PP 0w20 or QSUD?

just curious, how many miles are your intervals?

I'd be happy to use either.
I have the QSUD precursor, QTP, in the old E350 ATM.
I've used lots of both PP and Q syn and have no systematic preference for either.
Use whichever you can get a better price on.
I think the two oils are very similar in any event with not much to choose between them other than price.

Why did you have to replace the valve cover at 88,000 miles?
