Engine break-in oil

[JP D17]

I overhauled my D17 (gas). I put in 30wt non-detergent oil for break-in purposes. My question is how many hours should I run it before draining and putting in normal
Oil?
Thanks you

I'm surprised you were even able to find any non-detergent oil !! I dunno. I never used any break-in oil in the 50+ years I've overhauled those gas engines. Which age engine is it ?? full flow oiling system that used a Fram PH8A style filter?? Or the old bypass cotton string filter like a WC and WD use ??

It took a bit of hunting around to find the non-detergent oil. Here are pics of the oil, the filter, and the old style filter mount on the side of the engine. Other than the oil itself, the other two pics are of the filter & mount during the disassembly process.

I’m pretty sure it is a 1959, series 1.

FWIW that is a detergent oil you are using and a detergent oil is the correct oil to use in a pressure lubricated filtered or bypassed filtered system.

JLMac - you’re right … I forgot that while I was out looking for a non-detergent oil for break-in that I came across this oil and decided on it for the higher level of zinc properties. Thanks for helping get re-aligned .

Any guidance on how many hrs to run this as a break-in oil?

You are correct. It is an early 1959 model. I guess I'd probably not run it more than 50 hrs or so, with the old filtering system. Not knowing how you intend to use the tractor, or where you live, I'd be thinking a good 10W-30 type oil to use, likely year around, instead of a straight 30 weight.

I change oil after 15-30 minutes after initial start up .
Doesn't seem to hurt anything so far. Makes the pocket book squeel in pain.

Oil is part of the break-in. How are you going to load it to seat the rings? Dyno, heavy work?

Having not overhauled one of these before, I much appreciate all your insights & advice. The PennGrade oil is supposed to be good stuff; glad I stumbled across it.
It is an Iowa tractor. I’m going to work it / beak-in by mowing pasture.
