My friend just got an 2007 STi on auction and we don't have the manual.

What fluid is requiered for the engine, trany, front and rear diff? ( front diff and tranny share fluids? can't remember )

Oh and quantity will be great

Thanks!

 

5w30 for the engine (4.8 quarts)

75w90 for the tranny (4.3 quarts)

75w90 for rear diff (1.2 quarts)

 

currently I am trying a new mixture in my tranny. I am using 3 parts Redline 75w90 and 1 part Redline Lightweight Shockproof. On my rear diff I have been using Redline 75w90NS

 

thanks for the infos.
yeah some evo owner do that to, and it work great.
To bad we don't have any amsoil or redline here.

Will go Motul.

 

Motul 300V is the best I've used. Redline was fine but I feel that Motul shifts smoother.

 

I have an 07 STI too. When I switch my trans oil to mobil 1 fully synthetic made alot noise when turning. Switch to Redline noise went away.

 

I'm about to do a 30k service on my 04 STi and have all my fluids lined up.

Motul Gear300 for the trans
Motul 90PA for the rear diff
ATE Super Blue for the brakes
Amsoil XL 5w-30 for the engine
No name coolant for the cooling system
WIX oil filter

I was able to source the Motul Gear 300 at my local motorcycle shop, but had to order the 90PA from Turn in Concepts. All other fluids I can get locally.

BTW you want to get new washers/gaskets for the 2 trans drain plugs and get some thread sealant for the diff fill and drain holes. Oh yeah, you also need to get a 30mm box wrench or deep socket. My advice get a 30mm hub axle socket from Napa, it fits over the rear temp sensor w/o a problem and it is 6 point so no fear of stripping the fill bolt for the rear diff.

 

Good to know!
