Originally posted by zoomzoom: Why does M1 10W-30 has a higher flash point then thicker M1 0W-40? M1 10W-30 is 244 C M1 0W-40 is 230 C I assume higher flash point means less deposits right?

Originally posted by zoomzoom: Motorbike I belive that result was a fluke..There is no way 0W-40 would have higher flash point then their 15W-50?
