More or less the same as Moremazda, but different location:

83 GSL
Castrol GTX 10w-30
Redline MT-90 (Awesome, awesome, awesome)

PS In case you missed it, Redline is awesome. I just thought it would be a little smoother and protect better, but it made my car more fun to drive! Had better too at $8 a quart!

Ive been using Valvoline Durablend 10w-40 in the engine.. Amsoil Series 2000 75w-90 gear lube in the tranny and cheap Valvoline gear lube in the diff.

I plan on doing redline, cause I always hear such kind words about it but, has anyone used royal purple gear oil in their 7?

I'd rather go with purple to match my cars paint job

I run Redline for all fluids.
It is way to expensive for most people to run in the motor though...... I dont mind, worth the extra thermal protection.
