I use shell 5w 30 in mine but some recommend 10w 40.

 

Hi

I would use a 5w-40 synthetic.

Out of those, the best ones are the Fuchs/Silkolene Pro S, Millers CFS/CFS NT, Motul Sport/300V, Red Line and Gulf Competition. The Motul 8100 X-Cess, Millers XF Longlife, Castrol Edge/Magnatec, Fuchs GT1 XTL/Supersyn, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.

Cheers

I've just put millers 10-50 cfs in my brothers wrx with ppp runs a treat 10-40 is all good too but 5-30 to thin IMO

most importantly use the genuine black filter

 

What would you recommend for a 2.1 forged block. Will be around the 500 mark. Pref something quiet if poss

 

Hi

I would probably go for a 10w-50.

They are all really good oils to pick from and any of them will be fine for it.

It's difficult to say what will keep a forged build quiet and protect properly. Yes, you can use a really thick oil to smother it and that will keep it quiet, but it won't protect properly.

Thanks.
