I've gone through a thread here on this splitter, and I can get it locally from Tractor Supply for a grand, sold as "County Line" brand (the same as Huskee, from what I've read - correct if wrong). I'm thinking I might just spring for one. On reading the owner's manual, for the Kohler engine it says use 5W-30 oil below 32 F or 10W-30 above 32 or 30W above 50 F. Well, no one is going to change out the oil just when the temp drops or goes up, so what would you do? I suspect I'd be using it above 32 F, even above 50, and not often below 32. I imagine, then, that the right oil would be 10W-30 as a best fit overall for my envisioned use. Thoughts?
