Debunking Some Popular Gas-Saving Myths
The real way to keep your milage high and fuel costs low this summer
The summer road-trip season is here, and according to AAA, consumers can expect to see prices to hover around last summer's high of $3.55 and $3.70 per gallon. Can you have your fun in the sun while avoiding pain at the pump?
Increasingly, newer cars are smashing old gas-saving truisms. For instance, buying a smaller car seems like a reasonable way to achieve higher gas mileage. However, compare a subcompact like the smart fortwo, which gets 38 mpg to a Chevrolet Cruze''s 36 mpg, and it becomes clear that smaller isn't always better. Plus, the Cruze can fit five passengers and contains 15 cubic feet of space, while the ForTwo can only squeeze two passengers in 12 cubic feet of space.
Larger, longer sedans give more room for air to flow smoothly around the car than smaller shorter models, which reduces drag while highway driving.
It was once common knowledge that manual transmissions were more efficient, but improvements to automatic transmission mean the fuel use is now often about the same. The same goes for premium gasoline. Unless a car is specifically designed for high-grade gas, the extra cash per gallon is going to go up in smoke.
If everything you thought you knew about saving money on gas is wrong, then what can you do to cut down on fuel costs this summer? Here are a few tips:
New air filters and regular oil changes are good for your car and wallet. Also, take a look at your tires before any road trip. The Environmental Protection Agency says even a slightly under-inflated tires can cost a car in fuel efficiency. By keeping you tires properly inflated, you can improve your vehicle's gas mileage by up to 3.3 percent, which works out to an equivalent gasoline savings of approximately $0.11 per gallon.
Use Cruise Control
There are times when cruise control isn't appropriate, such as heavy traffic or when climbing hilly roads,
but if you're driving over relatively even terrain, cruise control can prevent unnecessary speed changes which waste gas. Cruise control can also keep drivers from creeping up in speed on long trips, saving you money on gas.
Highway driving is the most efficient way to get around, but speed too much and those savings go out the tailpipe. Fueleconomy.gov estimates each 5 mph over 50 mph is like paying an additional $0.24 per gallon for gas. You don't want to drive too slowly on the highway of course, but keeping your speed around or under 70 mph can save a lot of cash on fuel, not to mention speeding tickets.
Travel light, store right
Excessive weight can ruin fuel efficiency in any car, so it is important to prioritize when packing for a long road trip. How you stow your stuff can also have a major effect on gas bills. Hauling cargo on your roof, for example, increases aerodynamic drag and lowers fuel economy by around 2 percent to 8 percent in city driving and 10 percent to 25 percent at Interstate speeds according to fueleconomy.gov.
