5w-40 vw 502.00 only. Halving the OCI is a good idea, every engine we see whose owners do it sound better than those who don't. The only problem we've had with some VW engines is the dipstick tube is too narrow and it can't get all the oil out. If it's got a nice wide dipstick and tube then there's a good chance you'll be able to suck out successfully. If not then you're stuck with the drain plug.
