Most people say, don't drive too fast, when asked, how do you save on gas mileage?
That's the extent of knowledge of many drivers, but in fact, there are several simple things that you can do, to stretch those gas dollars.

"One of the most important is to make sure the spark plugs are firing properly.   Bad plugs will mis-fire, and that gas is wasted," said Steve Johnson, who's worked on cars for 40 years.   He now is employed at Terry Wynter Auto Service in Ft. Myers.   "Also, a clogged, dirty air filter will reduce mileage.   And if your gas cap does not fit properly or is worn, it will allow gas to evaporate from your tank.   That too is costly."

Johnson says a lot of people are asking about gas mileage these days.   He also advises:  keep the tires  properly inflated.   "Low tires drag on the road, and that means, you use more gas to move the car down the pavement," said Johnson.

"Another key area is driving behavior.   The best advice is to accelerate quickly to your speed, and then stay there.  The car burns much more fuel when you are accelerating slowly or braking suddenly.    The best is to get to your speed, stay there, and then coast to  your stop.  That behavior will save gas," said Johnson.

As for weight, Johnson advises, get the junk out of the trunk.   Some experts estimate that 100 extra pounds will reduce mileage by 2 percent.   Also, feel free to run the air conditioning.   Rolling down the windows creates drag,  that will cost more fuel than running the A/C.    "This is Florida, after all, so I tell people:   feel free to run the A/C, no reason to feel guilty about that," Johnson told WINK.
