Always enjoyed this guys channel. He runs caparisons on everything.
As for oils, Amsoil is the best stuff I've ran in the trans on my s13. I'll be changing my s14 to it soon. I'd love to run their oil in my engine but I can't get past the price. I run Mobil 1 in my Subaru, which I change at 5k miles because it's usually getting pretty dark at that point, Rotella T5 in my s14 because a jug fills it perfectly, it's cheap, and the car doesn't get driven too much, and I've started running vr1 in the drift car. Wix filters on all of them.
