Fluids change.... now see how it pays off.

waiting for a day off from the rain. Im gonna change all drivetrain fluids then while im at it do the rear diff breather mod. This was over $150. But gotta pay to play. I never skimp on oil quality

 

At my 10k service they checked all fluids. Then i checked my front diff and its low

 

replaced all but the trans fluid in mine so far. think the rear diff fluid change and breather mod helped quiet down the whine i was hearing. lmk if you notice any difference with the MT90, especially if you get to test in cold weather

 

I put the MT90 in mine at around 5000 miles. Things are just now getting colder where I live but I didn't notice any difference at all between the MT90 and whatever they put in it on the assembly line.

 

id really like a better oil for when its 0 outside. i especially need to look into a better clutch fluid and whether its servicable or not. i remember last winter that pedal didnt come back quickly at all!

 

Many years ago I used MT-90 in my 2004 WRX (bought new) and with under 10k miles on it. Screwed up the synchros. Not sure why since they touted being appropriate friction levels for brass synchros....not in that case. Was grinding every gear just trying to shift in traffic.

 

Mine shifts smooth even cold. It was 10 degrees when I left for work today.

Time will tell I guess.

 

I will have to change out the trans and front diff later. (Got called into work) Did get around to doing the rear diff. Cant believe with 12k it was pretty dirty and a bit of crud on the magnet
