Hi everyone,
I'm getting ready to swap my tranny and diff oils this weekend. My only concern was some people complaining about the notchiness after changing to MT-90. I know there are some users that use MTL for the tranny. Do you think there would be any benefit by getting a quart of each and mixing them together before I put them in. As long as they mix well together I don't any problem with giving it a shot. Thanks for your help.

 

I feel fine using MT90, I dunno what other ppl mean by *notchiness*, but I am ok with it. Oh, I came from the RP Maxgear boat.

 

The 90 weight IS the Mazda spec - I use the mix because I regularly drive around in minus 20* weather.

ok well I drive my car in weather no colder than 20 degrees Fahrenheit. Right now the temperature is around 70 degrees. So mixing about 3/4 Mt-90 and then 1/4 MTL would that have any benifit? I might just give it a try. A little MTL shouldn't cause any problems in high temps do you think?

 

if u never drive cold, I guess u should stay with the stock weight.

 

MTL is probably too light for you

 

Ok well I just got done changing my my fluids over to redline. When I started the car to back it off the ramps, I began to smell a very rank smell from the car. I think it is the exhaust but I'm not sure. Is this smell normal after changing transmission and differential fluids?

 

Yes, they stink, especially the diff oil. It will pass.
