what engine oil is everyone using in their cosworths?

ive been recommended a couple of different grades and am curious.

350 - 400 bhp if it makes a difference.

cheers

Fuchs Titan Pro S 10W50

 

As above Fuch is awesome oil, I would avoid 10w60.

 

Millers 10w60 cfs

 

Fuchs for me.

 

Two days ago, I asked the guys at Opie what they recommended for mine once the new engine's been run in and and they came back with this:

I would use a 5w-40 synthetic once it's been run in.

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, Fuchs GT1 XTL/Supersyn, Gulf Formula G/ULE, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.

But mine will be only running about 300bhp, so that may not hold true for a tweaked motor

 

Fuchs 10/50
Ive used this oil for about 6 years now.

 

10-50 millers nanodrive fully synthetic in mine

 

Valvoline VR-1 10W-60 works for me. About 1.0 bar of boost, and the occasional track day.
