Well, precisely, I think Honda describes it as lubricants from the manufacturing process being left in the crankcase that are helpful in break in, rather than old fashioned "break in oi" per se. That seems plausible. The "flush the iron filings left over from the manufacturing process" OWT, less so.

Don't see how you can go wrong following the manual to the letter.

I waited until 4000 miles to get my first oil change in my 3.7. Back when I got it Dealer said you can treat it like any regular oil change as far as miles but I decided to go ahead and do it at 4k since I had a coupon+rebate for AAA that expired. Cant beat SynBlend change for $16! Now Im on 5k intervals... only 4200 miles to go!



I change my 94 every 3000-3500 miles. But thats only cause its older and I change it myself.

Still haven't done my first on my 12 yet. OLM is down to about 25% and the truck is just shy of 6 months old. I'll get it done at right around the 6 month mark. The truck will have somewhere near 7500 miles at that point.

'break in oil'? Good heavens... Hasn't been such a thing in a looonnngggg time.

My truck has about 4500KM now and the oil life says 70%. I'm probably going to change it when it get to 50%. Just cheap insurance.

You don't trust the combination of better oils and the Intelligent Oil Life Monitor? Mine has gone as far as 10000miles on one change...

I can see why a guy with an Ecoboost especiall,y, could just default to the 5,000 mile severe service schedule. For one thing its easy to remember. If you aren't a high mileage driver its pretty convenient to grab a coupon and go to the dealer. I wouldn't do that with high dollar oil, but the regular stuff, sure. Ford is kind of cagey about this. I think I counted something like 11 different recommended change intervals if you count the ones implied by the prepaid extended maintenance plans that Ford sells. They all seem to gravitate to 5k miles, by the way.

But anyway, back on topic, super early drain of the factory fill to get the "iron filings left over from the manufacturing process" OWT is kinda dumb.
