No need to bandwagon and bash RP. It is likely just as good as other HM synthetics. It's only down fall is price. Buy at pepboys and use their 30% off codes and get free shipping to boot and it can be had reasonable.
OP just stick with HMX RP if you have been happy with it. HMX contains synerlec and a robust zinc/phos additive in it. It's good oil.
I too love Amsoil. I agree they should offer a high mileage oil as well.
