Fuchs Silkolene Oil

Concerning engine oil we trust in products of Fuchs. Our recommendation is semi-synthetic oil Comp 4 with viscosity 10W/40. As a more favorable alternative we also offer a mineralic oil with synthetic components (Super 4) with the same viscosity.We don't recommende expensive race oil with viscosity of 5W- for he XJR causing clutch problems. The engine is set up for mineralic oil, even Yamaha recommends it too, therefore nobody has to be worried that this oil is not adequate. It's qualified for tough driving.
