I have a CA, WD, and D15. As I clean and fix them I switch the engine oil to synthetic 15w-40. I put HyTrans in everything else.
But...Got a parts cleaner and cleaning the oil bath filters. I know the manual advises using the same single weight oil as you are using in the engine. What is a more modern take?

Any advantage to using the good synthetic?

Any issues with using HyTrans?

Am I missing an option? For example using bar oil from my chainsaw.

I know, I've witnessed people using used oil. I don't mind the extra dollar spent on using the good oil in the oil bath.

My question goes more into functionality and performance of the oil bath filter.

The manual states that the oil in the engine and oil bath filter needs to be changed to the weight predicated by the current temperature. Specifically engine oil should be changed every time the temp changes.

Many of us know that modern can oil perform in more than one temp range, doesn't thermally breakdown, and that 10K to 20K miles between oil changes is now the norm.

So maybe easy answer is to put new multi-weight synthetic in air bath and change once a year.

Happy to hear any input.

Years ago the operator's manual said to use drained engine oil. so most anything would be OK. I never used it though. When I had oil bath cleaners I just used new engine oil.

Still use the same oil in the air cleaner as in the engine. I also use 15W/40 in my old gas tractors as that's what I have for my diesels.

Today's Featured Article - Tractors and Winter - by Staff. Unfortunately, tractors and winter don't mix well. It seems that I can start out with my tractors in great running condition but sometime during the long cold dark winter they quickly revert to the lawn-art category. The lack of running, cold weather, and admitted neglect all take their toll on a machine. If you are lucky enough to not need your tractors during the winter months you can perform a few simple maintenance items to winterize and come spring have them going by reversing the process. If you need your tractor in ready-to-run condition (like that ... [Read Article]
