Royal Purple Max Gear baby!!!

 

Use a 75W90 full synthetic.

 

I use mobile 1 75w-90 synthetic havent had any problems yet.

 

what do you think about this stuff, and have you ever run any other oils like the redline so you could compare. Just found out that the local parts shop carrys royal purple, and I was thinking about going to that if it is worth it, and I do need to change the tranny fluid, being that I have no idea when it was changed last.

 

I"m going to change mine out with redline mt90

 

Does anyone have any direct comparison between any of the 75W90 synthetics with usefull results? I really doubt anyone has any usefull first hand experience that would point from one to another that could go beyond any possible placebo effects.
