I have a 1995 Regular Cab 4x4 S-10 with 175,000 miles on it.
I bought it used about 2 months ago and put a 2" body lift in it right away so I dont know what the mileage was before that.

I have checked the mileage 3 times and come up with 13mpg, 14mpg, and 12mpg I think it should get better gas mileage than that. Has anybody done any little things that will up the gas mileage because gas isnt very cheap :mad: .

THANKS!!!

Look at the top of this forum section; there's a sticky topic on how to save gas.

Um, lets see.... A truck, a 4WD truck, a raised 4WD truck and a very tired 4.3L.... and 14mpg average... and your point is????

Sorry for the sarcasm.... but realistically I don't think your gonna do much better than what you've got... ultimately it depends on how you drive and where (local or highway).

The ol' girl, even on her best day, ain't gonna be no mileage queen. All that ground clearance is great in the boonies but having all that air blowin' under her belly is just gonna make drag.... and then you raised it another 2 inches. Those All Terrain tires are also not found in the halls of the mileage champs, especially those super gumbo mudders you probably laced up to go along with that 2 inch lift; the open, aggressive tread has a much higher rolling resistance than a normal highway tire. Then you throw in the parasitic losses in HP eaten up by a transfer case.... you see my point?

What can you do? First thing: How 'bout you run a compression check on the engine and find out if the ol' beast can still squeeze out some HP. If the engine compression is way down all across the board, then the only thing gonna bring back your mileage is a rebuilt motor. Likewise any really low cylinder readings are gonna mean teardown time. Next, a *thorough* tune up to include every filter you can find, especially the fuel filter.... use stock AC Delco plugs... a new set of wires.... slip in a new EGR valve, a new O2 sensor and a high flow cat. If it's got the CPI take it in and have a professional fuel injector cleaing done; if it's got the TBI, consider having it rebuilt. Replace every rubber vacuum line (most are hard plastic but have rubber connection points... check them for leaks, cracks etc).... lower the truck to stock height.

Thing is, you could do all this stuff.... spend a boat load of cash and maybe only get another 1 or 2 mpg out of her.... and that includes rebuilding the engine.

I have a '00 4WD Jeep Cherokee w/70K on the 4.0L I-6; if I baby the daylights out her and don't use the A/C I can squeak 17mpg and that's with a good dose of highway driving too. Around town, stop and go, I'd be down in the 14 or 15 mpg range. I've got a hi-flo air filter and a DynoMax cat back system, tuned her up and had an injector cleaning done. I'm running Bridgestone AT tires in a stock size and she sits at stock height.

Hope this helps a little.....

It has regular stock tires on it.

About 2 weeks ago I changed the Air Filter and Oil and put new spark plugs in it and it went up to 16-17 MPG

The plugs must have been really shot b/c when i took them out 1 of em broke in half (i didnt drop it either lol, it was broke when i took it out of the socket).

From 12 to 17 = Not too bad!!!

It's pretty easy to brake a plug while taking it out without knowing it.
We should really have at least 1 spare or access to 1 whenever we pull any.

Personally I'm ticked at my Blazers mileage, and am looking into 2 different options.
1. Save up for a Jeep with their new Diesel motor.
2. Just buy a Diesel engine and drivetrain that I can adapt and install it.
The conversion is a lot of work, but for less than $5,000 I should have a much more affordable ride with lots of stump pulling torque
