Where do I buy break-in oil?

The additive package in breakin-oil helps seat fresh rings better than regular oil. Regular oil has a higher chance of scuffing the cylinder walls during break-in. I don't want to start a war but "without incident" doesn't say much. You couldn't possibly know that without pulling the head after break-in of each engine and inspecting cylinder walls and rings. An engine can run seemingly healthy for thousands of hours before some types of wear really become noticeable, and by that time it can be pretty near impossible to trace it back to break-in.

I know very well you can break in an engine on regular oil, I've done it too, but I do believe break-in oil does a better job of setting up rings and cylinder walls for the long haul. An engine broken in on regular oil might go 10,000hrs before blow-by or oil consumption is diagnosed as "excessive" or some other noticeable failure, whereas an engine broken in with break-in oil might go 15,000hrs. By that time, you'll probably never hear of the failure anyway. It's up to you if the probable extra life deems break-in oil a "requirement". To me, it does.

The chances of a customer servicing an engine well enough to get 10,000 hours on it here is slim and none. I get what you're saying, but 98% of the population will never see the difference, and as you say, it can't be traced back at that point anyway.

So, your argument for break in oil to get to 10,000 hours is splitting hairs, just like mine is generalizing as to argue for not using it.

Bottom line...10,000 hours on a pickup is over 400K miles...how many people ever see that? 10,000 hours on a big truck is common, and I'd argue how many of those had break in oil used? 10,000 hours on equipment is relative depending on where you are...guys around here put a couple hundred hours a year on things, so 30 years it might get 10,000...other areas it's 3 or 4 years to get 10,000...
My point being, in most applications, if you get 10,000 hours out of an engine, you did fine. Major it and go again...


I'll keep not using break in oil, but you already knew that.

For the sake of conversation, what actually changes between conventional oil additives and break-in oil additives?

I don't get in to the break-in oil kool-aid, but mostly because no-one will answer my questions.

Things like paraphine content and oil shear come to mind.

Haha yeah, I know I won't change your mind ? that's ok. I just always get irritated when I hear of good guys/shops cutting corners on the easy stuff 'cause "it lasts long enough no-one will notice". Makes me wonder what other corners are being cut. I mean, seriously, you could rebuild an engine, do no head work, guess at the valve lash and break it in with the old oil and filter and chances are you'll still never hear of the failure, or it'll be blamed on something else. Although I do see your point, I don't see it as being justification to say break-in oil isn't necessary.


If 10,000hrs is life expectancy on the stuff you work with, then I can see why my numbers must seem exaggerated.

I can promise you I don't cut corners on engine builds, I spend more than any other local shop does on them, and I actually do more than buy reman engines and put them in. I won't touch an engine unless the block comes out of the frame, everything is tanked, checked for cracks, cranks and cams polished, head done, the whole works. I will re-use a customers injection pump and turbo if they prefer (as long as both are in good working order), as those parts are easy repairs later.

However, you can't prove to me any better than I can prove to you that break in oil absolutely does, or doesn't work. If you do have proof, share it. My bet, is it's the same reason that John Deere still pushes break in oil...Marketing, and profit margin. If my OEM doesn't recommend it, nor has any other OEM we have dealt with on 40 years, then again, we're splitting hairs on it's actually real world advantage.

So does anybody know somebody that has the Driven, or any other, 15w-40 break-in oil in stock?

Jegs and Summit are both backordered, and the Driven distributors in my area all tell me they'll call me back but then don't. I'm looking for this stuff next week sometime...
