Recently I've noticed that my gas mileage has dropped. I was orignally getting anywhere from 400KM (250miles) to 380KM(237) per tank of gas, now I've noticed that its dropped to around 300(187) to 280(175) KM per tank.

I realize that colder weather is supposed to play some sort of effect, but that bad?

Also a recent Dyno Day(oct6), at around 5500-5800 RPMs they couldn't get a reading for my car. The mechanic there said it was due to a faulty spark plug wire. Got GM to check the wires are they said they were fine... <img src="images/icons/confused.gif" border="0">

I'll ask about my dyno #'s later.
BTW my car has approx. 5100miles on it.
Thanks

Yeah, but you aren't stock. I won't mind that happening when I've got a cam as well, but in the mean time

I got 21 MPG that was a trip from Houston to San antonio (180 miles) then city driving until i filled up with 14.4 gallons at 301 miles.

just normal driving, not pimpin' for it.

mileage shot up with the FTRA... I can't say how much, motor is just now at 2200 miles.

I've been getting about 18 miles a gallon, sometimes a bit more. (general driving)
Does which grade of gas you use make a difference? I use the middle one if so. (BP stations).

I get about 18 in the city and 27 on the hwy with 3.42 gears. I would say check the basics ie. air filter, plugs, clean fuel injectors and do the upper engine cleaning. I started losing a bit and these few things brought it back up.
