The 2009 Corvette ZR1 is rated at 638-hp. As long as an oil meets GM4718M that's all this machine needs for proper lubrication. Since the 1/4 mile wails by in 11.2 seconds at 130.5 mph,* an oil good enough for this thing should be good enough for almost any thing. Not necessarily but you get my drift.
Why do vehicles like Porsche, Ferrari and BMW M's specify heavier oils than this Corvette? Is it just the European mindset vs the American mindset? Or are engines in European vehicles actually manufactured in some way that requires the thicker oils protection? I mean 10W-60 and 5W-30 are pretty different. Aren't they?
I think a BMW M5 and a Corvette ZR1 have more in common than a Toyota Camry and a ZR1 do with each other. At least I think it is normal to come to that conclusion.
Why are European specs like:
- MB 229.1, 229.3, 229.5; BMW LL–01
- VW 502.00/505.00/503.01
inconsistent with American/Japanese specs like:
- GM 6094M, GM 4718M
- Honda HTO-06
Is it just a preference for Long Life, thicker oils that distinguishes European from American requirements?
Does it have anything at all to do with PAO content?
