I'm off tomorrow and need to change the diff oil on the M3. Does anyone know anywhere in Dublin or Kildare I could pick this up tomorrow without going to the dealers?
Do I still need to buy diff oil and friction modifier or is there something I can buy now ready to use?
I used redline diff oil before and found it very good, dunno who supplies it though as I bought it online[/align]
You need Castrol syntrax 75w140 and redline friction modifier. I dunno where you can get the friction modifier. I think I got it from couture auto. The syntax you can get in any good motor factors. You add 4%, of the friction modifier to the total amount of fluid the diff takes.
So for example. 4% of 1000ml = 40ml
So 960 ml oil and 40ml modifier.
I can't remember what the diff capacity is. I think 1.1l
