At what mileage was your truck "broken in?"

Everyone knows new vehicles get slightly lower gas mileage when the motor is brand new. I'm curious...when was your truck "broken in" meaning getting its best gas mileage?

Last summer I was only maxing 20-21mpg between 5-10k miles. Now I have 17k on it and I seem to be getting 22-24 consistently at speeds between 60 and 70 (very much the same driving style).

Just curious as I wasn't expecting the increase in mileage between years!

 

Right around 15k.

 

After 5K I don't think I noticed any break in changes after that point.

 

I'm....I'm not sure. I keep trading them in and getting new ones.

 

Knock on wood...No break ins as of yet.

 

Truck was very tight when new new, but always got over 22 mpg in the summer. Now at just under 10k miles its running better and better. Still getting between 22-23 mpg.

 

93000

 

80085 miles exactly

 

42

 

No wonder this place gets named the dumbgeon.

 

Thats why i stickily post my questions on mom-run facebook groups, much better moderation

 

1000 miles

 

I reached full brake-in around 17k miles. That's when oil consumption reached zero. MPG never changed.

 

Yours was consuming oil? Your timeline matches up to mine.

Always thought a new vehicle was broken in before 10k. Wonder if it varies model to model.

 

After first tank of gas, started getting consistent MPGs.

 

^^^ Are those dry miles?
I've found it to be nearly half that here in the Southeast.

As a freelance proctologist, I've broken in my fair share of minivan engines..

 

Ya, I always thought brake-in took about two hours. But I added a catch-can the first few months, and a year later the can stay's empty. First 12~15k I would get 3 oz every
7k miles. For the last 10k miles I'm not getting anything, not even a drop/drip of oil.

 

I must have a lead foot. I average about 70-80mph with ~16.9-17.5mpg. Maybe I should slow down a little to save a couple bucks.

 

My '21 Taco has a bit over 6K miles and MPGs are still improving. Currently (by calc) running mid 18s. I don't rely on the onboard calcs as it's been off by up to 3 MPG.
My '06 Taco's MPGs pretty much topped out around 50-60K miles.
