Truck saying 30 miles til empty and then within a mile saying empty.
I was driving on a long trip 2100 miles. Got through some other problems of coolant being low, etc. Then I go through a 250 mile section of nothing in Texas in between Fort Stockton and San Antonio in a town near east Sonora, Tx. My truck is climbing a hill, says 30 miles til empty someone else is driving while I'm asleep and he tells me whats up when I wake up. I said, ah don't worry about it, I'm sure we can fill up but it was going to be close as we were 24 miles away but close enough. Then all of a sudden there is like .3 miles go by it has dropped 4 miles per .1 mile of actual travel. So we barely get a mile before it says its empty. We pull over seeing a DOT crew working and got some Red fuel from them thank god because it was thanksgiving the next day and we would have been stuck so i put that in there syphoning it out and into some bottles. I don't know how to trust this truck after all of this stuff going on, does anyone else have these problems? I'm starting to really doubt that the computer is accurate with mileage and empty fuel usage. I was thinking maybe turbo was on and burning that fuel but no way that fast and that much even up hills, we were doing 70mph with a 20' enclosed trailer that was empty.
Re: Truck saying 30 miles til empty and then within a mile saying empty.
My wife's Yukon did the same thing on it's Lie-o-Meter. It went from 60 Miles to go, to Low gas warning in just a few Miles,we learned when it got to about 100 miles, to start looking for a Fuel stop because it would start dropping fast!

Re: Truck saying 30 miles til empty and then within a mile saying empty.
Mine hasn't jumped from some to 0 that fast but when mine gets to 0, I still have at least 4 gallons left. Today, I was down to 9 miles when I filled up. The pump quit at 26.1 gallons. I have a 31 gallon tank.

Re: Truck saying 30 miles til empty and then within a mile saying empty.
Thats why I never wait to get that low to hunt for the fill up station. When it gets to about only a 1/4, I just fill it up. It also seems to be cheaper to fill it up from a quarter then when its empty...
Then again, it might be my wishfull thinking [img]/forums/images/%%GRAEMLIN_URL%%/crazy.gif[/img]
Re: Truck saying 30 miles til empty and then within a mile saying empty.
its like this: You bring in $500 per week and through the first 3 weeks of the month you only spend $100 total. Your weeks till bankrupt meter now shows 42 weeks until bankrupt. You go shopping one day and spend $500 and then go home and pay another $500 in bils online. Your spending rate jumps up to $7000 per week and your weeks till bankrupt meter shows .17 weeks till bankrupt.
when your short term rolling average is 15 mpg then 2 gallons remaining in tank is 30 miles. When you stop and take off and the short term rolling average is 1 mpg then you suddenly have 2 miles till empty.
That is the correct way it works. The computer on the truck cannot predict that you will let off the throttle and the mpg will go back near 15 mpg so it reports to you what distance you may expect to go at the CURRENT mpg.
If it was all uphill at that grade to the fuel stop you were in deep doo-doo. Since you would have levelled out after the climb you probably weren't going to run dry in 4 miles.

Might be better to carry 10 gallons of fuel with you if you are that far between stations. The fuel pump will fail prematurely because it is not being lubricated as well with foamy fuel/air mixture and your injectors ($$$$$) are on the way to shortening their life too.
