700 miles on one tank yesterday......

[jcarey]

We got 685 once and 678 another, always over 650, just depends on how much city driving (usually 15 - 20%), how much stop and go; highway speed 60-65+. I agree on a straight highway trip should be able to hit 800.

"You mention TST. do you mean TSB as I am not familiar with a TST"



JC, a TSB is a technical service bulletin which is sent out by the vehicle manufacturer. The TST they are referring is a aftermarket performance box that oftens help with mileage. There are multiple settings on the box for different levels of power. Clear as mud?



Kinda makes you want one, huh?

Anyone here have a stock fuel tank and hit 700 miles on a tank? Any 800's?

Is your truck an auto or 6 spd? Which rear axle? Also... . Keep in mind that the short beds have a slightly smaller fuel tank (34 gallons) vs the long beds (35 gallons).

I'm lucky if I hit 17 on the highway. Normally get 12-13 around town, 10 towing. Something is just not right! John

PN, you say you got 26 MPG? WOW!

I think his overhead computer readout must be set on km's.

Some guys I talk to that have really run their tanks down can get close to 40 gallons in if you run the tank near dry. If you get about 19 - 20mpg, you're going to get close to 800 miles. DC gives us about 10 percent fuel left when you hit 0 on the DTE display.

And if you want to get that 40 gallons in fast... Use Spooled-Ups tank kit.



It works great

To JPereira from GEM



From Northwest corner of PA in Great Lake snow belt. So we'll see how this DC rig fares in 3 feet of snow compared to my previous F250sd 7. 3.

I get exactly the same as ropinfool2 with my 04. 5 ho same transmission etc. He told it loke it is for stock rigs

Kind of hard to do when the tank on a long bed only holds 35 gallons according to the owners manual.

Sorry, Above posted by Spooled-up (Post #26), copied by me. Below posted by me...

Idea is that his kit fixes the slow fill-up problem, plus makes more of the reserve area of the tank available for additional fuel.

Jim,

Any pictures of how the kit is installed. I saw the link that shows tube and fittings, but can't understand how it will add 5 gallons of fuel?

Thanks, Jeff

 

[Spooled-up]

JPereira,

The kit will only let you fill the raised portion of the tank at the rear of the tank. It's not quite 5 gallons, but you'll fill that portion of the tank in about 1 min or less instead of 5-8 minutes. See my reader's rigs pics for pics of the install and parts of the tank.

This is not fair. I'm still getting 11-12 with TST around town. I find myself smiling at every light now with the TST which isn't helping the mileage issue.

I do pull a 3500 pound enclosed trailer all the time.

 

[RGarza]

Not impossible though. My truck is a short bed 04. 5 and I filled up the other day when the low light just came on and put 34 gallons in it without filling to the rim. RG

 

[RGarza]

I thought that most of the Cummins hold 34 gallons of fuel in the short beds and 35 gallons on the long beds. RG

I have a 4x4, 6 speed, with the 3. 73 rear end. I think its about 8,000# with me and fuel in there. Maybe a bit more. I Will definiatley hit 700 on this tank. I hit a half tank at 420 miles and the DTE reads over 300. So, if I can get 750 before the DTE hits zero, I will go for 800. This is 90% my daily compute of 55-65MPH with half of the commute in the mountains. The other 10% is city driving. My VW TDI never hit 700 miles and no way 800 miles with this same commute. Of course it only has a 14 gallon tank.

GEM, problem is your stepping on the accelerator too much, only way I can get decent mileage out of any diesel is lock er in cruise and go forever. Can't get anything stop'n'going through the cities. Environment & driver technique make all the difference in the world driving a diesel. I can get 4 playing with the big trucks in the hills. Since I get to keep the nickels in my pocket I don't throw in the tank I've slowed down a bit anymore.



Cheers,

Well put. The driver is the biggest variable. I'm trying to get good mileage. Don't want to pay the $2. 09-2. 25/gal. Fuel mileage on mine has contiually gone up with miles and after a rather hard pull with the trailer. I'm at 19,000 miles and mid 20's (22-26) in mileage. 800 miles on a tank is very doable.

Anyone here have a stock fuel tank and hit 700 miles on a tank?

I have a 34 gallon stock fuel tank. I have done many high 600's and a few 700's, but that is unloaded. Example: I put on the trip 713 miles and pumped in 31. 75 gallons at fill up. That equals 22. 45 MPG x 34 gallon tank = 763 potental miles.



While going from Victorville to Sacramento and pulling my 7000 pound Pace enclosed car trailer I went non stop with out any fuel stop. 432 miles and I pumped in 34. 58 gallons at fill up. That equals 12. 49 MPG. Now I did have a extra 5 gallon diesel container with me just incase it started to starve for fuel.
