I am getting approximately 10 MPG in my 1994 GMC Sonoma. It is a V6, 4.3l. I took it to a car shop and he said it looks like it has had a recent tune-up - I bought it about a month ago. He suggested a BG...
To tell you the truth, you aren't far off from normal, depending on what kind of driving you are doing. I have owned 3 of these and they all average 12MPG around town. Driving habits have a lot of effect too.
your tires properly inflated, and check them frequently.1
your front suspension and steering in proper alignment.
the thinnest viscosity oil that your car's manufacturer recommends (5W-30 for
most newer cars).
your engine in proper mechanical condition.
your engine in tune and make sure the air and fuel filters are clean.
sure your brakes are not dragging.
body damage. That crunched front fender adds aerodynamic drag - just ask any
race car driver.
use premium fuel if your car does not require it (check your owner's manual);
using it is an unnecessary expense.
waste your money on those late night "as seen on TV" products that
are supposed to increase your mileage.
excessive warm-up time. Modern engines do not require it.
idle your engine for long periods. Turn off your engine when you leave the car
or have to wait a long time.
your speed at 55 miles per hour or less whenever possible.
newer vehicles with aerodynamic designs, close the windows and turn on the A/C
when driving on the freeway.
older cars with inefficient A/C compressors, use the ventilation system and
close the windows, temperature permitting.
merging traffic and stoplights - decelerate and accelerate smoothly.
your trips wisely. If you need to go several places, plan a route that allows
you to run most or all of your errands in one outing.
the trunk! Extra clothes, overdue library books, tools and the bag of aluminum
cans that you have been meaning to take to the recycler all weigh down your car
pool whenever possible or practical.
to radio reports for alternate routes around congested areas.
in the highest gear possible (without lugging the engine).
to keep your speed constant. Use cruise control when on long stretches of road.
According to the
U.S. Department of Energy, nearly four million gallons of gasoline could be
saved nationwide each day for every one pound per square inch (psi) of tire
under-inflation, compared to the mileage if ALL vehicle tires were kept
inflated to the manufacturer's recommended pressure.
Department of Energy estimates that for 145 million passenger vehicles idling
five minutes per day, approximately four million gallons of gasoline are
consumed without going anywhere.
According to the
U.S. Environmental Protection Agency and Oak Ridge National Laboratory, a
vehicle loses about one percent in fuel economy for every one mile per hour
above 55 m.p.h. that it is driven. A passenger car that averages 30 miles per
gallon at 55 m.p.h. could typically get 28.5 m.p.g. at 60 m.p.h., 27 m.p.g. at
65 m.p.h. and 25.5 m.p.g. at 70 m.p.h. Remember, however, that for different
speeds, the changes in fuel economy will vary by vehicle model.
Each 100 pounds
of needless weight will cost up to one-half mile per gallon, on the average.
