Flushing Oil vs Kerosene?

[Lylat1an]

The manual for my tractor says to flush the crankcase when changing the oil, and to use kerosene or flushing oil to do so.

Which is better, and how much should I use?

 

[Stephen Newell]

I used to do that and was told not to. Said running the engine for a few seconds with kerosene was putting more wear on the engine than the cleaning was helping. Have been adding engine flush to the oil before changing the oil ever since.

Thanks!

I would do neither!

Sounds like a holdover from the nondetergent oil days.

Just use detergent oil and change it regularly.

well the thing is all the sediment is in the bottom of oil pan . pan should be removed to clean it. but yes kerosene was recommended in about
the 1950's. also just start and stop engine to flush gallery's. was not a fan of that. todays oils no need for that.

Just to add to what the other guys have
said, be sure to drain the oil when the
engine is warm

I buy and use plain Mineral Spirits for multiple uses including cleaning parts and systems -it will not harm internal engine components nor hydraulic systems, and it is the MAIN ingredient (92-98% typical) they use it in all the snake oil products made and sold today like MMO,STABIL, SEA FOAM,PROLONG, to name only a few of the many. Many fellas use a 50/50 mix of Acetone and UTF or plain diesel fuel, both work well too. For any product you can do your own homework by searching keywords MSDS ---- then insert the product name. You will get the Material Safety and Data Sheet listing the product with all ingredients and the safety hazards involved. If the product lists no ingredients and states that product contains proprietary information they are lying so be very skeptical. MMO was like that for years. there is NO mystery involved at all with that product. I don't use any of those products anyway. Of course some may clean and dissolve grease, oil;, and dirt because that is what Mineral Spirits does best. Oh, and FWIW & FYI, Mineral Spirits is the exact 100% ingredient in plain old Charcoal Lighter Fluid and plain old Paint Thinner.

If you drain the night before and let drain till morning then put new filter and oil in it will do as much as all the snake oils and patent medicines will. That's all I do with engines running a million miles and more.

Question , is this motor equipped with filter or without filter.

It's a John Deere H: It has an oil filter, and a "screen" around the oil pump.

I use diesel for things like that. Works as well a Kerosene but much cheaper.
