Have you guys used motul 300 75-90 in our gear boxes? Is it safe?

No, not compatible… The only two GL4 Motul compatible gear oils with the correct viscosity ranges are MotylGear 75w90 and Gearbox 80w90.

I used the Motyl 75w90 in my trans before the last swap, as well as in my LSD with an additive, since the only place around my friends neighbourhood was having a Z/G car show and was selling it for a good price while I was doing my trans/diff swap.

It was fine. Shifted nice. Clutch locked up in the diff as it should have. No metal particles in the trans oil after the last change.

Snce I had to drop that trans again, I put 1 qt of Redline MT90 and just under 1 qt of AMSOIL Manual Transaxle lube because it's all I had.

Both are strict GL-4's. AMSoil is easier to get.

This?

API: GL-4/GL-5 compatible.

ohhhh nvm. I was looking at the Gear 300 LS.

I should check my garage to see if I actually have the Gear 300. brb.

edit:

MotylGear Technosynthese 75w90 is the one I used. it's a GL-4/GL-5. I used it in the Diff and the Trans. Still got almost a full quart.

Yeah im using 300 75-90 in the subaru right now and wanted to make sure its safe for teh z. both have brass bushings. Subie gearbox is weird.

Z shifted like buttery nips but i drained out the redline and had a decent amount of shrappnel. Want to switch it up to motul because their products are awesome.

So I am guessing Motul Gear 300 is good?

if it had shrappnel, i doubt it's because of the redline. chek yer chit, bro. something might be ready to go poo.

Was normal shrap, just one very very long thin metal strand (about 2 inches long). Gearbox is solid though, everything I put to it it takes.
