Since I have never verified the actual oil temperature on my small air cooled engines I thought it would be a good day to try it and see whether there is any substance to the idea of air-cooled engine oil running hotter than liquid cooled engines. It is 71 degrees here today and I measured the oil temp on my Jeep Cherokee engine after a 10 mile drive on the highway. It was running at 152 degrees F. I had some mowing to do which I used a wheel horse tractor with Onan p220g 20 horsepower engine. After 20 minutes of mowing the oil filter external temperature was 204 degrees F. Since it is a very mild day here I have seen enough evidence to be convinced that air cooled engine oil run significantly hotter than liquid cooled engines operated in the same environment. That is reason enough for me to run a different engine oil in my air cooled engines compared to liquid cooled. Everyone is going to have a different judgment on this but I believe it is worthwhile to make sure that your air-cooled engine oil is not running too hot which is going too shorten the lifespan of the engine.

As I mentioned, it is so common that I have yet to buy a tractor that did not have JB Weld used somewhere. It is sometimes used so well you can't tell its there and other times used as a sloppy quick fix. Finding where and how it can be used correctly is key to whether you are using it as an "inelegant hack" or an integral solution to difficult and expens
