I just bought Royal Purple 20w50 Motor Oil x7, Royal Purple Max Gear 75w90, and a Mazda Oil Filter. Tell me what your experiences are using this stuff.

 

I love it. Going to be putting it in the TII engine. Rather expensive, but it's great stuff. Oil pressure seems to be a bit higher with it. Maybe 5 psi higher. Oil temp does drop with it too.

 

I premix with amsoil-but ive heard good things about idimetsu oil.
I think im gonna try it.

 

i premixed with a couple quarts of royal purple, but of course i didn't notice any difference. Only reason i used it was because i got it for free from racing beat at sevenstock last year. Good stuff from what i hear though.

 

get idimetsu oil from rotorsportsracing.com
