does any one know how gas milage is with a 6.6 turbo

 

14-15 short trips, up to about 19 highway.

 

Evansblue, we get about 14-15 towing a 13,000lb horse trailer on the highway with our 06 Dmax. Here's how it goes down:

200 miles on truck: 16mpg
35,000 miles: 19mpg
60,000 miles: 21mpg
Duramax at the shop with close to 400,000 miles, 24MPG!!!!!!!!

These engines don't even get broke in until about 100,000 from what I've heard.

 

sweet i may be getting a duramax soon

 

You can't go wrong if you want to pull anything. Great truck and possibly the best engine i've ever owned. Beleive it or not this things got some gidyup too.

 

The information I gave is based on what I have recorded on on dad's 08 Duramax with 905 miles....lol
