Thinking of trading my current truck cclb 6.2L for a new cclb 6.7. I know everthing has issues ( i had a 6.0) i am very happy with the 6.2 its been flawless for 2 1/2yrs and 60k. What are you guys seeing for mileage? Empty? Loaded? I tow at or slightly above gvw frequently so any issues with hard use? I count on this truck highly! Before i drop 55k on a new diesel i want real world opinions and numbers. I will buy another 6.2 if need be but with 4:30 gears, but if i can go from 7-8 mpg towing to 12-13 and 13.8-14.6 empty to 20-21 its a no brainer as long as i can rely on it day in day out. It will have all the proper maintance i am a heavy truck mechanic. I just want a broad spectrum of opinions and data for my decision. I don't see them lined up at the local dealers but who knows? Any info greatly appericated thanks in advance!😀

 

You won't get 20-21 MPG out of a new 6.7L motor. Towing close to or over 20k you should stay in the double digits.

 

I know i wont get 20's towing if you read it closly i was hoping to get 10-12.

 

Yea....I can read, thought my reply was clear enough.

 

I've seen several of the new 6.7 Powerstrokes get right round 20 unloaded. Towing all depends on your driving style, weight and location.

Heavy assault was not saying you can't read. Have had so may people not read throughly. Thx for input.

 

I have a 2014 6.7 cummins and i get 18-20 stock and 12-14 towing if that helps

 

Thanks Luke i bought this back in September and got over 10 k on it so far and live it!
