FAQs
Does using premium gas improve my fuel mileage?
Unless your vehicle’s manufacturer explicitly requires premium fuel, using higher-octane gasoline will not improve your mileage or clean your engine faster. Standard passenger vehicles are tuned to run efficiently on regular 87-octane fuel. Paying an extra fifty to eighty cents per gallon for premium is a complete waste of money for these engines.
Is it cheaper to leave the car running or turn it off while waiting?
Modern fuel-injected engines consume very little fuel during the startup sequence. If you are going to be stopped and waiting for more than sixty seconds—such as sitting at a long train crossing or waiting outside a store—it is absolutely more efficient to turn the engine off. Idling gets zero miles per gallon and needlessly wastes fuel.
How much does a roof cargo box actually affect highway fuel economy?
A large, aerodynamic roof box can reduce highway fuel efficiency by 10 to 25 percent depending on your speed and the vehicle’s shape. The faster you drive, the more aggressively that wind resistance hurts your wallet. You should always remove roof boxes, ski racks, and cargo baskets the moment you return from your trip.
Do pour-in fuel injector cleaners actually save money?
Most high-quality, top-tier gasoline brands already contain the federally mandated detergents required to keep fuel injectors clean. Buying a $12 bottle of fuel additive at the auto parts store rarely provides a measurable increase in fuel efficiency for a well-maintained vehicle. You are better off putting that money toward regular oil changes and clean air filters.
What is the best time of day to buy gas to get the most for my money?
An old myth suggests buying gas early in the morning when the ground is cool gives you denser, more energy-packed fuel. Because gas station storage tanks are buried deep underground, the temperature of the fuel remains highly consistent regardless of the time of day. You should buy gas whenever it is convenient and fits into your consolidated route planning.
