Use Royal Purple brand, or AmsOil, its expensive but it easily lasts 5k miles and dyno tests show an improvment in torque and whp of 5-10 more. Not to mention the Royal Purple is actually purple (which is cool)... those two oils are actual racing grade oils. I wouldnt put it in a truck or SUV, not that it wouldnt be good for it, but your not going to notice the benifits. Its made for high preformance engines with high rpm's.
