This van is a 1993 with 140,000 miles which I just bought it seems to run very
well but no gas millage. I have no knowledge of recent work or any records but
I have another 1993 van with same motor that I have driven since 1996 which is
getting the same 10 miles per gallon and I use to get 15 all the time until it
went south on me. I bought the first van as a back up and I intend selling the
second unit as soon as I have some current problems repaired. I have driven
several van's with 302/351 engines and always had great luck getting the 15
miles per gallon or there abouts.
I plan on changing plugs / I have always used motorcraft would bosch
give me more miles ?
bellows air filter
carb gasket and clean
idle air valve and clean
I appreciate your responding!
Carb ????? isn`t it fuel injected, and stick with the motorcraft
plugs, if it is injected, replacing the oxygen sensor can often help.
unfortunatly the gas we get now is crap and getting that 15 back short of
only driving 55 all the time is going to be tough. also have you done a
comp test to make sure the eng is in sound shape to begin with? KB
SOME of what you are seeing with the poor mileage is the crap-gas they blend
now that is part corn. There is almost nothing good about ethanol beyond the
fact that they can make more of it. Sadly, making it in the first place is
not really a very good deal, as you are finding out. The energy is less than
gasoline, it takes 25+ gallons of water to make a gallon of ethanol, and the
diversion of corn away from the food chain is causing the price of food to
Of course, you are driving a brick, and that's part of it too. But the brick
has always been a brick, so not much has changed there.
We need more information.
If your trips are short, then you are always driving the car in a condition
where the fuel mixture is rich. If you are driving short distances, then it
is not on the freeway, it is at traffic lights. Since you spend a lot of
your driving time at a red light, your mileage will suck. Then, you hit the
gas, and your mileage sucks. All of your driving is in the worst possible
driving environment -- you are either getting up to speed or you are sitting
at red lights, and you are doing this all on a cold engine that never gets
up to full temp.
If you are stopped at a red light, you get zero mpg for several minutes.
If you are always working for the best 1/4-mile times you can get, you get
horrible gas mileage, although it is better than zero.
If you like the noise of high RPMs, and don't shift to the next gear until
the howls and complaints make your ears hurt, you will get horrible MPG.
To get the best MPG, you want to shift early and often. You want to take
your time getting off the line, and you want to hit 2nd before you get to
the crosswalk on the other side of the intersection. If the light you are
apporaching, lift off the gas and coast. You should time your arrival at the
red light so that it is green by the time you get there. It takes far less
gas to keep the car rolling than to get it rolling again after it stops.
Put some air in the tires. Under inflated tires takes lots of gas. You
should read the tire placard on the driver side door jamb, but generally
speaking passenger car tires take about 33 pounds of air, if you have less
than 30, you will use more gas. Too little air makes the tires wear on the
outside edges, too much air makes them wear in the center.
