With emissions in full swing, diesels are not getting much better then gas mpgs... Some claim a huge amount but for us that have driven both, we know..... Also TFL just posted 15mpgs out of their trip with a diesel Chevy on the hwy. Granted it was a factory off road with a slight lift, but a lot of diesel trucks are running around here in Florida with huge tires and lifts, and despite being so called tuned, you know they are not getting top mpgs compared to the older diesels or stock versions. That Ford 6.2, Chevy 6.0 and Dodge 6.4 are all very well built gas power plants and maintenance is next to nothing... My truck get 17mpgs unloaded hwy at 70 in Florida.
I'm not buying the modern gas gets nearly as good mpg's as a modern diesel in a HD truck. My buddy has the same truck as mine but with the 6.0 liter gas, I get far better mpg's than he does.

Just my experience on my 09 6.0 gas 2500HD 4x4 with crew cab. I have been getting 13.5-15 in the city as well. Granted it wont be better as a diesel, but in todays gas trucks are far ahead of where they where 10 plus years ago in power and economy. With overall ownership gas trucks to me is just cheaper over the long term. It takes a long time to break even on a diesel. Hey I like diesel trucks to, pulled around with the duramax and a cummins. I like the power they can provide, but not the cost ownership anymore, just not worth it to me. At only 44 I want money in savings to retire one day...!!! And guys if you leave your diesel trucks stock, I'm sure your mpgs are good. The problem is that not many don't here in Florida, everyone lifts them up, puts massive tires on them and then complain about the fuel mpgs. Now the pre emission diesel trucks are awesome... very little to go wrong and no emissions choking them out or creating issues. Again just my overall experience in the years that I have been operating and owning trucks. Oh forgot on edit....tell your buddy to look at blackbear performance, I have the live tune and have got better fuel mpgs even when pulling. Again just my experience, that company does wonders for GM trucks.
