol or FUCHS

All the local autoparts stores in my area have the proper VW approved oil oil on their shelves. I buy the Castrol that VW uses for the original fill. The weight does not matter much...you are over thinking it.

Castrol Edge 5w40 looks like the best one to get for this car.

5w40 castrol from the factory.

I only had two oil changes and stuck with the OEM Castrol 5w40 :thumbup:

Castro 10- 60 Audi uses it in R8 GT which is NA and not subject to extra thermal loaf of TC. Live in South Florida so cold starts not an issue and Sebring in August is HOT. Also run 50 % VP 103 in summer to cool things a bit and reduce prevent timing loss.

My 15 S4 has seen 3 oils in <10k miles. The factory fill was Fuchs. Dealer first change was PP Euro and my latest change the other week was with M1. I've run M1 0w40 Euro in my B5 forever and have had 0 issues with it. Saw no reason to not continue running it in the B8.

I run the OE Castrol because I still have CPO warranty for another year.

Performed the oil and filter change this morning along with a good inspection of the top and bottom of the motor. Everything looked great, nice and clean.

Dark oil is actually a good thing believe it or not. It means that the oil is doing it's job and holding all the contaminants in suspension. In fact if my oil would look clear at the oil change I'd be very concerned and most probably change the brand.

I spent ages today on the phone to numerous SEAT dealers, VW dealers, SEAT HQ, VW HQ, Castrol and Millers. The bottom line is total confusion everywhere. I rang 12 SEAT dealers - all but one (I'll come back to which one)said that VW 505.01 must be (and is)used.
