Kohler 20hp in a Terramite - Synthetic?

[Chevy Guy]

I have an older Terramite T5C with a Kohler 20hp twin. I have been using it quite a bit lately and in the hot weather I was wondering if it might be a good idea to run synthetic in it? I run the engine a full throttle most of the time as its a bit underpowered.

Anyone have any thoughts? The engine runs OK and I have no issues with it, just want a little added security.

Thanks.

I assume aircooled? In Wisconsin, just run 30W.

I'm not sure of the Model of the Kohler, but the Kohlers with OHV, require 10W-30. In response to the original question, Yes you can run syn oil. My Miller TB has a twin Onan 20hp...as cheap insurance I run Amsoil 15-40 syn. Runs great. NOTE: Its an L-head engine, hence the oil weights. I have a lawn tractor with 20hp Kohler V-twin that I run 10-30 Castrol dino in...no issues after about 5 years...BobG in VA

According to the manual I have it recommends 10-30 for anything above freezing.

I run 10w - 30w synthetic in mine. May be a waste of money but I run it anyway. What do you use your terramite for? I use mine for personal use kind of a lazy mans shovel. It is a great front end loader and the backhoe works OK, not as well as a excuvator but OK once you get the hang of it. I bought a 39" grave digger bucket with no teeth for mine to clean out ditches and smooth out high spots. big dan

I'm doing some landscaping, serious fill dirt moving and leveling and some drain work/trenching. So far its been OK, just a bit underpowered. The backhoe stops as soon as a decent root or rock is hit, you can dig around it up I was expecting a bit more "raw power". I love the loader too, it works well.
