So does mine, which is why I have a 4 wd 2006 Trail Blazer.

24 mpg with a 4x4 at 70 mph. OK.

 

Makes me want to change my 74 into my daily driver. I get 30 mpg w/ that. Have not really set my MPG on my blazer due to still working out all the gremlins.

 

Since I bought it (December) Ive almost always gotten 14. A few times Ive gotten as high as 17. Its been pretty cold here lately and we have been getting about 4-8 inches of snow a week lately so Ive had to scrape the windshield and just let it idle while I do it. Ive also been useing 4wd a lot lately since my tires suck in snow.

I have changed the air filter and it was pretty dirty so that should help a little bit. I will replace plugs and wires when it gets nicer out since I dont have a garage to work in.

 

I get 12mpg around town and 14-15 on the highway.

 

I havent put a cap and rotor on but I have replaced my wires and plugs. I replaced the fuel injectors when i bought it in 04.

 

I get a steady 18.2 mpg, at a 75 mph average speed.

 

Hhahaa you got owned by a 1974!!!! 30mpg

 

My 4.3i Blazer consumes 15 Litres per 100km, stock equipment. 75mph average speed.

1 gallon = 3.79 lites = 3.79 EUR = $ 5,05
100km = 62.137 miles = 15 EUR = $ 20,0

=> 16 mpg

that seems okay.

 

92 - 4.3 4WD gets 17-18

88 blazer has a LS1 auto and 4.10 gear with Lock up convertor and OD gets 23 mpg

carbed 355 in the limo S10 truck T400 3.23 rear gears gets 16 by itsself .... but usually 9-10 since its usually connected to the camper or the car trailer.

my other S-seriesvehicle gets gallons per mile when playing ..... but it is fun.

 

I have a 1999 Blazer with 118K miles and new tires. I just made a run from laramie Wyoming to Denver and halfway back to Laramie. All speeds were consistently over 65, with 120 miles of the trip at speeds varying from 65-80 MPH. I had a small set of ski racks mounted on the top rack. Gas mileage carefully calculated from fill-up to fill-up: 20.2 MPG.

Incidentally, this Blazer still has the original plugs, wires, cap and rotor.

That felt good!
