I'm getting ready to change out fluid on my trans. I'm wondering what you have in yours... owners manual call for 75w-90 gl-5. I was thinking about getting a moble 1 75w-90. I've had good luck with redline products in my other cars in past. if I go with redline, should I use good'ol mtl or mt-90 or 50/50?

I know there aren't too many 5spd xj owner out there but please share your opnion.
thanks

MT 90 is what is generally used in ax-15's if your using Redling products. Thats all I have ever put in mine, I recommend it 110% to anyone with an ax-15. I have heard of some people using MTL, but 99% of people use MT 90 I believe. Dont use regular 75w-90 (i.e. mobil 1) gear oil as the manual recommends...the sulfer in it will eat away at your brass syncros over time.

I'm in ohio and it gets pretty cold in winter time. I know mt-90 is little thiker than mtl and I don't want to be all notchy when it's cold. does anybody mix it to 50/50? how about penzoil synchromesh? I had a car that required gl-3 and gl-4 because of brass synchro.

You've probably already got your answer but I'll revive this old thread anyway. I recently sent an email to Redline oil in reguards to a different car. For that vehicle they suggested mixing the MTL and MT-90. So apparently it can be done.
