Just drove from Pittsburgh to Columbus. Set the Cruz on 70 mph. Got 28.0. Return trip set Cruz on 75 mph. Got 26.9. Impressive IMO.

Not too shabby. I know a lot of people we're hoping to see 30+ but I think that was a little optimistic.

I just drove from New Jersey to Vermont and got about the same mileage. All about 75 to 80. You can hear the perfect amount of turbo whistle when hitting the boost on the highway. Not loud or annoying. So much usable power in the 1500 to 2000 rpm range. Loving it so far.

4x4. 3.31 gears

Those are some solid numbers guys, especially 4X4. Really curious to see how it fares while towing.

How many miles on the truck? I know diesels can take a long time to break in (up to 10,000 miles) and the mileage typically increases as the miles go up.

Do you think that can be influenced by certain driving habits people have when driving during the break in period?

Heard both ends of the argument and still not sure what's entirely best for our engines.

Absolutely. From what I've read from most of the performance engine builders is you need to break them in hard to get the best sealing out of the rings. BUT you have to be very specific about how you do it, how often you change the oil, etc. Way more than the average person will do. I think the manufacturers just play it safe with the "easy break-in" as very few people will actually do a "hard break-in" properly.

I can speak from my own experience on a 4-stroke dirt bike engine I recently rebuilt, is that the "flog it" break-in works great. Engine now has great compression and doesn't use any oil. But I followed my builders instructions to the tee, varying RPM, making sure to not overheat, changing the oil at certain intervals, etc.

I've always wondered how much if any break-in is done at the factory. I don't think the engines are test-fired before being fitted into the truck, but I could be wrong.

Not only do driving habits affect the break-in of your engine, but also the new (in 2017) 10-speed transmission is also "learning" how you drive and tuning itself for your driving habits (good or bad)

Just scheduled a service appointment for Field Service Action #18N04 (Powertrain Control Module Reprogramming) that Gary said helped fix his "no start" issue -- going to ask the Service Manager is the learning curve starts over/resets after they apply this FSA...

They fire them up[ in England

Very early to tell, but going from 14 in a Eco, to 23MPG same driving in the diesel is impressive IMO.

Just drove 3500 miles with a brand new truck. Averaged 26.5 MPG. Love the low end torque for climbing hills.

We all have brand new trucks, imagine what they will do when broken in in 30k or so. I bet 28+

 

[GaryGem]

Is that actual MPG or from the dash gauge?

That was actual mileage

By brand new I was referring to 50 miles on it when I left for my trip!
