Owner reviews for gear oil

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

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

I’ve used bg synchroshift II and ravenol mtf-2. Both are great, honestly couldn’t tell much difference between them. I want to say I lean toward ravenol but the difference is minimal go with either one.

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.

Amsoil. I’m not a fan of their engine oil but their transmission and gear oil is the best I’ve used so far.

I am anal about this still so I would do it during the first oil change at 300 miles, and every 2 or 3 thousand after. Use good 75w90 full synthetic oil and DO NOT overfill the box. These gearboxes often live their lives with the oil that came in them and still outlive the rest of the scooter. But putting some good oil in there right away will get the break-in metal out, and some overkill spec oil in.

I use Amsoil on my tundra. Except for the engine oil, i use mobil just because I changed my oil every 3000 miles, and i dont tow a lot, so I'm not reving my tundra as much . It is extremely expensive. I think I spend around 400.00 for the transmission,rear diff,transfer case, etc....But I did a lot of research on them, and they are worth the money.

I just did mine today. Used VW haldex fluid for the AWD haldex, and Amsoil SevereGear 75W90 in both the front and rear bevel boxes.

i mean i guess the gear oil is ok.. i had redline and liked it a little better. i think i had MT-90 tho ..
