hi, i have read a lot of threads, but i didnt find answer whats oils is best for(2005 USDM evo):

5speed gear box
Transfer Case
Rear Differential

ACD Operating Fluid(do i need change it?)

is the same oil in rear diff and transfer case?

at the moment i can get : Mobil 1 SHC 75W-90 LS - 17$ per liter ,or redline mt-90 - 32.5 $ per liter.

can i use same oil to feel gearbox, transfer case and rear diff?

hey I was in the same predicament went i first got my car. I'll save you the time and let you know what i use before people start bashing on you for using the "search" button.

I use diaqueen Mitsubishi fluid for the front and rear differential. I believe I used .56 L of it to fill each differential. For the transfer case, I used MT-90 from Redline Gear Oil (3 quarts) but you will get a lot of people with difference preferences. Im not saying what I use is the best but it hasnt given me any problems so far. Good luck with your findings.

yeah, i remember filling the gearbox/transfer case with the mt-90 and the front and rear diff. with diaqueen. dont know if that was confusing but if it is, feel free to pm me.

I use OEM fluids for the TC and read diff w/Redline MT-90 in the trans.

I've used Reline MT-90 on my car and I feel it is better then stock fluids. There should be a old thread about this and it would help you answer your questions.

Yes, your wording is incorrect.
