 5.7 hemi gas mileage

Does anyone know the gas mileage of the 3/4 ton with 5.7 hemi and high gearing? I'd love to go for the diesel but the five grand option is a little steep for me.

 5.7 hemi gas mileage

I am about to purchase a 1500 Quad Cab with the hemi and the 5 speed automatic...I'd like to know real world experiences with the gas mileage as well, that is the only reason I have been hesitating....

Go to dodgetrucks.org and go to forum. That should tell you more than you want to know.

hemi and gas mileage in the same sentence is kinda like military intelligence. Expect around a steady 12 mpg average from what I have read and heard.

 5.7 hemi gas mileage

Chief, I'd like to be able to buy the Cummins, but the extra $5K+ is hard for me to justify, since I will not be towing or hauling heavy loads primarily. I hope your # is on the low side, the EPA rates this truck I'm looking at 13 city, 17 highway, and much less than that, I'm in trouble!

 5.7 hemi gas mileage

Someone mentioned before (Chief?) that if you "drive barefoot with a pinecone on the accelerator" you will get better milage. That is the bottom line with fuel economy, driving style. Anything can get good or bad milage.

You could work out the math on how long you expect to keep the truck, time and milage, and the fuel savings of the diesel (15 mpg loaded/20mpg empty diesel to 8 mpg loaded/12mpg empty gas) to see if maybe you would be money ahead to just pony up for the diesel now or just to see how long it would take for the diesel to "pay for itself."

 5.7 hemi gas mileage

Back to school

Two pickup trucks leave the dealer. The diesel gets 20 mpg and pays $1.75 per gal. The gas gets 12 mpg and pays $2.00 per gal. How many miles do they have to drive so that the diesel saves $5000?

Cost gas - cost diesel = $5000.
X(mi)* $2/12mpg - X(mi)*$1.75/20mph = $5000.00

Solve for X (mi)

X(mi) = $5000*1/($2/12 - $1.75/20) = 63K mi

Pay them now, or pay later.
Dave

The diesel will have better resale value too, which should be factored into the decision.

 5.7 hemi gas mileage

While we are doing all the factoring; don't forget to factor in the cost of maintenance difference. Most diesels require about 3 gallons of oil vs. 5 qts. for the typical gas V-8, diesel fuel filters must be religiously changed at around 15,000 miles & are about triple the cost of a typical gas filter. My preference is by far for the diesel and Cummins ONLY. In most cases, the pay back period is about 100K typically. With the recent vast cost difference between gas and #2 diesel this year; that pay back period will get cut considerably if the price differential remains the same. I prefer how a diesel drives and its pulling ability while at the same time being very efficient. Do yourself a favor...........drive the hemi pickup and then go test drive a Dodge 2500 equipped with the Cummins HO. Having 600 ft./lbs. of torque at about 1,800 rpm (nearly double what the hemi makes at 4,400 rpm) makes a huge difference in drivability and especially towing. The hemi is a great engine and if you do not have towing in mind and like a fast/peppy V-8; get the hemi. You're gonna hate the gas mileage though. Even with the smaller engine options, the mileage will not be much better as the smaller engine must work that much harder to move a heavy vehicle. In the end it falls down to personal preference. Another point to consider is engine life. The Cummins is designed to go 400K between overhauls (and it can do it with reasonable care). Not many if ANY gas engines will make it past 200K if they make it that far. Some will but not many. I kept my Nissan for about 17 years before I sold it. The diesel will last that long and still have a good resale value as Ken already mentioned.

 5.7 hemi gas mileage

I have the 3/4 ton heavy duty with the Hemi. When I haul tractors on my trailer the truck averages10 to 12 MPG regular driving in the NH hills is aprox 15MPG. I also have a GMC 8.1 w/ alison and get at best 8-9 MPG just driving around. I thought about the cummings, but figured the 5K would buy a lot of gas and the noise would be much less. The cummings is a great engine but it is the loudest I've driven. Good luck.
