So heres my idea for what i want to do to my blazer.
Goal: To have it look good and perform well. I would like to achieve better gas mileage, and not spend a lot of money overall

What I want:
Airaid Air intake kit 148
Go Rhino Sumatra 3000 step guard black 207
KC Hilites 2x6 all season lights 88
KC hilites Quad beam conversion 14
Hella/optilux 1400 series 20
LUND window deflectors 38
TOTAL COST: $509

What else could I do to get better gas mileage? (Im getting about 15)

 

dont slam the gas at redlights is the big one.

I eased on the gas from stops and i got up to 21mpg compaired to my normal 16

 

what is the average mpg on the 4.3l?? i think something is wrong with my ride because i only get like 220 miles from full to empty....i do have my service light on but had it checked and no biggy it's some evap thing.....i'd like to know what i'm doing wrong to be only getting like 12-13ish miles a gallon

 

you aren't doing anything wrong. . these truck like gas like a fish likes water...... swap mufflers.... if you can keep from hot-rodding your truck just to hear the exhaust, it will get you better mileage. . .

 

yea i ran the **** outta my truck last night at the races and all and my milage droppe to 18.6mpg

Now im gonna ease on the gas all week and get that back up in the 20's lol

 

If you are getting 220 miles per tank, then you're getting around 17 MPG....these only have a 13 gallon tank....so even if you ran it completely dry (out of gas) from a completely full tank then: 220/13=16.92 MPG. which is probably about average for these.....I drive primarilly on highway(55 MPH) and get between 20 and 23 MPG, but I NEVER put my foot into the pedal. That's what my other car's for

 

13 gallon?

I filled up with 16.539 gallons yesterday on the pump.................

 

Really?........maybe the 2-doors have a bigger tank......if so sorry for the mis-info guys. I know my 4-door has a 13 gallon tank, but the 2-door's tank is behind the rear axle so they probably do have a 16-18 gallon capacity.

 

Well can someone verify gas tank size or are they different. I could have swore I read in my manual my 02 4 door has a 17 gallon tank.....maybe i'm wrong, normally I am

 

im thinking its 17 for mine cause i stared at the gas pump lol
