Winter engine start up.

[Retired Wrencher 6,929]

Looking for opinions. I have a B 100 just wondering if I can use 30 weight in the winter I’ve heard people here say it works. I just wondering if I can do this without changing with the seasons. I think the bonus is with these newer engines that has the ACR as opposed to the old engines that don’t I have a 63 64 maybe a 65 10 hp that does not have ACR and I only use that in the summer. It’s not the original engine in a 1056 but it runs good. So let me know your opinion if I can get away using the 30 weight in the winter. Enjoy your day.

Absolutely. I do have one engine that I use 10W-30 in the winter. That's a 16 horse on my plow rig. Starts easier. Other than that most of our engines are straight 30 all year long.

Thanks Eric. I have propane heaters That I use to warm up the garage. I could go that way run them at a safe distance if it gets real cold sub zero type stuff...

Agree with Eric - I run 30 weight all year. Plow with a C-105 and a C-125. Let them warm up and go...

One other option for keeping the oil warm in the winter.

I use 30W in all my small engines year round with the exception of the 416-H which get 10W30.

There is no magic in straight 30 weight. The Kohler spec was written a long time ago, way before the advancement of multi viscosity oils.

Plus, there is no oil pump in these engines, it is all slung. That is the reason they recommended lighter oil in winter. It slings easier.

 

The modern day 10w-30 oils have much more to offer, and work very well in these engines. They really do change vis as the temps change. 

 

Another advantage to multi vis oil, you can use full a synthetic. These have way better heat transferring ability and being these are air cooled engines running in a dirty environment, that is a big plus. 

 

If your looking for something industrial look at the diesel oils. I do use a 5w-40 diesel oil in all my engines splash or pressure lubricated. This oil has a good additive package.

Overall they all work, I only have one 100% advice, stay away from the one brand called "lack of"
