Added quart of wrong kind of oil
Sigh, I feel stupid. Went and put in a quart of oils as my 2012 S4 was low. It is Mobil 1 5W40 synthetic. That would be okay, but I looked after and forgot to check if it was a blend that conforms to Audi standard 501.002 or something like tgat. Nth is just says it conforms to Mercedes' standard so I suspect it is not the right blend for the Audi. I have not driven the car yet, and I guess I could just take it for an oil change (another 500-5500 miles to next maintenance interval). So what should I do? Feeling stupid....
Thx for any info.
