MPG for new Ram 3500 CTD

Been perplexing me for a while. Why is it no one trusts the digital fuel monitoring but when hand calculating fuel economy they all trust the digital odometer?

I've got a 2500 with the 3.42 gears. I average around 18 (hand calculated) with mixed driving, NOT towing. On the highway empty I can get 22 at 70 mph+.

Towing a 9500 lbs travel trailer gets me about 12.5 on average. I'm very please with this truck. Your slightly taller gears will probably give you a little lower mileage... but still very good for a 7700 lbs truck blowing down the highway!

my mech told me that it will get better after 35,000 miles

Thanks.

Think of miles per pound that Ram does as well by the pound as any compact.

I've tracked the MPG of my 2009 CTD dually since day 1 (hand calculated), been full time since 2010, and I've averaged 15.4 MPG mixed driving. From a low of 7.3 towing against a 15-20 MPH headwind in SD to 21.3 bobtail in the high country around Page, AZ.

I assume your truck is a Dually? Don't complain about 15 if it's mixed driving.

Lie-o-meters are notoriously inaccurate. Hand calculate is the only way to know for sure.

The only thing I can tell you is that I have a 2016 CTD and I have no idea what the true mileage is. The MPG on these trucks is very dependent on how you drive them. Cruising on the freeway on level road (not towing) expect 18 mpg or better. Towing in the hills and mountains, all bets are off, it goes way down. Day in, day out, under every condition, maybe 13 mpg?
