At what mileage was your truck "broken in?"

The break in is around 300 miles . After that your truck learns how you drive .

 

I don't believe the ECU learns driving habits. Pretty sure it's only responsible for making micro-corrections based on driving conditions and all sensor inputs. I could be wrong though. I think the TCM is where all the learning happens which neither you nor I have.

 

42xxx on my 19, I'd say right now is the best it's ever been, averaging 19.5mpg. I'd say it was broken in at like 20k as far as consistency goes though

 

Mine was already done when I bought it, I didn't need to do anything.

 

Mine learned my habits after 1500 miles.

 

I'm at 33k, still feels new. I'm guessing 90k it'll be broken in.

 

Same as i've noticed for mpg...except the truck seems to have more giddy up.

 

Huh ... Mine has yet to use any oil at all...
I've got 8800 miles ... Granted, I did change my own oil/filter @ 2K miles (Old habits die hard, and I slept better .. LOL) but between 2K miles and close to 9K miles, I haven't used any oil. And I have the 2.7, so maybe a difference between the 4/6 cyl ? IDK..

 

Ya, me too. I've noticed more giddyUp in the last 4k miles.

 

Bought my truck new. Have had it year and a half (18 months) now and turning 31,000 miles on it. Pretty sure it’s broken in. Get 21 to 22 1/2 miles to the gallon in the summer with combine driving and about 20 in the winter.

So far rock solid truck and it’s not babied. I mean I take care of it mechanically/maintenance wise, but it works and plays hard.

 

chart of gas milage from 0 to 30,000 miles. '17 Access Cab MT. no lift, Falken Wildpeaks AT3's for the past 20k. You tell me, is it broken in yet?

 

If you ask someone living in San Francisco I'm sure theirs was broken in the minute they drove it home.

 

WOW that's wildly inconsistent. In my mind I'm comparing the same trips I did last summer to this summer and the average mileages associated. I wasn't expecting to see a bump this summer but chalked it up to break in still, hence the post and the curiosity.

 

Can’t believe that in over 30 posts nobody has made the “200,000 miles it’s a toyota” joke yet.

 

Not a joke, but I'm at 215,000 miles and I've never added oil between oil changes. And I've always done 10,000 mile oil changes. Seriously, my truck runs just as good as new. It is still tight with no rattles or odd noises. They did replace my rear leaf springs under warranty at just under 200,000 miles, but I didn't notice any noise or sagging with the old springs. The body has some character marks and paint peeling on the hood. The seats and carpet are dirty, but nothing mechanical.

I honestly don't recall exactly when, but at some point in the 2nd or maybe 3rd year I owned it fuel mileage seemed to improve slightly. But even that has remained pretty consistent over the years.

 

I never broke mine yet, still sucks at shifting, still gets 16-18mpg approaching 50k.
