I know, this could/should be posted in the oil forum, but i wanted to hear from fellow yanmar owners about their thoughs experiences. I am thinking about synthetic oil in my ym2000 next change. My question is not what brand but what weight? There is synthetic 15w40 and the things like 0w40... etc. I live in sc so super cold is not an issue i just want the most protection on cold startups (say 24-35 deg. F is the coldest i would start in) but that being said in january we still can have a day that hits 70 deg. F so i want to make sure the oil can cover wide temp swings.
I also understand that the first number is the viscosity or ability to flow cold and the second is the viscosity or ability to flow when warm. If this is correct 0w40 would be my best oin on a 30 deg. day and a 100 deg. day as it would sill be 40 weight when warm but would be super good flow on startup? right?
Let me hear some thoughts.
