detergent oil??

The lawn mower is 28 years old and has always mowed a 1/4 acre, never rebuilt a diesel under 10,000 hours, the cars and trucks all went 200,000 300,000 miles. The old Farmall 300 is now on it's 6th set of pistons and sleeves. I'll bet that old tractor has 25,000 hours on it.

I'm now using the Mobil 1 synthetic 15-40 variant formulated for high mileage engines in all the tractors and lawn tractors and the old pickup. Has special goodies inside to keep old seals and gaskets from leaking. First tried a synthetic in the mid 70's. Was amazed by the lack of wear on the main and rod bearings compared to normal mineral oil for the same time on an engine. Haven't switched back.

I still have a jug of 30W non detergent around to use in the oil bath air cleaners, 'cause it's cheap. Otherwise, the stuff that goes in the engines and rear ends is synthetic and multi weight. I'm a mere kid of 57 in this discussion, but have a feeling that doesn't make much difference, as my years of really liking to do engine rebuilds to pick up speed and power are behind me -- and now the objective is to keep 'em running forever with minimal maintenance.

Sorry, my fault. A quick read said to me that it was a good place to have some fun and make a joke. Even if you had shot CNKS in the foot (figuratively) I'm sure he and everyone else would have taken it in the best sort of way in any event.

These questions about oil always bring the most outrageous and varied responses -- almost like talking about a religion -- so it's kinda fun to stir the pot.

Thanks for setting me straight. You take care, and hope you're having a good summer up there. Down here, we've had monsoons for the past month or two. Might as well have made a rice paddy as tried to plant anything this Spring.

What can I say. I have a lot of days that go exactly the same way. LOL, or laughing out loud is what they say, but when I read what you wrote, it literally was true.

You have a good one - and here's wishing that we both get through tomorrow without shootin' ourselves in the foot. If we don't get into any discussions about oil or politics or religion; we might do OK.

If it is a show tractor 10w30 will be ok for year round.
