Synthetic scepticism

What if Mobil et al gave Porsche, BMW etc a massive rebate on the oil they
purchased to put in their new engines as they came off the line. Dont you lot
of healthy sceptics think that for a tiny moment, that the Mobils of this world
would get an endorsement for their product, if the engine users were happy that
with this juice they would at least have engines that would deliver for the
warranty period plus say 50%?

I think it naive to believe that just because any manufacturer says that they
include a product as useable, that it is automaticly a preferred and better
performer.
