However there are fewer units of BTU in LPG so you will use more.

And fewer yet in CNG.

My question is; can I get 25 mpg in the city from a full size truck with some sort of diesel engine? I'm not really interested in the popular cummins swaps but I don't know what all engines are available to swap. I'm not going to hot rod the truck but it will need to be a daily driver in the city. My only requirements are that it be smooth running and not real loud. Any one have any ideas on what a good engine would be? Am I asking for the impossible? Don't hold back on your thoughts on this. My goal is to have a nice truck that gets great mileage. Thanks!!

You gotta be more clear here. Are you swapping or trading this truck? In answer to your first question, that answer would be a highly unlikely. There may be engines that would get you that mileage but they wouldn't be good to drive let alone tow with. 25MPG city is not a realistic expectation from anybody for a full size 3/4 T truck. I would challenge anyone that makes that claim to back it up with fuel tickets reflecting miles and gallons. Not the display numbers. In answer to your second question, any of the big three engines are potentially a "good" one. They all have good records overall. In answer to your third question, not the impossible, just the improbable given todays engines. Someday we will probably be there if the country isn't bankrupted first. There are many that claim that kind of mileage, few can prove it with fuel tickets and odometer readings.

My Bronco weighs exactly 5100 lbs on the scale with the '91 6BT in it and C6 auto/1200 rpm billet converter. I'm only averaging about 20-22 mpg with it, but I still need to tweak some stuff. I wish somebody made a 3.00 gear set for the high pinion D44 front axle, because the stock 3.50s and no overdrive are a limiting factor on my highway mileage. My truck still gets better mileage than my girlfriend's stock Liberty, so we always take my rig to save some fuel. haha!

I'd say an 03 or 04 2 wheel drive regular cab, manual with 3.42's swapped in would be a fairly easy way to get a real 25 mpg. Maybe ditch the tow mirrors and add a dam on the front bumper and I bet you would be right there without having to drive too careful.

my buddy has a 93 chevy crewcab dually running 19.5's with a cranked up 4bt in it, and he gets 27mpg out of it. not as fast as my truck but I get 19-21 out of my truck with a 6bt.
