I have a 99 mazda b2500 2wd 5spd and I can only get roughly 250 miles to the tank. Everything seems good when I check it or clean it. Running out of ideas. Truck only has 92k on it. I've replaced filters, spark plugs and wires, after cat o2 sensor, dpfe sensor, cleaned the maf Etc.

 

How many gallons of gas does it take to fill it up after doing 250 miles?

 

between 10 gal. And 12 gal

 

12 Gal = 20.83 mpg

10 Gal = 25 mpg

You have a 17 gallon tank, so at 20 mpg = 340 miles, so you can easily go to 300 miles before filling up.

When my gauge reads empty I still have 60 miles I can safely go.

 

so in good terms my trucks good?

 

I think it is, others may say differently.

 

+1 ^^^

Depending on your driving conditions 21-24MPG is about right for a 1999 2.5l Lima engine

Short trips kill MPG because choke is on, yes fuel injected engines are still "choked" for cold running
Best MPG happens after 10minutes of driving, engine warmed up, and at a steady speed

You have a manual so keep RPMs above 1,800 unless stopped, under that and you will be lugging the engine, so out of the power band and wasting fuel

Make sure tires are inflated to spec. under inflated causes lower MPG


You can install a Vacuum gauge in the cab, best MPG happens at the highest Vacuum you can maintain at speed, not at idle, thats 0mpg, lol

 

Mine (1994 2.3L Man.) gets around 26 MPG, 400 miles total on a full tank (15 gallons). Mainly highway driving.
