Why should I trust the warranty of a company that doesn't have mfg approvals because they're too cheap/worried to test it over the mfg warranty of the ones who make the car?
Why should I even use an oil that claims to be OK for, oh say, a M54 engine, when I can use an oil that I *know* works with said engine.
And avoid any cat fights between the oil maker and the engine maker?
All ready had a troll on BITOG claim that using dino oil in said engine would work. Was so sure that it would that instead of putting his money where his mouth is, he looked for volunteers.
Just like the trolls here............
Find that A3/B3 dino oil yet Mr Trol......er Kirk? You remember? You asked a stupid, trollish question as to why I don't use it? And I had to educate you on 1998+ bimmers? Not "beamers".
