ate the tank of gas

I can usually get 275+ miles to a full, to the top of the guage, tank. Finished filling up the tank (well the guage was to the top when i got in the car) used this gas station before. Drove about 60+ (not all in one night) and the gauge was down a quarter. I have put a total of like 180 miles and the tank is at 1/4 left. Now usually when the tank is filled just a little over (so the guage is just above full) i can get close to 40 miles before it is even at the full line or just below. I seriously thought i had a gas leak on the way home and the guage was down so much after it said it was full. I don't smell gas, or see it under the car for that matter. But it seems to be drinking it this tank for some reason...and I haven't changed my driving behavior at all. Any ideas?? Bad gas??? Loose filter?? Does this have a filter? hahaha

Wow, that is really sucking it down!. Have you made any mods recently?When I fill mine up, I usually get about 70 miles before it starts to drop, 120@3/4 tank, 200@1/2, 300@1/4. Mine has been regularly getting about 30 mpg. (base, 5-speed, Injen CAI) I did notice my gas mileage REALLY drops if I cruise above 75mph.

That's how my guage goes EVERY DAY vibechick. I've got the 03 GT..and it just sucks through it, around 20 MPG, refill at 226 miles on the trip meter.I'm hoping it's just the cold.. and I know i'm sucking a little bit of gas with the remote start...

For a useable accurate mpg you need to divide the miles driven by the amount of gas needed to refill the tank. There are too many variables when it comes to just guestamating mpg by fuel gauges. If you write it down each refill then can keep an accurate running log of how your car is doing, this can be made even more accurate by averaging several tank fulls. I find that if I fill on the slowest setting and stop when the pump auto-stop engages, it gives me the most consistant refills. Guess I am a bit (removed) about mpg, but thats why I bought this car and not a Crown Vic to commute in. I have found that the single biggest variable in mpg is if I drive 65 or 80 mph, temperature,windows up or down, a/c and a couple extra pounds in the tires made no difference at all.

I have had some big variations in mpg from one tank to another. Sometimes it can be a change in my driving habits. Pushing the car hard hurts mpgs, getting stuck in a big wad of traffic flowing at a steady, sedate pace helps mpg. No matter how consistently I try to fill the tank, I think there are still variations. It could be that for this particular tank of gas, the gas pump shut off earlier than others you have used. Maybe this pump was just a bit sensitive that particular day. It could be that this particula tank of gas wasn't quitet as full as others, so it will appear that you're getting bad mileage out of it. It's possible, no guarantee.I keep pretty good records of mileage and gallons. Started keeping track after about 1000 miles, have recorded each of the fillups for the following 36K miles, and I average mpgs over multiple tanks to reduce any variation in how full I fill the tank on any particular tank. You should pay attention to mpgs to see if the poor numbers continue, or if it goes back to what you're used to. If you haven't had any noticeable decrease in power/performance,, and the next tank is better, then it's problably no biggie. If the car loses power, or your mpgs drop and stay down, then you have a problem.The cars have fuel filters, which are part of the whole fuel pump assembly. The fuel pump is in the top of the gas tank, accessible iunder the rear seats. It looks like a hassle to replace, but if it was loose it wouldn't cause you to leak gasoline on the ground.

I have no mods on it yet (oh where is my income tax return??) But I have also done the same lame routine driving back and forth to work etc. Normally a full tank can go very close to 300 miles. The tank was just about empty when i filled it up. This last time i only put a 1/2 of a tank in it. It looks to be doing better, but i'm not at empty yet. I'll see on the next fill up. Thanks for the help!!

I've been keeping track of my mileage fairly regularly. I find that wind has a HUGE impact in how much gas the Vibe uses (base 5spd). Into a strong wind it can chew the gas hard, and with a wind at your back you can go forever on a tank. The wind plays an even larger role if my bikes or the canoe is on top. As well, I've found, after going through quite a cold spell over the last couple of months here in Eastern Canada, that when it's really cold out, you will go through a lot more fuel.Hope this helps - cheers!

I've not had this problem with my Vibe, but with my Olds Cutlass ... it sounds silly, but check the gas cap. Mine wouldn't seal properly, or just not on tight, it would cause a dramatic decrease in the fuel economy. I had a friend who had a Cutlass as well whose gas cap was cracked & had the same problem with reduced MPG.

You know, i was getting right at 300 miles (avg) per tank in my GT and on the fill up before the one i am n now i added some fuel system cleaner to the gas and on that tank and so far on the one i'm on i have been getting about 335 miles. My Vibe has 7500 miles on it.

Driving 45 miles kills a quarter of a tank in my car, base auto Vibe. Dunno why, could be some of the stuff I've done to it, or the addition of a power-sucking competition system. *Shrugs*

cohocarl · Post by **cohocarl** » Tue Mar 09, 2004 6:54 am

I filled up tonight. 342mi, 10.6gal, =32.26mpg. It's been a little warmer around here the last couple weeks (40 during day, 25 night +/-), and I'm getting about 3-4mpg better than I did during the coldest periods of the winter.

Its not even broken in yet. It has seemed to get better since the weather has been warming up, I average so far about 500km to a tank. I will be trying to get my hands on a CAI this summer also, suppose that will either improve or destroy my fuel economy lol. Will remain to be seen.

I have got my vibe for about a year (April) but never experienced those mileage magics you guys mentioned. My Vibe usually takes 10L for every 100km (23.5 mpg) and even worse in the winter. Yes, I drive mostly during rush hours in city, and the Vancouver area is pretty hilly. But... Could anyone from Vancouver give me a rough idea how much gas your baby costs you?

What kind of Vibe do you have (Base, AWD, GT)?I have an AWD, and driving 99% highway, I get just over 8 L/100 km in the summer, and about 8.5 L/100 km in the winter.

I've got a 03 Vibe GT, and here's my mileage (it's in American MPG, which is different than the MPG posted by the Canadian gov't).I was in Vancouver in early October, so you can see the mileage there, about 25-30 mpg, and that was about 1/2 city, 1/2 highway. The other driving was taking place in Calgary, and I've noticed that even when I drive with a light foot, I'm still getting lower mpg's than the posted mpg. I think it probably has to do with the alititude.

This graph shows my mileage for the life of my second catalytic converter (long story about me & catalytic converters). Anyway, I'm in Saskatchewan, which is lower in elevation than Calgary, but not as low as Vancouver. I drive 99% highway. The notation about downshifting is when I figure that the converter decided to crap out on me ... see how the mileage has been steadily climbing? Wish I knew if this was due to cold or catalytic converter.

Looks good! After that inital break in, it's a pretty straight line.

Thanks,It seems you got better gas mileage in Vancouver, it is somehow much flatter in Calgary. This confused me a bit. I miss my days in Alberta, what a big sky.

I guess with a lot of stop & go driving & the automatic, you might not see the 8 l/100 km that I'm seeing on the highway, but I just thought 10 was high.I guess you'd have to compare with somebody else who's got the same sort of driving patterns, and is also at sea level, because it seems that elevation makes a big difference.You may have grounds for complaint to GM because you're really not getting anywhere near what the Office of Energy Efficiency has rated this car at (8.3 L/100 km in the city for the Base w/ automatic).See http://oee.nrcan.gc.ca/vehicle...=PONT for ratings.

iburgess · Post by **iburgess** » Thu Mar 11, 2004 10:32 pm

I'm at sea level on the other side of the country (Halifax). I have a base 5spd. I will get 7-8 L/100km in the city, and 6-7 L/100km on the highway. It's a little worse if it's really really cold out. It's a lot worse if the bikes or the canoe is on the top and/or if she's loaded down with gear. As well, wind plays a major factor with this car on the highway.CHEERS!

iburgess, your numbers are bang-on with what the specs are. So, it's not like the numbers are unattainable, which is why SkyTrain has got a legitimate beef. Glad to see that someone is actually getting numbers that match the specs!!I'm not matching the highway specs, but their definition of "highway" is 70 km/h. Who has time for that?

Jahntassa · Post by **Jahntassa** » Fri Mar 12, 2004 4:05 am

(removed)? They're saying 38/42 MPG for the GT? HA! I've been getting more like 20/30! (removed)?

The website you're looking at is Canadian, which uses imperial gallons, whereas in the states, you guys use US gallons. The conversion is:1 Imperial gallon = 1.201 US Gallons
