Oil
« on: February 21, 2022, 05:06:24 PM »
Local motor factor here has stock of 15w-40 mineral oil but no 10w-40. Considering that this would allow me to use in - 15c instead of - 20c I can’t see that would be a problem. I know this subject had been flogged to death, but my question is any problem with using 15w-40 in these classic Honda’s? If it is negative anything outside I don’t think I will be jumping on the bike.

15w-40 is fine. I use it in all my bikes.

The original Shell Rotella back in the mid seventies certainly was good in terms of detergent content is that why diesel spec oil would be better Bryan?

I believe it also has something to do with anti foaming with diesels having turbos and we have wet clutches and gears  :D

Additives that are no longer in petrol oils that are better for gearbox.
Running the oil in the box destroys the oil quicker
