Gas Mileage?
I have a 1988 B2 2WD 2.9L. JW what you guys got on gas miilage?
Tell me if im doing this right.
I put 22.69 gallons in it, and zeroed out that mileage. Im right about half way on the gas gauge with 150 miles on it. That roughly means about 300 miles to a tank. Give or take.
Dont i take 300 and divide that by 22.69? If thats right, that means i only get about 13 miles to the gallon.
I do have a bad tranny (does that make a diff?). But im saving up to get it re-bulit real soon. Motor is in real great shape. But other then that, its a great truck/suv.
Does that sound right to you guys?
Oh and any suggestions on improving it would be greatly apperciated.
Thanks

Yes, divide the miles by the gallons of gas used to get miles per gallon.
I don't trust gauges for precision, you really need to fill it up and see how many gallons it took. Normally "E" isn't quite empty, there's a gallon or two at least below that.

What I usually do is zero out the trip odometer at fill-up and write down mileage and divide by gallons to fill.... and I usually fill to the point where I'm one or two short pumps to "top-off". The only true way to get mpg is to start with a bone dry tank and zero out the trip meter and fill it up all the way and drive until the tank is bone dry, but my method usually gets you pretty close. You can't judge on an in-between fill-up mileage reading, as mikebon said. Ford fuel gages are notorious for being inaccurate, especially older vehicles.

When I run my 2.9L Ranger, my gas gauge usually sits about halfway to E at 150 miles, so that sounds about par with my truck. But I also fill it up when I reach around 200-240 miles, and I average about 11 gallons each time I fill up.

I got a 88 bronco II, and am averaging 14.7 mpg, but not sure how accurate it is, it is suppose to have 195 / 75 / R15 tires, and it has 235 / 75 / R15. I think I am accually gettin better milage than that.

Mine too. Although it is a recent phenomenon. Is this the sending unit in the tank? It only used to dive at 1/4 tank and then bounce up to 1/8th. Then I knew it was really empty.
I get between 17 and 20 mpg (imp gallons). Mostly depending on the state of the tune up. I have an automatic and run 235/75R15.
Sorry if I hijacked the thread.

fill your tank and zero out milage. when you fill next note how many gallons it took to fill, divide into miles it took to get you to that point and you will know exactly.... Almost (As theoretically the more gallons you have weighing you down, the poorer the milage, not to mention load, tires, tune and so on). If you write down gallons (As close to empty as you dare get) and zero milage every time you will develope your most accurate running average.
full tank (miles zeroed) = a
Miles driven =b
next fill amount (Gallons) = c
exact milage = d
so, b/c=d and (b/c=d)*a = total assumed milage per tank

The tank holds 23 gallons, and on average, on a good run, I can usually get 375-425 miles between fill-ups per tank... and that's running it down to almost E and hoping it doesn't die on me getting to the gas station haha.

I remember one time me and my neighbor went into town in his 79 Chevy. We just pulled up to the pump and he says "alright, that's it."
"what's it?"
"we just ran out of gas."
"i thought you shut it off."
"no i didn't the key's still on. the motor just died."
Good timing.

I'm glad this question has arisen, as I was going to ask what a good average mileage would be for an '87 B2 with 2.9L and 5sp manual. Having only just bought mine a few weeks ago I haven't had a chance to work out what I'm getting yet.
Just filling a small tank over here is depressing, with regular unleaded currently running at the equivalent of about $6.90 per gallon.
