1988 E250 Extended Club Wagon W/351 EFI, C6 auto & 3.50 rear. Stock with a slightly modified exhaust.
10 mpg towing a trailer with a race car on hwy.
12-13 hwy non-towing on hwy.
Don't know city, don't drive it there much.
P.S. - mpg may be better then it appears as the tires are oversize (bigger then stock) and the odometer is under reporting miles driven.

87 e350 6.9, c6, 3.54, 235/85r16, all stock, weighs 8000lbs when not towing or hauling extra loads
gets 16.5 when i'm driving nice, as low as 12 when towing and being aggressive together.
totally stock, 30k on engine rebuild, planning for a GV overdrive and a turbo, should easily put me over 20, and for a guy who is lined up to spend over $10k on fuel this year, its well worth the investment!

The overall gearing in our vans is almost identical and my van is 10 years newer which could make a difference in emissions and resulting fuel economy. There are a whole lot of variables at play here beyond the tires to just conclude that the tire size is the issue, if there even is an issue. Although I think that a lower rolling resistance tire would improve the fuel economy somewhat.

I want lower gears, would love a 3:73 as the 3:50 is too high for my weight, your choice in tire size is bringing you close to 3:50 gears, it's too high, that's why the factory put in what you have. Hwy vans have 215/80 tires on them, the same diameter as my 245/75, but narrow, I prefer the width for stability because the tires are tall and vans are top heavy, guess which tires were on roll over vans.
Yeah, saying fuel economy is likely lost due to your van's age, you are absolutely right, yet my van is 6 years older than your and heavier with the same results, you may want to lose the lift and drop the tire size to stock.

I meant that my newer van could possibly be meeting a higher emisions standard and as a result get poorer fuel economy. Pure speculation on my part. I'm actually content with my MPG's and live the way my van looks. All beefy and tough. But if a set of Michelins could make a big enough difference, I might spring for them, in a 235/85 16, gotta have the look.

Kind of messed up but remember, the vans haven't changed, they are still the old 16 valve OHC setup, seems only the trucks change, would be nice to see a 3 or 4 valve in them from the factory. The higher they set, the more air they catch, I'd love to have one with a drop on it, streamline it a little.

Ha, no choice for wheelchair users, the converted mini vans don't get much better mileage, ramp requires more room for entry, and they ain't cheap. I find it comical that the new Econoline has no EPA predicted MPG listed on them, an obvious sign that you best make sure you can afford to feed it before purchase.

02 E350 extended, stock wheels and tires, 75 on last weekend's trip in the pouring rain with about 1000 lbs including a roof rack with gear on it.
14 mpg
Ugh, guess I'm gonna have to slow down or just bite it and buy the gas.
Sure love the drive of the newer van though! Handles like a car!
