Tundra Break-In Mileage

I took delivery of my 2023 Tundra Limited Crew Cab (4x4) on April 16th of this year. I now have 1,500 miles on her and have been tracking the real world MPG since day one.

I recorded my average MPG (from the onboard computer) for 0-500 miles, then reset it for 500-1,000, then reset again for 1,000-1,500.

It should be noted that the majority of my driving is on winding mountain roads at high elevation. I typically average 2-3mpg less than equivalent vehicles doing average city/highway driving.

Air pressures were checked at each reset and held 40psi the whole time. My wife drove the majority of the miles from 1,000-1,500 and typically gets slightly worse numbers than me.

Here's what I came up with:

0-500: 16.0mpg
500-1,000: 17.0mpg
1,000-1,500: 17.6mpg

So a steady increase across the board. I will update this thread when I hit 2,000 in a couple weeks, then again at 2,500 and 3,000

 

Yeah it will go up more, I get around 18.6but qm switching to some toyo open country's which I'm sure will get less mpgs

 

It's been reported on a different thread that running in Normal mode gives better mpg than Economy mode. I was running Economy for the first 4k miles but switched to Normal for the recent 700 miles. Don't have accurate data based on real fill ups, but previous typical truck reported mpg for my driving style and area was upper 16's, now mid 17's. So I'm turning into a believer that Economy mode does nothing for mpg.
