any body else getting bad gas mileage?

[99firebirdconv.]

i never used to but now im only getting 350km per tank driving in the city, i know that the cold weather here doest help but would spark plugs and wires, and the fuel filter have anything to do with it possible?

350 a tank is pretty good in my book...

[RSFireDog]

No, but you should check and see how far you foot is to the floor when you drive. For a while I was only getting 200 miles or so to a tank, and I figured out that you don't need to floor it at every red light. Gave me an extra 150 miles to the tank.

Oh that and if you do the 'ol 'let it warm up for half an hour' winter thing...thats not good on gas either.

[99firebirdconv.]

Uh..yeah... i know not to have the pedal to the floor, and i only let it warm up for 10-15 mins. Also Wickedsix, its 350 KM, not Miles

I usually refill at 1/4 tank and get around 300 miles to that point. I calculated it to be 25 mpg mostly freeway driving.

I actually got better mileage before I replaced my EGR that was going bad. It was stuck open, don't know if that helped me get better mileage.
And I was getting better mileage before I went from 215s to 245s.

Oh well...as long as I get over 300+ per tank, its all good with me.

All the gas stations should be using their winter mixes, which arn't very good for gas milage.

Or it could be any of the regular stuff. Plugs, filters, tire pressure, driving style. Plus letting it warm up for even 10 mins is quite a bit of fuel.

Yeah I get pretty bad mileage not to mention that my gas gauge is like possessed. It goes about a quarter tank past full and so it stays at full until about 95 - 105 miles then it just starts dropping drastically after that it is weird. But yeah I usually fill up at a quarter tank and have about 200 miles but it is all city driving.

[Blizzard96]

Hey Alex, I think all f-bods are like that. My tank reads 100+ before it goes down from full. From 1/2 tank I'm usually at 250 miles and from there it drops SO FAST...I know when it is at 1/2, I need gas soon. Past 1/4 I don't trust it...

[Alexcab7]

Oh I never let it go past 1/4 because I have no idea what it is really at. I usually do it right when or before it gets there.

I usually get 220-230 per tank, and I calculated it out to around 17-18 MPG most of the time (LS1s get better mileage than me :mad: :mad: )

I only get about 180miles a tank. I thought a V6 would do much better but I guess not.I only have 80,000 miles on my car to.
