| I'm actually running rock oil, but I think that the merits of a lower grade are worth exploring, the trouble with the treacle is that most of it will have run off back to the sump whilst the bike is hot.
I'd be interested to try the Shell 15/50 but it’s impossible to get hold of.
Anyone had experience of Mobile 1 leaving a sludgy type substance in the engine when the engine is stripped down? And why does it get dirty looking so quick? |
