DIC one gallon off...
 

I've had my '03 SLE for over 6 months and the fuel used reading on the DIC is always 1 gallon less than what I put in it at the gas pump. Weather it be city or highway driving - warm or cold. Why? What would make it consistently off by 1 gallon, is there a way to adjust it? I've never had any trouble with the car, or repair work done. Any ideas?

You have a fuel used reading in the DIC? Hmm...either im stupid or I don't have that in my 00. I have a Miles left reading....

Yep. My '03 SLE has fuel used, miles left, average fuel mileage, current fuel mileage, oil life and tire inflation.

That figure (Fuel Used) is calculated by a processor and is an approximation at best. I also usually put a gallon more than what the DIC reports in my tank when filling up. If you fill your tank the same way every time you fill, then to me that is a more accurate determination of how much fuel was used between fill ups. I also calculate mpg by the meter reading on the pump & the trip meter reading.

01's have it also? I feel ripped...

You ain't missin anything Rogue. It's just more gimmickry imo. :)

The 00's don't have this, weird. I miss the Aurora DIC which also had avg/speed. Figure 4 hour trip avgeraged 74mph to the cottage, missed that on my last trip, Oh well, not complaining.

My DIC is usually within 1-2 tenths off on everything, pretty good. The aurora was 4-10 off sometimes.

Today, current average gas millage was 16.1. Got love the winter warm ups, when my remote start goes on next week, will be even lower.

I have a 2k and I have a "fuel used" as well as the other stuff your talking about.

I have:

Fuel Range (miles left)
Battery
Tire Pressure
AVG MPG
Instant MPG
Oil life

I wonder why yours would not have it?
