Summer is coming up fast and with it gas prices will be increasing, as they seem to do every year. In order to help you, our dear readers, keep as much of your hard earned money in your wallets and purses this summer, we’ve put together a list of some of the biggest myths about gas saving to take a look at which ones work and which ones don’t. Enjoy.
The first is about the best way to actually save on gas. Many people will offer their own opinion but, in test after test, the best way that’s always been found to decrease gas consumption is simply to slow down. Studies show that, among most cars including hybrids, the change from 55 mph to 65 will reduce fuel economy by 4 to 8 MPG. If you go from 55 mph to 75 it’s like switching from driving a compact car to driving a large SUV the increase is so bad.
How about carrying stuff on the roof of your car? Does that wind drag really bring down your fuel economy that much? In fact, yes. Tests show that even something like an empty bike rack can decrease the cars mileage by 5 miles per gallon and adding to bikes to the top decreases mileage by nearly30%!
Many people will say that if you want to save gas you need to use your car’s AC sparingly. While it’s true that using the AC will decrease your mileage somewhat, the fact is that it’s only between 1 and 4 mpg, not really enough to warrant turning it off if it’s blazing hot outside.
One question that many drivers have is how long they can keep driving once the “low fuel” warning light starts blinking. The fact is that there’s really no set rule and it differs from car to car. The average car has between 1 and 2 gallons of gas left in the tank when the light starts blinking, about enough to travel 40 miles. If you’re far from a gas station when your fuel light starts blinking, the best that is to slow down and maintain a steady speed.
As for whether a new air filter can increase fuel economy, it’s been found in numerous tests that it won’t. In most tests it increases acceleration and performance, but not MPG.
Finally, many people wonder if running their car when the tank is nearly empty is bad for the engine. In fact, it’s really not. In most cars the fuel pump is pulling gas from the bottom of the tank already, even if it’s full. Fuel filters at the tank and closer to the engine also take out any junk or gunk that might affect it.
We hope these myths that we’ve just busted have opened your eyes to what you can do and not do to save extra money this summer on gas. As always, remember that one of the best ways to save gas is simply to not use your car at all. With warm winter approaching, walking or using your bicycle is definitely an option.
