How accurate is the MPG guage?
#1
I have been playing around with the fun info on the electronic guage. The one I watch the most is the MPG readout. I usually reset that along with the "Gallons Used" when I fill up with gas. After the tank is empty, I check the readout again to see what MPG I ended up with.
I've done this several times and the numbers are all over. My weekly driving is pretty routine and varys slightly, but I've gotten everything from 14.2 MPG to 22.1 MPG. Anyone else notice this or know how accurate that guage is?

I think it is pretty accurate though, and at $1.05 a litre at the moment I wish it was broken, so I didn't know how much gas I was using

I was wondering that myself. In the Owners Manual it talks about how it can throw the results off if you fill up someplace where it's not completely level. That will throw off how much gas you can put in your tank and thus throw off your results.
I first thought I was getting really good mileage with my V6, then I noticed that it said MPH in the message center, not MPG. I'd been looking at the average speed, not miles per gallon! Errr! :bang:
I'm only getting about 18 MPG right now with about 50% highway driving. I'm hoping that it will get better after the engine has had a chance to get broken in.....

The reason it's all over the place is, if you reset it after every tank, it has little history to base fuel consumption on.
If you leave the miles per gallon be over a long period of time, it takes a while for it to change around, as the average is more set in stone.
I’m not sure if I explained it very well. Think of an average of anything, with more raw data it takes more to shift the actual average.

12,000+ km on my car and I average 23-24 mpg. I keep track of when I fill up and calculate what I should be getting. It is very accurate. You cannot reset it everytime if you want an accurate reading. Only time I notice it is not very accurate is after I had too much caffine and drive around like a maniac. I see my mpg drop significantly and can take at least 1 1/2 tanks of gas before it gets back to normal

Bart - weren't you suspicious when it said you were getting 80 mpg??

Wow! How fast do you guys drive to get an average of 80 MPH? No, my average was 25 MPH, that's why I thought it was MPG......

With just over 9K mile on my baby and a 28 mile round trip drive to work each day I'm getting 17.3 MPG. Now I'm heavy footed and have a tendancy to enjoy the ponies under the hood.
I took a little mini vacation 2 weeks back and stayed out of the gas as much as I could after calculating my milage I got 23.5 for the trip. Went a little over 400 miles and did 60 most of the trip.

There's a pretty wide range reported on the MPG Poll thread
Post your comments and take the poll. It started as a way to get people to 'fess up to their heavy footed habits. But, it's interesting that people are getting such a wide range of mileage.
