I haven't read this entire thread, (I'm old and only have so many heartbeats left), but oil should not be a WW3 issue. Just use one that has the right numbers or letters on the bottle. Not using VW 507 spec oil in an engine where it voids the warranty not to use it seems like the height of stupidity to me. Just why?? These numbers represent very specific additive packages.
