Very interesting on the wear on the oil in a motorcycle engine. I knew that the gearbox created a much harsher environment, but to loose 28% viscosity after 800 miles is a surprise!
So given that the oil looses its viscosity quite alot, do say Honda take that into account when they recommend 10w40 for the Fireblade for example? Or could one play it safe and put in say the 15w50 knowing that it will reduce its lubrication properties?
@skidlids - i think that it was your original post that i remember.
Opieoils.oc.uk have the Silkolene at a good price and only £1 delivery at the moment so i'll get some of that (along with oils for my car and bike).
Cheers
