Amsoil is much better and lasts much longer and will come out to save a lot more money than using RP.
RP is great for people who rebuild their engines on a regular basis, like funny cars and stuff. But for most of us who use our cars to go back and forth to work, Amsoil is the way to go. It's the most cost-effective oil and there's not another oil on the market more convenient to use. They back up their oil with a written warranty. If anything happens from the results of their oil, they will pay to fix your engine. I don't see any other oil companies offering to do that.
