Nine ways to save gas and money this summer

Gas costs have become an unnerving new concern when planning vacations. An increase of about a dollar per gallon in the past two years, or around 30-35 percent, is no minor addition to the already often considerable expense of traveling.

It's not a problem that is likely to go away. While we may see a leveling off of average prices, most experts don't expect prices to go down very much in the future. The fact is, the days of the $2 and under gallon of gas are almost certainly over -- but we've managed to come up with a few ways to save at the pump.

Simple stuff
1) Buy gas the day before you travel. You already know where the best gas deals are near your house or office, so you might as well purchase the first tank of your trip at a price you know and can control.

2) Empty out your ride. Leaving the 50-pound bag of dog food, the sack of grass seed, the immovable box of magazines headed for recycling, and more in your car on long trips adds weight to your car and gobbles up fuel at a rate of 1-2 percent per 100 pounds. Lighten your load before traveling to save money.

On the highways
3) Choose an exit with several gas stations. You can usually tell these from the amenity signs on the highway leading up to the exit -- the ones that list several fast food joints, local diners, hotels and gas stations. If the sign lists two or more stations, you will often benefit from the simple fact that there is competition for your business.

A sign will typically read:
Brand A - 0.1 mi -->
Brand B - 0.1 mi <--
Brand C - 0.8 mi -->

In this case, you may want to choose the station that is furthest from the exit ramp.

Typically, Brand C will have the lowest prices, simply due to the inability to gouge outsiders looking for a quick off-and-on fill-up (the locals often use this station).

Two things happen. First, it's cheaper. Second, it is often less crowded. The extra mile's drive will cost you about 10 cents, but you can sometimes recover that in the first few gallons, and ultimately save quite a bit if you are running on empty and fill your tank.

4) Use "official" rest stops -- like those named after founding fathers, football coaches, nurses, mythical figures and others surely lost to memory were it not for Wikipedia and New Jersey Turnpike rest areas. (Quick -- who was Joyce Kilmer? Anyone? Anyone?) Oddly enough, these official rest stops tend to have fairly competitive prices; perhaps it would be unseemly for a station enjoying the considerable benefits of a government highway contract to soak us with high gas prices while trapped on the costly side of toll booths.

When renting a car
Anyone who has filled the tank of their rental car at the station just outside the cluster of car rental companies knows that you can get truly soaked by waiting until the last minute. These folks know they are your Last Chance Texaco, and price-gouge accordingly.

5) There are a couple ways to win this game. Your most reliable tactic is to check nearby gas prices on your way out of the airport/car rental zone just after you pick up the car -- this is when you should be thinking about saving money, not when you are returning the car and are under time pressure to make a flight. Then, when returning the car, consider purchasing your gas some distance from the rental return counter.
