mileage, fuel gauge problems
Anyway, I have the same problem about the large tank and only being able to put a smaller amount in the tank. I have the 2000 Blazer with four doors, so my tank should be 18 gal according to Mitchell On Demand. The most that I've ever put in was 16 gal.
Now my fuel gauge on the dash is messing up. Sometimes when parked it goes from empty to fully full, and sometimes it messes around near where it should be. All three conditions during a warm-up period. If anyone that reads this has suggestions about where I should start with that problem, good on ya, let me know where to look!

Sending units are notoriously unreliable on these things. Before swapping that out, check all the wiring first.
If you're gonna drop the tank to replace the sender, might as well replace the entire assembly, because the fuel pump is just as "reliable".

1997 Chevy Blazer LS 4x4 4.3L Vortec. Driven in 2wd. Driving habits are slow acceleration compared to most aggressive drivers on the road, I'm the guy that most people either ride my bumper or overtake. Mostly city miles, with an exception of about 40 miles highway at 70 mph (fast for me; Typically I keep it between 55-60 mph). Weather in Ohio at this time is about 50 degrees on average. I'm experiencing about 18 mpg.

I have the same truck (a '98) and same driving habits with about the same results. I've monitored mileage over the years and consider my Blazer to be basically a 20mpg vehicle, averaging about 21/22mpg on the hwy, 17/18 in town. (In response to an earlier post, my low fuel light also comes on with 5 or 6 gallons left in the tank.)

I just bought a 1999 Blazer LT 4WD. I haven't done a tune up yet, but I did change the air filter and put on some new tires (235/75R15, apparently Michelin doesn't make the spec 70s any longer). According to my aCar app, I'm getting about 13.8 MPG on the first two fill ups. I plan on going through a few tanks, and then doing a tune up.
I like the press the gas.
