Im just changing from motul fully to semi synthetic Ipone oil, normally mix 80:1, would i still use the same ratio for a semi oil, i know Sherco and other manufacturers all recommend certain brands of oils for there own reasons and a mix of around 60:1 in the case of Sherco but i assume all manufacturers will always air on the side of caution when it comes to giving advice.

Cheer,s

Daz

i do

It is still good oil and you can still run it at 80:1

I would not use excess oil in the mix, as it fouls the exhaust!

Thanks for the advice guys, 80:1 it is then.
