i dont think it will be making much difference really dunc, but for whats its worth i use millers 10w60 and have done for a long time.

reading the blurb on them both and they sound identical

Both are thick as treacle!
Mind you guess it suits those agricultural engines. :lol:

will give great oil pressure and hopefully wont slop around as much as the 10/40 that i was running at snetterton and blowing out of the breathers.

Supposed to good lubrication too and well able to cope with high oil temperature. Will run at 125C without degrading.

you've been listening to the wrong 'expert'........................the only difference with a decent w40 oil is that the w60 will have far better heat abilities on track/hard use scenarios.............

Duncan would probs use the 10w60 personally

thanks Alyn - thats what I will use :thumb:

Will put the 15/60 in for middle of summer once it has warmed up a bit
