How many miles can you go with a M1009

[bigcrazybell]

How many total miles can you go with a M1009 with a reg non turbo 6.2L with a 27 gallon tank? Seems like I only get around 330 or so.

till ya run outta fuel! lol

 

[krall]

fuel economy

I never go over 350 miles on a full tank. Usually takes about 20 gallons. You don't want to run out of fuel with a diesel.

 

[bigcrazybell]

I would like to know both. Seems like I am only getting around 12mpg and I drive about five miles to and from work at 55mph.

Either you have a very heavy foot, do a lot of idle time, or have a fuel delivery issue. I normally fuel around 350 miles, but do not really get worried until it is approaching 450 miles. My son ran my M1008 out of fuel and it was not nearly as bad as I expected.

17mpg avg you would be at 340 miles with just 20 gallons of fuel, with very little idle time. And 459 miles on a full tank. Starving the inj pump is not a good thing. even at 15 mpg u should be over 330 miles.

I usually fuel up at 400 or 425 with some fuel left.

I have heard the tank holds 25 or 27 gallons but I just put 19 in mine which is the lowest I have let it get. The gauge on mine reads empty at 15 gallons down so I don't take any chances, but I'am curious about how low you have guys let yours get and how much of those 27 gallons you have found are useable.
Thanks

i would def check ur tire pressure........make sure theyre up to the proper pressure.....

low tire pressure impacts mileage bigtime.....

also make sure none of your breaks are dragging, whats the smoke condition on the truck? theres alot of things you can tell us to help diagnose your problems truck might just need to be timed.

How many gallons are you putting in it to get that 330? Are you running 31" tires? If they are bigger you are going farther than the odometer shows. There are sites on the web that will give the conversion factor between tire sizes. My mileage increased when I installed a good IP and fixed a leaking injector and fuel pump. The fuel pump leak began to show as a spot under the truck but the injector leak was only detectable with the engine running and the hood up as it would drip on the exhaust manifold. I was losing 3 to 5 mph even before the leaks became noticeable, which I attribute mostly to the bad IP, by installing a good IP it made a big difference in efficiency.
Still curious on how many gallons are useable in the tank before you get air. I hate to push it too close to empty but the price of fuel varies alot out here. There can be a 50 cent a gallon difference in 10 miles between stations and brands. It can be worth it to go the extra mile if you can. I have never put more than 20 gallons in my tank before it topped out.
Thanks

lindy's right just like POTUS said and you might want to drive DOWN hill more often.....
I'm getting 16mpg in mine and I fill up whenever the urge hits me..... weekend trips or after the boys have been driving it..... Gauge is next item on list as its NMC..... cant decide where to start at the gauge or the sending unit.... decisions ...decisions

My last road trip got me 18 MPG Highway. My gauge works great and I fill it from an 1/8 to a 1/4...no problems.

I regularly get 425-450 out of an in town tank (~20MPG)... about 375-400 out of a highway tank (~16MPG) and fill at about an eighth. It usually takes 23 gal to fill. Doing 65-70 on the highway kills my mileage.
