Default How accurate is the fuel info (mileage remaining)

Just curious, my low fuel light comes on and the info center display tells me I have approximately 90-100 miles left, is this fairly accurate? I'd hate to run out of gas because of going by the info display, anyone ever run out of gas because of this?

Joe.

I have found it to be quite accurate. Except on my car it'll say "low fuel" once I get below 50 miles fuel range.. I've never run out before it said low fuel though ever. It is possible if your fuel pump sending unit is bad though.

When you get the "Low Fuel" warning light (shaded amber area on instrument cluster gage) on the DIC, it usually means that you have approximately 3 gallons left in reserve. It doesn't hurt to fill up at this point. I push mine to the limit (not a good idea, I know what I can get away with) because I know what I can get out of a full tank of fuel using the trip meter. And as far as the "fuel Used" indicated on the DIC, I usually have to put in one more gallon than what is indicated on the DIC.

I think Ive been down as low as 4-5 miles indacation on my DIC.
but that would only be once since I had the car.

and Mark im pretty sure my "low fuel" light came on around 9 miles or so.

I've yet to run out of gas, but I'm not trying to push it either. I just find it a little odd that it would tell me "low fuel" when I still have approximately 90miles left on the tank. I checked it and it said there was still 3 gallons left (15 gallons used), so if it'* set to come on at 3 gallons remaining, I guess everything is up to par. One day if I get brave, I'll try to push it to see how far I can make it going by the DIC reading, my luck I'll run out of gas with it showing 50 miles remaining, lol. Thanks for all the info fellas.

Joe.

well if your drive is on the highway it will factor in the gasmilage into that estimate, so that 3 gallons might give you 100 miles

Joe, that "Low Fuel Warning" is a very conservative estimation at best. The Fuel Range like Pat stated takes into account the fuel usage calculated by the DIC. In real simple terms it is speed over distance (mpg), you will notice that the fuel range varies from hywy to city driving. Example, if you drive highway for 1 hr, and the fuel range is 300 miles remaining, when you get off the turnpike, then drive into a city (stop & go) the fuel range will drop considerably because now mpg'* just dropped down. All those data that you can read out on the DIC are general estimates, and shouldn't be interpreted as exact values.

The fuel range....Does anyone reset this each time you refuel? Should it be reset in order to remain accurate for the current info? Or will it calculate based upon the other settings? I never bother resetting it - but that'* be cause I don't use that feature. I use the trip meter instead. I know I can get 350 miles or so out of a tank in the winter...so Ijust watch that.

My DIC is a little off (lol...never mind)...it reads 1 mpg higher than the actual Average MPG. And I check it each time....use different pumps/gas stations....

Tracy, I don't think the fuel range is a resettable function. I'll have to check it out. what I think is when you top off your fuel tank it adjusts itself accordingly taking into consideration inst. fuel economy as you're driving. It constantly is changing depending on city or hywy driving. Oh yeah one other thing, every time I fill up, I almost always put one more gallon than what the Driver Information Center reports for fuel usage.
