**gabi_s4** · 04-20-2008 09:49 AM

so here is my question for you guys: i want to do oil, transmission, and differential fluid. and also spark plugs

for oil im pretty much set, i got 10 quarts of 0w-40.

for transmission fluid i heard redline mt90 was best, but i don't know how much of that to buy (anyone know?)

for differential fluid i haven't a clue what to get or how many bottles?

and for spark plugs i heard the bocsh ones on esctunning where good

i greatly appreciate any advice you guys have to offer. thank you

just did NGK plugs in my bro's S4 yesterday. it was rather quick....maybe 45 minutes total to change out everything. When we replaced the plugs....the car already had in NGK's. thought they were going to be bosch....but they weren't.

manual trans fluid....3.2L needed. So buy 4 bottles :)

and im gonna go with Motuls fluid instead of Redline. Its Audi approved and has better cold weather performance.
