Crankcase oil

[granite]

I'm sure this topic has been done before, but I thought I would ask.

I was told that 15-40 oil is prefered for summer use and 10-30 is more for year round. I'm about to change the oil, and I'm looking for a recommendation. I'm in southern New Hampshire, and we still have another month of snow/cold weather coming. I'll probably have to run the tractor a few more times for winter clearing, but I won't be ready for another oil change until June. Any recomendations on what grade to use.

Thanks

The manual w/ my tractor (TC24) indicates that 10-30 has a range of somewhere around -10F to around 110F. Im doing these numbers from memory but I dont thnk theyre too far off. That pretty much satisfies what you'll see in SNH. In fact thats where my machine is. It came w/ 10-30 and thats what Ive replaced it w/.

-10 is not good enought for NH. I saw -18 to -22F this winter.

I would use a group 3 if you do not like synthetic's. Rotella is one. Or spend a few more $$$ and get a group 4/5. Up to you.

I run 15w-40 all year long in MA.
