JUST BOUGHT A SAPPHIRE COSWORTH WITH 100'000 MILES ANY IDEA WHAT THE BEST GRADE AND MAKE OF OIL TO TO PUT IN IT ???

 

Simon at Woodford Garage has always encouraged me to use Castrol RS 10-60

 

I also use Castrol RS 10w60

 

are you gonna use it on your new engine though

silkolene rules

 

Been using Castrol RS 10w60 for 6 years in stage 3 trim, no problems at all.

I'm using Valvoline VR1 Racing 15w50 in Stage 1 but it's very expensive (about 21 Euros / Litre). I would like to try Mobil Motorsport but it's not available in Portugal anymore (since Mobil was joined to BP).

Castrol RS 10w60 is a good one, already used it, but again it's getting hard to get here (they have put it just as 10w40).

 

i use millers 10w/60

 

I prefer Castrol TWS 10W/60. This oil is special for high tuned engines. Bmw M3/M5/Z8 use this from factory.

 

THE BEST - USED IN RACING ENGINES :

Just started using silkolene pro s and have found it to be spot on.

 

castrol rs 10/60

 

silkolene pro s 10/50,found out thats the best one by far,doesnt use no shere near as much as the others.rick e

 

Silkolene Pro R 15w-50 or Motul 300V Competition 15w-50 are the best oils for you Cosworth hands down

 

Don't use 10w-60.

Use 10w-50 or 15w-50 (Silkolene PRO S or PRO R) far better quality for the same money and far more suitable than 10w-60.

Can't you use 0w 40 ??

 

0w40 is to thin!

Big chance that your cossie will use (more) oil with 0w40

 

You can but some older higher mileage engines don't like it - a bit trial and error unlike 5w-40 which is fine 99% of the time.

THANKS FOR THE HELP EVERYONE .
