I bought a bottle for my truck and was wondering if i could add it to the DS and my streetbike. Do you think it will cause the clutch to slip? On the bottle it says recommended for Harley davidson and other high performance engines.

Lucas oil


Thanks in advance gents.

 

I e-mailed them this weekend and the say you can. Just due not use no more than 15% of the capacity so 85% oil 15% Lucas.
