They can and they do say you have to use the product and it's legal to do so as long as you or your independent mechanic have access to it.
It's not exclusive specification that's the problem, it would be exclusive availability. The latter is a restraint of trade. The former isn't. I suspect the price should be reasonable and it is.
It's simply ridiculous to think somebody is getting away with a legal violation.
Don't think there's any guarantee that Castrol Syntrax from Europe is same as Castrol Syntrax from PepBoys. I imagine the PepBoys bottles indicate "made in USA" and that that means it's not the same. This is an exclusive formula for BMW (and formerly Land Rover during the BMW ownership era) and I suspect you could check at a BMW car dealer, where the mantra is still "lifetime." At the BMW car dealer there are two versions, i.e. limited slip and not. A formula exclusively for BMW does not fit the usual PepBoys marketing strategy. Syntrax is simply a trademark registered by Castrol and that registration does not obligate them to put the same stuff in every bottle with that label.
And it would be interesting to see how they would explain in court how Mobil 1 caused a final drive failure.
