2004 alero loosing gas really fast

I'm still confused about the first post.. What is 10k? It can't be 10,000 miles unless it's strapped to a rocket engine and it can't be 10km since thats about 6 miles which would make him driving 42 miles on a full tank.. Which seems like there would be a leak in the gas tank if anything else...

Unless there's a metric prefix I forgot about...

Yes I did mean km, Iam looking at about 130-140km on a full tank of gas. But I also have a car starter that I use because its winter and get to -25C average in the morning.

Well 80 or so miles on a full tank is weird and I have no clue why that is..

If you only drive the car 10 kilometers per day the engine never gets warmed up to operating temperature. This can carbon the engine internally and it will consume alot more gas. I don't know how many km's on your car but if your getting close to 100,000 km I would put new spark plugs in it. I myself get better mileage with esso and sunoco gas. Shell gas mileage sucks.
Does your temperature gauge go up are stay down at the 40? Thermostat can cause this but usually sets a SES light on and a code for this. Warming your car up uses alot of fuel. Why don't you try a week without using the car starter. I bet you'll see great results. Some times after market accessories such as car starters and alarm systems tend to make the computer dump more fuel also.

I just ran the tank almost dry and I got about 200kl per a full tank. I really dont know that that will translate into miles.

That is only 120 miles!!! Or about 10 miles per gallon on 12 gallons! Ouch!! I am only getting 18-19 which is terrible also, but 10??? You have a serious problem. No leaks? Does it run like crap?

i figure i got about 80miles a day to work and back total trip and when i get back on the third day i have a quarter of a tank left. give or take.

Using fuel with higher octane than regular unleaded (typically 87 octane in the U.S. at lower elevations) won't hurt your car. It will, however, cause significant damage to your wallet! It is completely unneccesary in an Alero.

Make sure you are accurately calculating your mileage.

1. Fill the tank with fuel until the pump automatically shuts off. Do not top off the tank.
2. Reset the trip odometer.
3. Drive the vehicle. You don't have to drive it until the fuel gauge is on "E". The gauge reading has absolutely nothing to do with computing the mileage. It doesn't matter if the tank is still half full or completely empty as long as you've used a reasonable portion of whatever fuel is in the tank.
4. Refill the tank until the pump automatically shuts off. Do not top off.
5. Record the mileage (or km) on your trip odometer.
6. Record the number of gallons (or litres) of fuel it took to fill the tank.
7. Divide the mileage (or km) by the number of galllons (or litres) and you will have sucessfully calculated the actual fuel economy of your car in mi/gal (or km/l).
8. Repeat if you want to establish an average over time or periodically check the mileage.

If you always run 87 oct. you can get a lot of carbon build up. Just my expierence.
