RE: Gas Mileage Sucks - 4/21/2007 11:27:17 AM    BadgerHoe   Posts: 25 Joined: 4/7/2007 Status: offline This is just my opinion here, but I think as long as GM insists on running 3:73 or 4:10 gears AND giving the 5.3 the capability to run corn gas - read bigger injectors and the capability to feed more fuel to the engine, AND is sticking with the present tranny, then us tahoe owners will never get into the 20's for mileage. Unless of course we stick to 55mph. I would like to cruise downthe highway at 75-85 and keep the rmp range under 2000 rpm. But you watch your inst mpg drop as soon as you push up the speed, and rpms over 2000.  I personally would like the choice of 3:42 or 3:55 gears and a 5 or 6 speed modern transmission. I don't tow anything, don't go off road, infact I struggle with gravel roads & dirt roads are out of the question. I don't need or want the steeper gears, but thats what we get. I've actually considered a gearvendors overdrive. So wer'e stuck with the gas mileage. And I'm sorry but I can't drive 55! I know...I have a giant blvd crzr that I can't stand gettin dirty, but I think I'm in good company here. Hey GM...are you listening???? new tranny? choice of gears? (in reply to biglg) Post #: 43

I haven't had a chance to get on the highway yet but I sure hope something changes. I wanted the 3.73 for a little peppier pickup but my the wife was all about the gas and it is really her truck so for the speed I'll just strap in the cobra and go for a spin. But I really do hope the milage increases..........also the numbers are from the computer not the actual mileage vs. gallons. I havent had to put gas in it yet and shes resets the trip before i can get to it, but im sure its not that far off. < Message edited by e -- 4/21/2007 4:23:11 PM > _____________________________ 2007 Tahoe LT Clifford Matrix 50.5 Security and Remote Start System GrillCraft SW Grille Custom Installed AllSales Chrome Front Bowtie Removed Rear Gold Bowtie Peripheral iPOD Intergration WeatherTech Floor Liners 24" Giovanna DBL G 55's (in reply to BadgerHoe) Post #: 44

I'm not buyin the theory that higher rpms are gonna give you better gas mileage. Perhaps its tied to the small V8 working harder all the time, no grunt, like you might get with a 5.7 or larger?? who knows Every single new Chevy truck I have had - 94, 97, 99 pickups would get pretty good mileage if you kept the rpm's down under 2000 on the hwy.  The new style 99 I had would run 21-22 mpg on the hwy. My 01,03,07 tahoes have never come close to what the pickups would get. What a dissapointment it was to go to a Tahoe getting 16 on a good day.     I know this all depends on driver habits etc, but c'mon, how many people are using these things for "baby carriages", or single maybe two occupants at a time? And another thing, trust me, stuff a few tanks of corn gas in and see what you get around town. I ran it in my '03 and finally quit using the junk when it was averaging 7 mpg around town. The whole point is, these are never gonna be gas misers, I would just like the choice of gears.... not everybody is using these for tow rigs. (in reply to biglg) Post #: 46
