Evening all. Owners manual ses routine oil change :
3.1 litres or 0.82 Imp gallons, your absolutely correct as
3.1 litres is .68 Imp gal. Whereas .82 Imp is 3.7 litres.
Having just done an oil change the old fashioned way I was curious why it took slightly more than advertised.
Don't want any new owners running their bikes low on the slippery stuff. Ta ta.
