Gear oil MOTUL or RED LINE

I've used Redline 75w85 which has the Toyota spec listed on the bottle. Have also used ENEOS 75w90 without any issues.

Under hard driving conditions per the manual reduction gear oil should be changed not just inspected. Almost all off us fall under hard driving. Search around some people have gotten better range out of higher quality gear oil redline I think.

It's hard to find GL4 gear oil anymore. The only real GL4 available in the States seems to be Redline. GL5 oils are generally harsher on brass synchros. I've been using Redline since 2007, when I bought my GTI, and it shifts just as well as it did back then.

I just did my differential and tranny oil change a few months ago, did Motul Gear 300 75W90 in both.

I got the Motul 75w90 off Amazon when I did mine on my WRX.

I used redline mtlv and can’t recommend enough!!!

Redline gear oil tends to leave a thin film at all times slightly better than motul but does have a slightly longer warm up period.

I prefer Redline over Motul, but will use Motul at times because it’s cheaper.

Redline is very stiff when cold, but holds up better under harsh conditions (hard driving).

this morning i change the gear oil to MT90 redline still no luck the 1st gear crunch noise still there
