Diesel truck with best MPG

[Diamondpilot]

That Truck with the best milage is the one hooked up to the tow truck!,:dance1:

So that means the answer is a Chevy.....:cool2:

Ran into a guy recently in the Home Depot parking lot (not literally). Had an 85ish / 86ish 3/4 ton Chebby, 4wd ... dumping bed .... plow frame, not the worlds lightest truck. He put a 4bt Cummins / NV4500 into the truck. He claimed he got just under 30mpg highway driving with the truck. It was pretty neat regardless of the mileage claim.

Imagine if they offered a 4BT in a 2013 Dodge 1/2 ton....it would change everything. What idiots decided to not offer a small diesel in 1/2 tons?

I got some pics of this Chevy half ton I saw years ago at the Englishtown NJ diesel drags. Very nice little truck !!!! I would love to own something like this some day.

There is a Cummins forum I check on once in a while. Of course there are all sorts of wild mileage claims. There is a guy on there who has gotten a best of 41 mpg out of his Cummins. I talking 41 mpg out of an entire tank of fuel . This guy can go way over 1000 miles on a tank of fuel. It seems impossible, but he uses extreme hyper-milling techniques. I'm talking the kind of driving where he probably almost never touches the brake pedal. He will carefully plan his routes and the times he drives so he can drive to get the best milege possible. Its a hobby-obsession with this guy. One of his techniques is on the open highway, go 50 mph, put it in nuetral and cost down to 30 mph, then do it all over again, and again, and again...............

Dave,

That's an idea. Though not greatly practicle with my limited brain cells and time.

I drive uber-slow on city & state hwys...like 45mph in 4th gear spinning 1,850rpm...still only get 21mpg last I checked. Truth is I haven't checked my mileage in 4 or 5 years. Think it has improved, but no numbers to back up that claim. I might be getting close to 22mpg in town and state hwys now.

Last time I drove to the mountains, 130 miles round trip, my fuel gauge didn't move much...less than 3/16th. My gut tells me I didn't burn more than six gallons. 130 miles / 6 gallons = 21.66mpg.

I'm probably wrong though :confused3:

any truck pre-EPA will get better gas mileage and weight is a factor. We have an 01 Duramax regular cab longbox averaging 18mpg. My 08 duramax crewcab longbox averages 13.

Anyone run CNG in their diesel? I heard claims of 50+mpg

 

[stu jordan]

If you can't get 50mpg running straight diesel in a truck...no way you'll get it with CNG.

Either way 50mpg is impossible cause there's not enough specific energy in CNG. You "might" get further on a $1 of CNG vs $1 diesel. CNG prices at one time were low...like $1.90 a gallon if I remember. Think it has gone back up though.

That's why I love Agriculture diesels that produce no more than 177hp...they have no emissions crap

Cummins 6BT Agriculture engine is an all mechanical (P7100) diesel...just like my Cummins 98'.

Absolutely not true: for offroad diesels the interim TIER 4 emission is mandatory, which requires the same treatments (EGR, DEF,DOC/DPF) as the current on-road emission standard. The biggest difference is in the measuring cycle.
