What Kind of oil to use

Sure wish I had a log splitter.

I would stay with the Non-Detergent oil . Case being not the clean engine trouble. But first was the tractor rebuild? If it was use what ever oil you wish to.

Now , The guides in the heads on these older tractors were made for oil to go past them, if things are seated and you put deterent oil and clean them off , now she is going to smoke if she was not smoking before. About the rings and cyclinders I was always told same thing here.

I would say the deterent oils would clean some of the build up out , But in ours tractor 2 H's and 5 AC's I will use Non-deterent , Most are 50 + years on the engines That old oil must be doing something ??? Change oil when you should and filters and she run for years.

I agree with Dave, NC and Sammy, use a modern oil. If this engine hasn't been overhauled and cleaned however I might error on the side of caution and change the oil frequently for the first while.

The arguement that always arose about the detergent vs nondetergent oil is that the detergent oil may cause old sludge and solids to become suspended and cause damage. That's what the detergent oil does, it holds solids and sludge suspended in the oil so that the filter can catch it and also so that you get rid of the solids and sludge when you drain the oil. The old non detergents would allow those solids to settle out and create deposits.

If you have lots of time and want to tinker with the tractor some I would suggest that you drop the oil pan and clean it so that at least you have a clean resevior.

That's my 2 cents anyway.
