The deal is how much chemical is going to burn with just the right 'all she wrote' for that compression/heat of the day (room temp) and lets factor that all in.
Smoke is going to use who cares what weight. There is a map and there is a map. Everything else is mute once this is cleared up.
8.60 = What weight oil?
8.42 = I think Smoke's bike is close enough we need to bring oil up.
The more you heat that oil, the thicker it becomes or say in time it will turn to gunk or back to a clump of crude, correct? Are we talking one rides it to work and comes the weekend, oh I just changed my oil a week ago?
That's why this is the quick and dirty no need to change oil between rounds? Won't there be fresh oil and a chassis prep so fair is fair?
