I have a 2008 Evo X with 22k miles on it. The only fluid changes I have ever done are engine oil changes every 3k-3.5k miles. What other fluid changes should be done to my car at this time? I do not take it to the dealership but to my buddies shop. Please lemme know. Thanks

 

There's a lot of **** guys here.
I only did oil changes the first 59k miles.
At 59k miles I did all the fluids and filters.
Now I'm at 79k miles.
Never had a problem!

At 59k miles I got all the boltons installed, In another 10k miles from now I'll do all the filters and fluids again.

 

I have 9k miles on mine and just had my tcase, rear diff, and tranmission done...necessary? Probably not. For at least my transmission fluid, I would say it is noticeable. Much smoother that my stock fluid.

 

I'd recommend transmission transfer case rear diff. Technically not necessary, but it's your call.

 

Motor Oil
Tranny Fluid
T-Case Fluid
Rear Diff Fluid

That's what I did on my 2011.

 

Should I go with certain type of aftermarket or performance fluids for the T-Case, rear diff, and trans fluid....My cars pushing 370whp about.

 

My preferred shop uses Redline for everything. That's what I ran/run in the 2011. No issues. My 2014 still has OEM everything except for motor oil, it's Redline.

 

+1 fanboy for redline.

 

Redline is good, AMSoil is also good. Either would be fine for you...different shops prefer different brands.

 

Sev you have three Evo's?

 

I dont have mods and use OEM fluid.
FYI - The rear differential (AYC) has 2 separate fluids. The differential side has gear oil (diaqueen) and the clutch side has ATF (SPIII ATF). The center diff only has gear oil.
For the rear diff, most people change the gear oil more often than the clutch fluid (ATF).
I'm going to change ACD and AYC (diff/gear oil side) every 10-15K, and the AYC clutch side every 20K+

 

Must be nice to have an ACD pump that works

 

Don't forget coolant and brake fluid if you haven't done those yet, too.

 

We are using Amsoil now, with great results. Motor oil after every event weekend, transmission twice and tcase and diff, once a season.
