im looking into doing a full fluid flush for engine/trans/rear/Tcase
what fluids do you prefer and why? OEM / aftermarket?

 

how many quarts of transmission fluid do i need?

 

search, homie. this has been covered plenty of times!

-Jalal

 

Engine: Motul 300v 10W40
Gearbox: Motul FF LSD or Redline MT90
Transfer: Redline Heavyweight Shockproof
Rear diff: Valvoline LSX

This is on Early Evo I - III stuff though.

 

Fluids? Great topic. We never talk about this.

 

me = amsoil for everything

 

engine - mobil 1 10w-30
trans - pennzoil synchromesh
tcase/diff - diaqueen lsd gear oil

but you really need to search lol mucho information on here

 

You will find lots of opinions on here on which oils and fluids to use. This thread will likely end up into a pissing match between oem, mobile 1, and amsoil.

I personally recommend 'aftermarket' oils, and leave it at that. Tons of info on here using the search feature. Why do I recommend aftermarket and NOT oem? Well thats just from personal experience.

Without throwing different brands around I will say that the type of fluids you use in your drivetrain can effect your mpg. Depending on what type of driving you do and climate, a 90w fluid will give you better mpg than a 140, for example, but might not be best for track duty. Something to consider.

 

thanks guys, and yea i tried a search before but its hard to find exactly what im looking for when everything that pops up is either vendors/forsale/build threads or just random 50 page threads on nothing that have "Fluid" highlighted

 

^^^^ use advanced search, search by threads not posts, you can also select what section you want to search in, i.e. X, 1-9, etc.
