Mobil 1 - 15W-50 Motorsport Formula, full synth
 

Has anyone used this in there cossie or otherwise?

I have it but dont know weather or not to use it?

I used that very oil in my turbocharged Vw corrado,i put it in in place of shiyte mineral oil used for running in.
My grade was 5/50 though but the oil pressure is still exellent at 2.0Bar idle(considering also the 35+degree outside temps).
I've always found Mobil 1 to be 1 of the best oils available.
No smoke and no oil consumption either.
Your Cosworth engine is very similar to the Vw twin-cam 2.0 engine so i say go for it.

I have used this in my last 2 Cossies and i reckon it's up with the best.

my rs turbo engine has it in at the moment.

It's a excellent oil, use it myself, most of the time as my fave oil is hard to get, get mine from Matt Lewis 01543 484488, 07910818110.
