I wouldnt go for anything less than a 10w to be fair, i use (or did) 15w-50 Mobil 1 Motorsport

Always ran my FRST on Mobile 1, 15w 50, which was putting out over 170 bhp.

Guy who built the engine recommended it and I never had any problems when using it.

15/50 mobil 1 ! i've heard that silkolene pro s is a good oil !?

had put 5w 50 in the gfs old engine and it shit a cam and pretty much buggered the engine, she bought it as the halfords data list said either that or 10w40 but been told since the 5w50 is only really ok if it was a new built engine.

Run the efi engine in it now after a conversion on 10w40 so as said at least a 10w oil!!
