Got me to thinking, why is it that oil that is 100% synthetic considering king of the roost? Surely some of the semi-synthetics are plenty good, exceed mfg's specs. I am speaking about non-racing, just normal driving, which with a Camaro means an occasional burn out and hammering of the accelerator.
Anyways, I have heard all about this, still use Mobil 1 as that is what the car came with. Many say it isn't "fully synthetic" even though the containers claim they are. Whatever.
