I picked up a quart of MTL and MT-90 earlier today. I'm planning on putting in the full quart of MT-90, then however much MTL fits in with a slight overfill.

I'm also planning on mixing the MTL and MT-90. I'll probably get around to it this weekend.

My question is, if I don't autocross and only run my car from time to time, how often should I change out this fluid?

Put in 50/50 blend of MTL/MT-90 this A.M.

Was a pretty crisp day, and cold shifting was fine after 60 seconds or so. Had no problem getting 2 qts in by lifting the drivers side with a jack, putting in front and rear jackstands, and filling with a small gear oil pump in that position.

I did level out the car while draining, though, to remove as much of the old fluid as possible.

For the rear end, red-line recommended against shock-proof for a street driven car; they claimed the "gel structure" that they use to get it to cling to the gears gives it less than optimal cold weather characteristics. So I used synthetic 75W/90, Mobil one. The factory fill diff oil that came out didn't look too bad, even after 20K miles.

Lifting from the driver's side sounds like it should be easier then lifting the back of the car up to put 2 qts. in. I'll try that the next time. Thanx!

I am starting to wish I had tried a 75% MT-90 / 25% MTL mixture. I have driven about 400 miles with the new fluid, and I've noticed that the cold shifting is still great, but it doesn't really get to a "perfect" feel, like it did a week ago, or like the straight MT-90 did (fully warmed).

I still think this is a good choice for cold climates, but I will go back to straight MT-90 as soon as winter ends.

MT90 is just too sensitive to temp for me. It has to be 90+ and a warm engine for it to feel right. I am running GMSM FM and it feel distinctively better than the Honda II.

It's been 6 years since this thread was made... any new progress on blending or finding a better mix?

I think that a 75-25 Mt 90-MtL should work well exc in cold climates (Rockies or canuckistan, go MTL) I'm running GM Synchromesh Friction Modified and I love it over Honda MTF II.
