Summer Driving & Fuel Economy Myths Dispelled

As the weather warms up, drivers begin thinking of the services needed to maintain their vehicles now that winter has passed. Unfortunately, it’s during this time of year, that automotive myths are often unintentionally perpetuated.  Knowing which stories are myths and which ones are fact can be difficult. Because of that, NAPA’s 2009 Technician of the Year, Jack Gregory, is dispelling some common myths to keep everyone’s vehicle running smoothly in 2009.  

Myth: Driving at 56 mph will give you the best fuel economy.
Fact: Although most vehicle manufacturers base their product’s gas mileage at 56 mph, driving at that speed doesn’t guarantee the best gas mileage. Keeping a consistent speed, whether it’s 25 mph or 65 mph, will ensure the best fuel economy.  

Myth: Filling your cooling system with all water and no anti-freeze will save you money while not harming your vehicle.
Fact: The vehicle’s cooling system requires a mixture of half water, half anti-freeze. “Too much anti-freeze causes the vehicle to run on higher than optimal temperatures,” cautions Gregory. "Too much water can cause lower operating temperatures and possible freezing."

Myth: Driving closely behind an 18-wheeler will protect you from headwinds and allow your car to use less gas.
Fact: This doesn’t help with gas mileage, is dangerous and can be illegal. A sudden stop from the 18-wheeler could force a driver to slam on the brakes or even worse, cause an accident.
