[Yaba3800]

ya.... thats not gonna make that much of a difference because ive tried driving slo and i got to 245

[V8 Killer]

Get a big tune up
check your tire pressure

[Yaba3800]

what do you mean by a tune up? plugs and wires?
and my tire pressure is both at 32
ive put fuel injector cleaner in it and it didnt help much

Um, can't help with suggestion for better gas mileage, because I get the same 250 miles per tank.

Brand new = 250 per tank

At 7000 miles started modding. Ram air, 1.9 Rockers = 250 per tank

At 9000 miles 3" exhaust went on = 250 mpg per tank

Currently at 10,000 miles...just added Super Charger last week. Am looking at 250 miles per tank. (a little less...been testing the PSI output quite a bit lately. :D )

SO, my tank holds 13 gallons. After using 13 gallons tank on very empty. Fill up always = 13 gallons...never 14.

Do different year firebird/camaros have different sized gas tanks? My owners manual says fuel tank capacity is 16.5 US gallons.

Time for some algebra...

if 13 = 250 then 16.5 = 317 miles.

Average mpg = 19.2 with an equal blend of city and freeway miles. I am drivin like Steve McQueen most of the time. Not bad fuel economy for what I put this car trough pretty much everyday.

Would anyone care to offer feedback concerning the descrepancy between my owners manual stating that the 2001 firebird has a 16.5 gallon gas tank and that from day one that car has always taken only 13 gallons. (gauge is fine...same as day one out of the dealer.)

Yaba3800... If nobody replies to my above post I will be making a new thread of my own on this subject. What mileage are you getting? City/freeway, etc.?

[dorkins]

just got 269 after putting a bopttle of injector cleanor in.. (got 180 on a full tank before)

after that tank, mileage went back down... now i put stp cleaner in (with techron) and im at 100 miles, and 3/4 of a tank to go


my ? is... how far past the empty line can we go? i dont want to find out myself... but i have yet to see low fuel light or nething when needle is almost below the line... how many gallons would i have left?

[HeadyFirebird'00]

I presume its around 1 to 1.5 gallons of gas, at the "E" line or a little bit before it.My gauge will go past the "E" a smidge. My "Check Gauges" light lits up at 2-3 gallons left. I rrealized this after i topped the tank. The pump always says between 13-15 gals. filled up. Thus leaving 1-3 gallons that existed in the tank prior to fill. .... And 2001s have a 16.8 gallon size tank I believe.

[grayman]

HeadyFirebird...yea, but....that just seems like a lot...4 gallons when on E for longer than I should prabobly do. hmm...maybe it is a good thing in the long run.

But mileage comparisons here should at least be done as MPG rather than Miles per tank. sheesh...miles per tank is something the mustang newbies would talk about.

You're lucky, when my gauge hits e, its empty. I usually get about 19 mpg. My car also has 151,000 miles. Highway i get about 28 mpg, with AC going full blast.

[HeadyFirebird'00]

i didnt say anything about 4 gallons... and thoze numbers were real rough estamets. i didnt pull out my graphing cAlculator and wize this stuff. i used some mental math with maybe some rough estamets. but see for your self, drive it til its e see what happens. you never know unless you try it.
