I've got all the paper work to buy Amsoil directly I just haven't made the switch. I was worried about my high oil temps and it's ability to cope.


I did put Motul in my trans and rearend

I never had any issues @ 270-290 degrees but that wasn't with the endurance car, just regular DE duties.

I'm currently running Motul in the diff and Torco MTF in the trans. Might switch to Motul in the trans next, just trying different fluids in those to see what I like most

Royal Purple makes quality stuff.....I'm bummed that didn't test Amsoil racing 15-50 as that is what I run in my racer.... In my old lemons racer we saw oil temps pegged at 300f during some overheating problems & still zero issues.....even after 16 hours on track in two days.....I test every sample through blackstone and no isssues even with overheating, since amsoil is "rated" for 150c or 318F
