I have had my Cruze now for 15 months. Bought it used in almost perfect condition with 32000 miles. I now have 55+ thousand miles. And since I bought it, every time I fill it up, and check the numbers, the trip computer says X gallons used, which varies anywhere from almost a gallon to exactly a gallon LESS than what I put in.... any suggestions as to how to adjust this? Thank you. Darren.

Just the nature of the beast. They all do it, and it's based on the algorithm that GM uses to determine MPG/fuel used. Some manufacturers are able to get a more accurate estimate from onboard computers than others.

Yeah, unfortunately there's no way to calibrate it, you just live with it. I use fuelly so I know how many miles I've actually driven over how many gallons I've actually bought making a much more realistic average in my mind.

I drive a semi truck. I know those things get calibrated for sure... The pumps I mean. Look at the sticker on your pump. Most places check calibration. Maybe your paying for a gallon more of fuel than what's going in...

Seems like since I got the emissions recall programming done last summer my pump gallons and gallons used have been much closer. The pump gallons is always a little more but they are closer than before the programming.

The computer for gals used is right on with my diesel model...but you have to spend the time to slowly top off the tank. I can pump another two gallons in the tank if I pump real slow after the nozzle clicks off....but I know most people aren't going to take the time to do that with each fill up.

I can't. There's always people behind me

Then get a small gas can, and pump that baby up nice and fast, pull out and the use your 2 gal gas can and slowly add it. I did this at the beginning of a few road trips. I would top it off until it wouldn't stop clicking all the time, and then 2 mins down the road, and a few left and right turns, and it would go from full to off full by a bit. So pull over, add it, and sure enough, all the air is gone by then and it takes what it's supposed to take.
