Would like to know what type of oil I should use for break in oil after rebuild. Thats a engine that has new rings with Original cam and crank. I have used a 30w non detergent oil from walmart with a SA or SC rating in the past and dumped it a couple time in the first 1/2 hour than used Rotella 30w after.

Stick with the 30w Rotella or about any 15w40. That SA SC rated stuff is pure garbage and isn't fit for a worn out push mower IMO.

This would be my choice.

Penn makes all of the 30wt oil for B&S.

It's all green!

I only used that SA-SC stuff for the first 10 min of the break in, I would never use it past that.

The SA or SC garbage has almost no additives. I would just use the rotella.

bigsteve, not sure why you're using the older stuff ... and non-detergent to boot. I simply don't see the advantage.

I'd use any XW-30 mineral oil ... then dump it after 1-2 hours of runtime. Repeat this 2-3 times and I think you're good for an interval of 10 hours or more. Always check the drained oil for evidence of heavy shavings.

I would also consider using Marvel Mystery Oil (or even a little 2-cycle oil) in the gas at a treat-rate of 0.25 - 0.5 ounces per gallon. I like top cylinder lubrication when breaking in rings. Engines that I've done this for use little or no oil in moderate use. I wouldn't do this continually as I'd be afraid of fouling the combustion chamber, valves, spark plug, etc ... with many subsequent tankfuls.

Always run a HDEO like Rotella, Delo 400,Delvac 1300.Never use a SA or SB grade oil.

The Kohler engine does not have a filter so using non detergent oil keeps the junk at the bottom of the pan, at least thats what I was told and the lack of friction modifiers for breaking in the rings.

I also like using MMO in the gas.

what does HDEO stand for? I'm sure HD Heavy Duty ? Oil

Even modern engines without oil filters do not recommend non-detergent oil! Use the recommended oil. Rings and the rest of the engine will break-in just fine with a detergent oil.

bigsteve, HDEO = Heavy Duty Engine Oil. You were very close.

Yes, I suppose using a non-detergent oil may allow bits of shavings, solid byproducts, etc ... to drop out of suspension and accumulate at the bottom of the pan ... but these contaminants won't be a problem if you change the oil regularly, especially when the motor is very new. Personally, I don't want that junk accumulating in any engine of mine ... I want it OUT.

Very few engines call for non-detergent oil these days. I feel the ones that do are doing so for the many dimbulbs out there that would never think of changing oil in something small like a mower. For this lazy, short-sighted approach, non-detergent oil may keep the engine alive a bit longer ... maybe. But these neglected engines will have their lifespans shortened for sure.

In really older engines (some from the 50s and earlier) with poured-lead bearings, detergent oil may actually slowly dissolve the soft bearing material.

Otherwise, leave the non-detergent oils on the shelf.

The ND 30w oil is only used in the first 2 oil changes in the first 5-10 min of break in that its sae 30w Rotella.

Your motor will probably be fine. But I wouldn't make a practice of using a ND oil for break-in ... I just don't see the point as I don't think anything but the biggest pieces of metal will drop out of suspension in a running engine. Most of this happens when the engine sits and cools for hours.

My schedule for just about all new OPE is to run the new motor with the factory fill for 1-2 hours then dump the oil (don't do this on a full stomach).

Run it again for 2-3 hours and drain again (You'll still see a great deal of shavings, I'll bet).

3rd fill can go a bit longer ... I'd say 5-10 hours ... as the amount of metal in the oil will seriously drop off by now.

4th fill, I'd follow the most frequent schedule your owner's manual advises ... or something very close to it.

I'd give your re-ringed engine similar treatment ... maybe go an hour longer with each interval.

Best of luck.

I think we have over looked the OP's original concern about the best oil to use in a REBUILT engine.

I don't know if my tractor engine information applies to OPE engines, but here goes:

While many here say it is fine to break in a factory NEW engine with synthetic, I was taught that shop or "home" rebuilt engines are different than factory new engines. I was advised to stay away from too "slippery" oil for these break-ins. It has to do with less precise machining (cylinder hone, etc.).

I don't know about the non-detergent issue for literally a few hours.

John Deere still markets an oil labeled as break-in for use in their rebuilt engines. Maybe you can find out if it is a 30 wt..

As always, just my two cents. Here's JD's two cents:

Limited internet discussion indicates that the JD Break-in oil is 10W30:

https://webtop.deere.com/webtop/pdocshar...ets/BreakInOil.

https://webtop.deere.com/webtop/pdocshar...ootpaths=%2F%0A

I "think" it is available in quarts. Please check it out. My links appear to be bad.....but, I did find several references pointing to 10W-30....please confirm for yourself!
