miles to a tank of gas

[matt351]

What should a good running 4.0 sohc get to a tank of gas? I've got 265/75r16 BF Goodrich A/T's with a torsion crank up front and shackles in back. I've got a couple of cel's, but it still seems to run just fine. The last tank I filled to the brim and got 400 miles to the tank. Just wondering if I should be doing better than that?

Thoughts?

Sounds about right for highway driving.

You meant a couple of trouble codes. What numbers? Agree with Bobmbx, 400 miles
(17.8 MPG) with a 22.5 gallon tank is decent, especially if you are using ethanol gas.

My Ex holds 20.8 gallons (per the manual) and per my UltraGauge gets 18.6mpg in city driving. That yields me exactly 386.88 miles when completely topped off.
When highway driving only I'm getting 22.5mpg for a tank range of 468 miles. I'm running Goodyear 235/75R/15's.

Sounds real good, which axle do you have?

I'm not in the truck right now to look, but I started a thread about a week ago about the trouble codes. I think they are about a vac leak. They mentioned the truck running lean. As for gear ratio, I've got 4.10's which I'm sure probably don't help much lol. When I bought the truck a year ago it had 4 mismatched 235/70r16 on it and I got like 475+ to a tank of gas driving out to Kansas City. When the time comes I'm going to buy some 235/85r16's in hopes of getting a few more mpg's out of this thing. I do lots of driving for work, so I'm trying to get every mpg I can from this while still keeping it comfy and reliable.

it depends on what size tank you have. 17G or 20.5G (i believe it's stamped into the rear of the tank). the last 1.5-2 gallons isn't really useable because the fuel pump pickup is located in the rear part of the tank, so if your headed down hill you'll run out of gas. of course it also depends on what your typical MPG is. this time of year my 5.0L's get around 16 MPG around town and maybe 23-24 MPG (the AWD gets about 1 MPG less) cruising on flat hwy at around 55 MPH. your mileage can differ greatly depending on how and where you drive.

the SOHC V6 get's about the same MPG as the V8. maybe 1-1.5 MPG better.

Have you re-calibrated the speedometer for the larger tires? If you're truly knocking down mid-17's for MPG on ethanol and larger tires, that's very good. I run non-ethanol and usually gain about 1-2 mpg on my commute in my '02 V8 4x4 vs ethanol blend.

OE tire size for your 2000EB is 235/75-15 (28.9") for 2WD and 255/70-16 (30.1") for 4WD. Check your door pillar sticker to confirm. Using a larger diameter tire may increase highway MPG but that may be offset by reduced low end torque and the engine not operating at optimum efficiency and RPM range. Your speedometer will also read slower than actual speed. Most of the on line tire calculator sites recommend no more than a 2.5% overall diameter difference. I find the biggest MPG killer for these bricks is accelerating from stops.

My 99 sport AWD v6 ohv with 4:10 gears and 16(16.7 i think is exact amount)gallon tank and 265/75/16 is like 300miles I think. It eats gas on highways because of higher rev at 2k rpm and city driving it gets better gas mileage because its only at 1,500rpm. Higher the rev the less mpg. I avoid the 55mph and 65mph ways because it eats up gas at those rpms

 

[matt351]

According to my GPS and those speedometer things the state police set up my speedo is spot on. Is there a way to find out what gas stations locally run non ethanol gasoline as opposed to ethanol blends?

I don't believe 2wd or 4wd is the defining factor for tire/wheel size. My 2WD '01 EB and my 2WD '00 XLT both have 16" wheels and 255/70 tires, while my AWD Mountaineer has 15" wheels. I don't know if having the towing package is what determines what size wheels you get (both my EB and the XLT have the towing package) or if it was just and option.

Interesting. My '98 SOHC 4x with the towing package originally came with P225/70r/15's off the lot. With the first set of new tires I originally went with 235/75r/15 Mich LTX AT's thinking I needed them. But more road noise and I really didn't need AT's. I've been running P235/75r/15's for years now - no complaints.

My used XLT came with a brand new set of 255/70 16" Fuzion tires (never heard of them). They are tall (look taller than the same size Michelins on my EB) and look good, filling the wheel wells, but they are really noisy. Not sure why they drone so much, which is mostly noticeable at speeds under 50 mph, as the tread pattern is not that aggressive.
