Only if we know how big your tank is. Then to get a rough estimate, multiply the gallons in your tank by .75. Then divide the miles by the resulting number of gallons used.
Or mathematically, m/.75(t)
m=miles traveled, t=gallons in a tank.
This will only be a rough estimate, as the the fuel gauge isn't that accurate.

 

its a 20 gallon

 

so I'm only getting about 14-17 mpg.

 

the figures run it at 14.7333333333333333333333333333333333mpg. Asumming it is exactly 15 gallons used.

 

Is there something wrong with your truck? I shouldn't be getting better mileage than you the way I drive.

 

Yea thats pretty bad. To calculate I fill up and reset the mileage counter. Then when its empty and I fill up and see how many gallons I used compared to how many miles i did, divide and weep.

 

I drive around a lot in the city late at night with my friends. (they are street racers and it's a battle to keep up with camaro's, T/A's,cobalts and probe GT's)

 

You have a hard time keeping up with cobalts and probes?

 

If it's a SS Cobalt i understand why, but normal ones? My grandmother got a rental one when her 4.0 Explorer was in the shop. Said it was the slowest POS she had ever driven in her life.

If you want to race buy a SN95 Mustang. I wouldnt be beating the **** out of my daily.

 

the cobalt is a special order car that makes 173 horse and the probe is a v6

 

The probe is still slow. And 173hp in a cobalt is slow.

 

my truck only puts out 100 hp

 

My 08 4 cyl automatic with 4:10's gets around 20-21 with an even mix of city-highway driving.
Hey, FX2.3, how did you lower your Ranger? I'm looking to drop 1 1/2 to 2" in front, add sway bars and maybe build an air dam.

 

Actually they're fast if you're trying to keep up in a 93-97 Lima. Even my family's 125 hp Accord is a good bit quicker than my truck. It's all your reference frame.

 

I got an average of 19-20mpg last night in mixed driving.

 

i get about 300 to 360 depending on how windy it is that week and where i drive but i usally use 18 gallons and then fill up....... and my truck is a snail lol i have to floor it to get to each gear then when im up to speed i can let out and criuse lol.....

john you are the exception lol i think you get so good on gas is your lowered and got a roll pan instead of a back bupmer and your single cab and 5 speed if you was stock with a 5 speed i think you would be average.......

i dont know tho you seem like you dont floor it to often lol you baby it......

 

Just ask anybody whose seen me drive or ridden with me........"Baby it" is not in my vocabulary! I got good mileage when I was lowered and still had the bumper. Actually, losing the bumper didn't change my mileage at all. All in all, I think my theory on going faster is what makes the difference. I believe in cutting out as much parasitic loss as possible to free up the most power. So, synthetic lubricants throughout, free flowing exhaust and intake. The hard bed cover has helped the highway mileage the most. Now I am tuned to run premium fuel only, which gave me a very noticeable bump in power, but hasn't affected my mileage at all, except that I floor it a bit more now cause it's more fun ! Still averaging between 27 and 28mpg.

 

Just curious, do you have an underdrive pulley and e-fan? I have a similar mindset as you about efficiency lol, and those were a couple I was thinking of doing.

 

Haven't found an under drive pulley for the duratec that I am comfortable with the quality on, and I just have to get the e-fan installed, it's hanging on the wall in the garage.

 

23 mpg city, 29 hwy

 

Just did my first fill today since I got the truck 2 weeks ago. Truck only has 425 miles, and I got 24 MPG on it. (mixed driving on it)

 

I have a scan gauge, and we went to my home town (35 miles one way), and my ranger did 34.7 today on round trip..

Set cruise on, 58 mph, rolling country hills/road.

 

I went to Winona to see my aunt, and stock up on my bottled Coca Cola, and the trip is about 50 miles one way.

I got about 26 MPG on I-90 cruise at 72mph.

I think I am going to stay on the main two lane highway going 57 mph to get my 34 MPG.

 

its odd i used to get about 380 miles out of my 20 gallon tank with my old 205/70/14's and now i get 340 on my new 225/60/16's .. should my mpg have dropped that much?

 

Wider tire, more rotating mass, and I'm assuming a higher performance stickier tire could all be a factor.
