I would say all depends on how much you are going to use the truck. I have had v10 fords, a 6.0 ford diesel, and a couple of 5.9 rams. The v10s fuel mileage never seemed to change loaded or not and pulled about the same as my diesels. I stay with a diesel mainly for their longevity. I usually see about 18 mpg on hwy empty, with 30ft gooseneck with 2 Jeeps about 12mpg. I have gotten as low as 9mpg towing though thats with the ford and Rams

My dad's 7.3 idi pulls 18-20 empty on the highway at 65. Loaded down with about 12k in tow it pulled 10.3 mpg at 65. The truck is a 2wd crew cab long bed with zf-5 manual and 3.55 gears. It's not fast but is raliable and cheap to fix plus it is a great waste oil burner making the fuel bill lower still.

87 F250 6.9L nonturbo 4 speed 3.55 in axle. City/HWY 19-21 mpg

91 E350 7.3L nonturbo auto 4 speed 3.55 city/hwy 16-19 mpg. E40D were crappy behind 7.3L

2000 F350 7.3L turbo auto 3.73 City/HWY 16-19 but strict hwy 22 at 60 mph.

I rid of diesel because maintain/ not reliable in bad time like auto store don't stock parts you need immediate.



If I want better mileage it will be next diesel 90's powerstroke F250 or F350 2wd with 5 speed manual plus 3.31 in axle that will able get 25 mpg down highway at 60-65 mph.

I consider it an even wash. I never ran exact calculations. but if you figure

diesel at 18mpg at $4 a gallon... $0.22 per mile
gasser at 15mpg at $3.50 a gallon... $.23 per mile

it gets better when you do your own fuel. Planning on going to WMO setup (I have most of the things lying around save storage tanks). Planning around $1.75 a gallon including consumables for filtration.

I wanted to try a diesel. I figured it probably wouldn't be a big difference. I like the mechanical 12v over a fuel injected gasser. Plus I only have $5500 in mine... Couldn't even find a decent 3/4 ton chevy for that price.


No sense in arguing it. the diesel only gets expensive if you start sending too much power through stuff or have parts go bad.

Only if you plan to drive it 400,000 miles.

I agree. People are so full of crap when it comes to diesel fuel economy. I have owned 2 duramaxs, 4 powerstrokes (3 6.0ls, and 1 6.4L) and never ever have I gotten 20mpg for more then 1 tank.

Best fuel economy I have ever gotten was 20.1mpg with a 02 Dmax CCSB 4x4 and also got 19.8 with a 05 Dmax CCSB 4x4. 19.5 with a 05 F250 4x4, 18.5mpg with a 08 F250 FX4 with spartan 250 tune.

If you want to get 20mpg with a diesel in michigan you have to drive 65mph on the highway, and accelerate at the speed of your grandma. I hand calculate every fuel mileage calculation, never use readout as they are sometimes up to 75% wrong when you put a tuner on the truck.

With all of this said I sill love a diesel, power, but wouldnt buy one next as I dont see a benifit for me with the increased maintence cost over a gasser.

My last work truck was an 04 ford with the 6.0. I has to baby the hell out of it to get 13. That truck just blew up so now they got me a 2012 f250 gasser that gets 12 at best.

Where are all the tdi guys at? 40-50 mpg.

Top gear recently wedged a modern tdi in a rabbit and got 70 mpg. The thing was somewhat fast also.

Or are we just talking about little boy pickups.

2010 Freightliner (no def) with a d13 and 10 speed. REALLY depends on the grade, road conditions, and how relaxed I am. I drive under 65.

I have driven 55 max before and seen 9.8 mph. But, damn that is SO FREAKING boring.

I have seen 9.03 bobtailing, 8.7 with a empty trailer, I usually get right around 7.5 pulling the daily light loads of around 10k around NY. I am grossed at 79,620 right now and getting 5.2.

This is miles driven/fuel used. The MPG on the dash tends to read wrong.

Diesels are needy, picky, and hate cold weather.

Just wait till you need to start adding def along with your diesel in your DD. Most of the stations have def pumps now. But before all the pumps, I was sure glad I had a truck that regens when I seen guys in line with a thing or two of def under each arm.

NG is the future of diesel. Everyone knows it is just a matter of time until the pumps are up. There are many fleets out of CA now running loops on NG. The cost to put these pumps in is a huge expense. This is one of those things I would be totally fine with the government getting behind on to give NG a kick in the butt.

Fuel prices affect everything you buy. I DGAF about the fact it burns cleaner. I am a cheap MF'er at heart and seeing a cheaper fuel that could be available and wildly used if people would just get the balls to demand it makes more sense then continuing to use a fuel that you know will require more technology to keep using and will only increase in cost.

Oh and before someone mentions electric. I have seen and ridden in a electric bread truck. Total after birth of a idea and will never ever make sense until battery technology makes the cells lighter. MPG is not going to increase.

These big trucks are as streamlined as they can get and still getting under 11mpg. The solution is a cheaper fuel.

Welp, my Rabbit was good for about 35 city and 45 highway, my Mercedes 300 SD would get about 25 city and 33 highway, my old GMC half ton 4x4 with a 6.2 would routinely get 22 mpg highway. My current truck, a 1994 F350 dually with an IDI turbo only gets about 15 highway and about 12 pulling a very heavy loaded trailer. The injection pump is turned up on my truck (a lot) so that is contributing to the less than stellar mileage. Having 302K miles on it isn't helping either.

Unless you are routinely towing something heavy, a diesel is a waste of money. It's my personal observation that a large percentage of people buying modern diesels are just a bunch of dick wavers. It's all about "My truck's better than your truck, nah nah nah nah nah.".

A diesel is cost effective for me because 1) I don't have a payment on it and 2) I don't use it as a daily driver. I find it to be more cost effective to drive my little shit box car most of the time and use the big truck on occasion than to just own a fuel pig truck.

The only time a diesel becomes cost effective when you are not towing is when you have a consistent need to jail 4 or more people and need to also have a long bed since that configuration isn't available on a half ton and the diesel does get better unloaded mileage than a 3/4 Gasser...but even then its still expensive to maintain compared to gas truck

Are you old enough to remember diesels in the 70's and 80's? Diesel fuel was butt cheap and stunk up everything within a 10' radius. Diesel cars and trucks where pretty much unheard of, diesel fuel was hard to find unless you were on the highway, and most diesel vehicles accelerated at the speed of dark. So many bad memories of GM 350 diesels in cars and trucks and dealing with cobbled up Olds 350s used to replace them. Bad times.

what does that have to do with my post?

Yes, I remember dirt cheap diesel as a kid, vaguely. I also remember pretty cheap diesel in the late 90's and even the very early 2000's.

The only point I was making is that there isn't a 3/4 ton crew cab long bed gasser than gets over 12 mpg. My diesel can get 17-18, which is the only halfway justifiable way to say you can break even witht he diesel over the gas truck.

That said, I still wouldn't mind downsizing to a half ton crew cab with a 5' bed now that I have zero plans of towing anything on a consistent basis in the near future.

I work for waste management and we are converting our fleet slowly over to NG. The pumps are to go in this winter and new trucks in spring. We are also going to be a refueling station for other fleets.

I don't get what is so expensive to maintain about a diesel? Yes the oil change is a little more, and yeah you have to change the fuel filter more....but they are cheap and easy.....aside from that there is nothing else....my dodge has been really simple over the last two years....parts are fairly cheap and its easy to work on.....i get better mileage towing my trail rig and trailer (7k lbs) than a comparable gas truck would get empty and it does it without blinking.

What am i missing here.....what are all these higher maintenance costs?
