2006 Vue. 12 miles per gallon?

Something is very wrong. I have on '07 V6 AWD and even driving it hard and letting it warm up in the mornings, I still get 20-22 MPG. Either you are driving exclusively in rush hour city traffic, Filling up with that E85 garbage, or something is wrong with the engine.

Can't be right. Check your math.

Is this oil change at 3,000 miles or 6,000 miles? If at 3,000 miles and they were put on over 7 months I'd suspect it was a lot of short trip and/or stop and go driving. That will kill mileage... I've got a mini van that my wife uses and it is not uncommon for her to get 10-12 MPG around town and has done as bad as 9. When we use the van to take even a few 10 mile trips the MPG jumps up to 16-20. When she used the Saturn she'd get 15-16. I'm using the Saturn now and get 34-38 MPG on the highway dependent upon the temperature and whether I've got the A/C on or not.

Math is right.

1. Fill tank each time
2. record miles between fill-ups
3. Divide by gallons used

There are other factors in mileage results:

Where do you live? What is the outside ambient temperature? Are you running the engine a long time to warm up before driving? Does your community/state/city require oxygenated fuels in winter which lower mileage? Is there lower energy content ethanol mixed in the fuel you are using? Is someone else (ab)using the vehicle or have your driving habits changed?

It is not uncommon to see a reduction in mileage of 10-20% during winter months for the above cited reasons. If you are seeing worse, then take it in and have it investigated. It could be a bad sensor (CTS or O2) causing the computer to send too rich of a mixture. You can also try to see if this is the case by removing your spark plugs and checking for carbon build up which signifies tit is running too rich.

We had the Vue checked out. Two hours at the dealership. Everyone from the service Dept to the showroom area were very friendly and helpful, but no answers yet as to what is wrong. They did run a full system check of the computer system.

Here is something ODD. Apparently Saturn had a 'Fuel Mileage verification Program' on their diagnostic computer system. But GM, in their quest to "Further Absorb Saturn" into the fold decided to remove the program. ^%#@*(!!

They recommended that we keep a detailed diary of miles driven and fuel purchased receipts and then return in a month or two to look into it further .....

Very good points and if you make a lot of short trip in cold weather with cold starts that engine never warms up much and/or let it idle a lot to warm up, MPG will go down the drain so to speak.

(Fill up only when you reach a 1/4 tank and not later than 1/8th.)

In the worst of conditions on repeated short trips on one tank of gas in some of the coldest weather I got 17.9mpg. My engine never got warm going to work. This was with a 98 bonneville with a 3.8L engine. The car was rated to get 18mpg in the city. This is the only time of year I can dip below 20mpg. I can take long trips in the same weather and get 28mpg average. I know Jap motors in SUV's have by far the hardest time hitting their EPA numbers but that is really bad if you are doing everything correctly.
