I'm not trying to open the whole, "which oil is best " debate , but just making an observation. While doing my service on the weekend, air filter , plugs etc, i decided to try a different oil. I'd been using Honda HP4 semi synthetic until now, but have tried Belray 10 w 40. The difference in shifting is quite noticeable. I'm surprised. I didn't think it would make much difference to the feel of the gear changes.
