On my Volvo oil cap, it says "Volvo recommends Castrol".
I'd *like* to think that Volvo engineers, like other auto manufacturers, recommend a certain brand of oil because they're oil experts and they've tested different brands and determined that Brand X is the best for their motor, based on how it's been designed and built, blah, blah, blah.
Sadly, I'm more cynical than that.
*I* think there's some $$$ "palm greasing" going on and that's why they recommend the brands they recommend.
Am I right, or do they really do their homework and make oil recommendations based on testing, research, etc.?
