Neither car is spec'd for it.Can you run e85? I would run something that isn't going to cost you too much (fully synthetic) and go hard on the duty cycling for a few hours then put what you want in it. e85 does a heck of a job from what we saw in testing to "clean things up" especially at high load with a normal 1-2% blow by ... Wouldn't touch it after that session though lol.
Never heard of this oil! I wonder how good it works?I agree with this but many will say Castrol Ultraclean which is not wrong either.
