Running empty at 65 mph is 21, anything over 75 mph and its 18 mpg. Keep in mind this is summer fuel, I just fueled up with a load of winter stuff and the mileage is down a solid 2 mpg.

Towing is 10 to 12 mpg. I wish I could hit the 14 mark.

Cali style deletes.

Ok, I'll bite, how does acetone improve fuel economy?

i found this..

Complete vaporization of fuel is far from perfect in today's cars and trucks. A certain amount of residual fuel in most engines remains liquid in the hot chamber. In order to be fully combusted, the fuel must be fully vaporized.

Surface tension presents an obstacle to vaporization. For instance the energy barrier from surface tension can sometimes force water to reach 300 degrees Fahrenheit before it vaporizes. Similarly with diesel fuel.

Acetone drastically reduces the surface tension. Most fuel molecules are sluggish with respect to their natural frequency. Acetone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension. This results in a more complete vaporization with other factors remaining the same. More complete vaporization means less wasted fuel, hence the increased gas mileage from the increased thermal efficiency.

That excess fuel was formerly wasted past the rings or sent out the tailpipe but when mixed with acetone it gets burned, though the engine still thinks it is running straight gas.

Acetone allows fuel to behave more like the ideal automotive fuel which is PROPANE. The degree of improved mileage depends on how much unburned fuel you are presently wasting. You might gain 15 to 35-percent better economy from the use of acetone. Sometimes even more.



my buddies dad is the one who got me on it. he drove semis for a living and some guy put him on to it. seems to work for me. i drove my truck to work one week with out it and burned a whole tank almost by friday. filled it up again and added acetone and burned almost a half tank by friday. ive been using it for a long time and never had any hoses or orings or anything gone wrong.

18-20.2 empty, 3.73s, auto, smarty on sw1 w/ defaults 65mph.

13 to 14 MPG back and forth to work. Short trips. A few stop lights and stop signs. 17 to 18 freeway. All deleted. I seemed to get better milage right after i deleted everything. Then I started getting bad milage. I have no idea why. I am pretty bummed. It runs great, just bad milage. I do have 37" tires.

90% highway driving at around 68 mph I get 14.5mpg, computer say 16

Driving back and forth to work, 30 miles each way all at 60 mph with 3 stop signs I get 14.5mpg computer says 16

Pulling our 38' Jayco 5ver for 2000 miles. Most freeway, some state highway and mountain stuff. Got 8.62mpg, coumter says 9.2

Pulling 24' enclosed car hauler (8' tall) I got 9.5 all freeway


My truck is totaly stock with 65,000 miles on it.
Bottom line is the milage on these truck suck big time and I am not happy with it. I have looked at doing the delete but it seem the numbers are all over the place if you really gain much. And when you figure the price of the delete it takes a lot of milage to pay for itself in fuel

^^^ Where you will see gains is driving around empty. Towing I only saw a .5 to 1 mpg difference. I chock that up to dragging the big parachute around behind you (aka the trailer).

If i run my truck for another 85,000 miles and gain 2 mpg with the delete I would save around $2,700. Question is how much does the delete deal cost to gain 2 mpg?? Most of my miles are empty.

ok if you go to h&s website and build you a basic delete kit. Its 1300 bucks. This was my reasoning.
If I run 1/4 tank or less I average 25 mpg(100 mile round trip daily)
before I deleted I got 15mpg average.
after like I said is around 25(1/4 tank and empty)
diesel is 3.50 or less a gallon here. So before It cost me 23 cents to drive a mile. After it went down to 14 cents a mile.
So for me I have driven 6000 miles since I deleted. every 11 miles I drive I save a dollar now that im deleted. so do the math. I have saved 545 bucks in fuel so far. So total seeing these gains I will have paid off my investment in 13,300 miles. I drive 3000 miles a month. So to me it was well worth it. Plus you figure the reason I decided to delete in the first place was I clogged the dpf and had to pay 700 bucks at the dealer to fix it. So in my mind it I have paid off my cost already. just my scrambled logic

As of right now my 08 2500 QC 4X4 is completely stock and I have actually hit 24 MPG on the Highway at 67 MPH according to the OHD anyway.

Mopar_Mudder

What exactly do you mean by 1/4 tank????

ramped

fuel gauge 1/4 tank and under. I only fill the truck up when I have either a lot of errands or am going on a trip. better mpg with less diesel in the truck.

Mopar_Mudder

Well in that case your numbers are pretty much meaningless. No way you can get acurate milage readings unless you completely fill the tank, run "x" number of miles, refill the tank and see how much you used. I knew the 25mpg sounded fishy...

mega-engr

I do tend to question the accuracy of peoples "real" numbers and calcs that are over 20 for sure... I've seen my overhead up to 22 before on the highway, but this hand calced out to just shy of 20...

Mopar_Mudder

And when you mod them the computer is way off. My 03 would say 22-24 on the computer but was really getting 16

You can question what my true numbers are all you want. It has no bearing on what I say. I deal with it all the time in the non-virtual world. I tell people all the time that I get 20+ mpg and I am told "bullpucky" all the time. You can also say it sounds fishy or be in denial if you would like. The end game is whether it pays off in 13k miles or 26k miles It still gains enough savings to pay for itself(for me in less than a year) so whether you believe me on my numbers or not, my point is completely valid.
