Oil & Fuel What Synthetic oil should i use

[clemsonfor]

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.

I'm not to far from you with pretty much the same climate.In my 2000 I use Castrol 15w 40 Diesel and change it every 50 hrs or the end of the summer when it sits and doesn't get used as much. I also change my oil filter every oil change.Believe it or not known some who don't.That reminds me it's about that time again and go see what all I have and if I need to give Hoye a call.

... I also change my oil filter every oil change. Believe it or not known some who don't.

...People who follow the Operator Manual! It says change the oil at 100 hour intervals and replace the oil filter at each second oil change.

(But I change them with every oil change anyway.)

It also says to drop the pan and clean the oil pump intake strainer at 600 hour intervals. I wonder how many do that?

i had seen the synthetic rotella at TSC of $29/ gal. Is that what you use? It is still 14w40 so would it flow better cold than dino 15w40? It dosent make much sense as they are identical viscosity?
