man who are these people claiming under 10 mpg!!! they must NOT have a 4.3l!

 

try having your crank position sensor out of whack & not being able to go through the re-learn procedure.... 25 cliks on 1/4 tank! <--- thats painfull!!!

 

man last time i had mileage like that i was driving up a mountain! but on the other hand on the way back down my gauge was reading 0L per 100 km i took a picture because i knew thats the only time i would ever see that

 

I was/am im Winterpeg, you know that & hopefully things go well & all is right in my CB/Blazer world
Horrible last couple weeks I tell ya.

 

my average according my trucks electric mpg gauge is 20.5 after a 200 mile trip driving up driving up a mountain (crystal mountain) and back. at the top it was about 18 and when i got home it was 20.5. so pretty good i think :P

 

I've been watching my mpg for the past few weeks now. With mixed driving highway and interstate I keep coming up with around 12.14 mpg (this has been the lowest) but never higher than 13 unless all interstate I get 15.5mpg. Of course this is with 33X12.5 mud terrain tires and only 342 gears. I do a lot of trailering too. I remember the days I used to get 22mpg on the interstate before it was lifted

 

THATS the only thing holding me back from putting bigger tires and a bigger lift on it. I put WAY to many highway km on it to put a higher lift. When i get another car for highway and what not the blazer will get its lift.

 

wow, thats like having 3.01 gearing, probly never shifts into overdrive and may be lugging even in 3rd. 4.10 gears would help that somewhat, but you would still have the weight/mass of those huge tires.

 

Yah it's killer sometimes. It still tows pretty descent though on the interstate. I tow my boat which is around 2500 maybe a little less and it pulls it along pretty good for the mismatched gears. I plan to regear soon I should of done it in the first place because I do almost 15k of driving a year. 410 gears will help so much though I'm pretty excited for it

 

My mileage has hardly changed since I bought my 99 4wd LT in 2000. 18 avg mpg and about 21 highway. I don't dare calculate my mileage when I'm towing my boat or I'd stop towing my boat. Don't have any idea what my gear ratio is but it's whatever was stock. Never been off road with it and use passenger tires. Haven't seen snow since 2003 and only use 4wd if I have trouble pulling my boat out of the water on a steep ramp.
