Motor Oil is like ice-cream at Baskin-Robbins... everyone has their favorite 'flavor'.
And, you can make a reasonable arguement both for and against almost every major brand synthetic out there.
But, if you keep the level up, change between 7.5k and 10kmi., I doubt any of these cars will suffer an oil brand related issue until long after 200k mi...
After that many miles, does it really matter what broke it?
I use Lubro-moly products and I like them. But, I also use MB1, Motul (the world's 1st full synthetic - 1948), Elf.
