Hi all, I recently topped up the GS with 100ml of 10W40 car oil that has "additives"...I assume that means friction modifiers. Yeah yeah I know, forgot what I had been told. Anyway, it's 100ml out of a capacity of 2.9 litres so I was thinking it's probably OK to leave in there, but I'm riding down to PI for the supers next week and got a little bit worried about it. What's the consensus, leave it in or dump the oil and start again ? It's going to be due for a full change and new filter when I get back home anyway. Cheers, Paul.
