For those upset about mileage

[Yo Hoot]

It's not just the Cummins. It's the emissions changes that seem to be hurting all brands.



Here on the GM board a bunch of members posted their mileage spreadsheets. Some in the 8mpg range while towing.

Sounds good, but what about all the people with the 600 that say they are getting 19+? They also have the smog engines, don't they?

Ive got a 600, I just got back from another 240 mile round trip, empty, from my house to San Diego and back, and My overhead said 17. 5 mpg. . at about 80 mph the whole way home. Calculated at fill up it worked out to 19. 5 mpg. . My overhead has always read 2 mpg low.
