Thanks guys, very helpful info. I've always had good luck with Mobil 1 in my performance cars, but I've tried everything as well - Amsoil, Royal Purple, etc.

Thanks Dennis for the heads-up about the potential issue with the warranty and 0-30W oil, I didn't know that it might be a problem. Interesting tests results, although coming from Amsoil they do have an agenda. I really wonder how the 4-ball wear tests relates directly to engine wear and specifically what our I-5 engines are going through lugging 4600+ pounds around.

I'll be taking note of my mods and the effect on fuel consumption and report results. I'm pretty OCD about stuff like that so I'm curious what the results will be and share the info for future generations of H3 owners

 

Put aside the Amsoil producton th list..then who do you have on the top?
