My '97 Blazer 4x4, 4.3L, gets 15 city and 17-18 highway. I drive a little agressive around town, and typically 65-70 on the highway.

What's your gas mileage?

I get roughly 320 miles on a full tank in my 2000 Blazer with 4.3. Sucks compared to the 97 S10 2.0 I used to have. But tons better than the 91 Camaro 5.0 I used to have before that!!

virtually the same with my '98 4x4 4.3

We get about the same

There's a good web site (I've attached the link) which has pretty reliable economy info.

I've only figured mine once. Last year I drove from Missouri to Florida and averaged 20 mpg. I wasn't expecting that good of mpg especially with with a bunch of luggage and my gf with me. As a general rule of thumb you lose about 1 mpg for every extra 100 lbs. in your vehicle.

I think I'd be lucky if I got like 250 to a full tank, 320 sounds really good, but I do a hell of a lot of intercity driving. Has anyone here every tried this stuff called "Seafoam"? I hear it really improves idle and gas mileage.

Anyone ever try those Turbinator products? You know, the passive device you put behind the air filter (and between the TB) which is suppose to swirl the air around and give you better gas mileage? ...And please if you sell these things, don't reply. They claim 30% more HP and gas mileage.

I've heard stories about these things breaking apart and going into the engine.

My '95 "W" CPI porks out an abysmal, but par for the course 13~16 MPG City, 22 to nearly 25 on the highway depending on temperature. Those early moring, 20 degree days I usually start the truck and let it idle until the needle moves 2 tics up from a flat 100 before driving off. I like my boots warm, but the idle time eats up fuel economy.

I have a 95 blazer LT, usually get 13.5-15.5 city depending on the weather.. about 235mi to the tank when i decide to fill it up which is usually takes 16 gals. i still dont know how big my gas tank is so i dont want to run it complete dry

On your model year - same as mine; 4 door 4x4 carries 19 gallons.
2 door 4x4 carries 20 gallons. I figure that they shave one corner off and a bit of volume as a consequence of the slightly different body geometry for the 4 door model.

How many gallons does the 4 dr, 2wd 2000 Blazer hold?

15 town 20 highway 91 s10 blazer

16-18 in the city but i have gotten upto 20 mpg

20 city 26 highway (pretty good Chevy says 18/25) I lay into pretty hard sometimes but usually take it easy. The Impala is for raising Hell.

98 4wd 4 door 118,000

I just checked mine after running a bottle of Amsoil P.I. through my 99 Blazer LS 4.3L 4x4. I am getting 19+ miles per gallon or 300+ miles per tank.

This truck has 156,000 miles on it, does not burn any oil, runs like a top and is purely stock...but well maintained. That's with petroleum based oil, cleaned out EGR valve, and a steady freeway driving....typically 70+ miles per day on the freeway.....I'd say that's great for a 4350 pound truck...

for the last 2000miles my average is 15.1. Highest 19, lowest 11.

94 4.3L Vortec, 4x4 4dr

94 S-10 4X4 4 door with the bullet proof 4.3 with 203,000 miles, average around 20.

Scam, does nothing on a vortec.

Your heads already swirl the air hence the VORTEC name.

On topic, I get:

Summer:

18 city / 24highway

Winter

15 city / 19 highway

125,000 miles on engine

I have a 94 s-10 blazer that gets about 22 mpg city and 27 hwy

4x4?

How are you calculating the economy?

I have virtually the same numbers, my economy is definetely not as high in the cold. Hauling stuff makes a big difference too (like my 200lb moped and speakerbox).

I get no better than 21 mpg on the highway at about 70 mph. I do a mixed city highway commute of 30 miles each way every day for work and get a consistent 18-19 mpg, unless it is real cold.


I would have thought that the pure highway would have been better by a few -- o well.

85 s10 blazer 4x2
8-10 mpg city
12-13 highway
sbc 350, headers, intake, large cam, geardrive, 750 carb with large jets th350 trans. runs 8s in quarter mile. it is a show and go. and believe it or not, even with the price of gas, its a daily driver.

I have used "seafoam" and I like it seems to do something,I dont know...I know Blazer LT dont like the stuff but hey I used it and it was a noticeable change. Lots of cool insect killing fog also,I mean lots....LOTS!!!!!!

LOL

12mpg city...18-19 highway 1995 LS 4x4

I get about 280 Per Tank, I don't let it completely get Empty, Cuz I don't Want the Fuel Injectors to get clogged up with the shit that's at the bottom of the tank, but 280 no matter if I'm in the City or Highway. Okay, maybe sometimes I'll get 265-280 in the City. I Don't Tow, or Handle Luggage. I carry family around a lot though. Brother in Wheelchair and mom. Wheelchair is light, and he's starting to use crutches now, so the wheelchair weight is non-existant at the moment.

I bought the spiral max for my stock intake to see if they really worked and I am getting two miles more per gallon, but the horsepower wasn't much different, and torque increased a little.
I get 18 in town 21 on the highway, and now I am getting ready to put on a new muffler and we will see how that goes.

They are a scam, proven to LOWER economy and power.

i must agree. if you know the common laws of auto physics, then it only makes sense that if you add more air, it makes your vehicle's computer just automatically add more fuel, and you SHOULD get more power, but you WILL FOR SURE lose your economy. i noticed a immediate drop in my MPG from 32 to 28 when i added a cold air intake on my cavalier. and thats even when i tried my hardest to get the best mpg. and a little word of advice for you people with stick shifts for better MPG, you should not shift to soon, especially in any vehicle without efi or newer. the stress you add on your car to move it at rpms too low causes more fuel to burn then when the momentum of your cars engine is helping push it along at higher rpms. now im not saying more than 3500rpms on any vehicle, unless its dohc then maybe 4000rpms, but for sure dont shift until your rpms reach 3000. just try it and youll be amazed at your fuel economy. let your vehicles lower gears get you better gas mileage. and if you dont belive me, dont you notice yourself pushing the gas harder and farther to accellerate your vehicle just as fast in 5th gear as you would 3rd or 4th. your just wasting fuel. some vehicles now, especially the newest ones, have electronic thorottle control which will not care how far you push the pedal, itll do what it can do at the given time.

All I can say is that on the dyno horsepower was about the same, and torque was a little better, but my gas mileage improved alot. So the 60 dollars was worth it for me. 1996 2 door LS

Proof of a dyno sheet would be good.

If not, I call bullshit.

Nah, a cold air intake will not affect fuel economy.

Having your engine getting the air it needs it good for proper power production and therefore less of a need to push the go pedal as much.

I gained 3MPG with my intake.
