Red line or if you don't put a whole lot of laps on a car JD TDH winter blend fluid--- but keep an eye on everything ---stuff works but very thin not for putting it in in March and running it for 200 laps either til November ---

I think most if the synthetic stuff is really good so there may not be a lot of difference in them.

That being said, we run redline super lightweight shockproof in the trans and rear end of our 66 Nova E stick car and Redline lightweight shockproof in our SSGT superstock stick car without any issues ever. That stuff seems clingy and super slick at the same time.

Tried some stuff that a PS team gave us once. It looked like ATF. 283 four speed stocker 2900 lbs. it literally ate the ring gear in 3 passes…

Anyone have experience with using DLC (Diamond Like Coating) on ring gears? I know that Nascar uses (or had used) that coating for durability and friction reduction. I know, not apples to apples, but just curious.
