FAQs
Does buying premium gas make my car more efficient?
Unless your vehicle’s manufacturer explicitly requires premium fuel, paying for a higher octane rating will not improve your gas mileage or engine performance. Standard engines cannot utilize the higher combustion resistance of premium fuel, meaning you are simply paying a higher unit price for zero mechanical benefit. Always check your owner’s manual and use the lowest octane rating recommended for your specific engine.
Is it better to leave my car running if I am only stopping for a minute?
No, it is not better to leave your car running. Modern fuel-injected engines start highly efficiently and use less fuel to restart than they do idling for just ten seconds. If you are waiting at a long drive-through line or a lengthy train crossing, turning the engine off will actively reduce your gas costs and lower your tailpipe emissions.
Do aftermarket fuel injector cleaners actually save gas?
For most modern vehicles running on Top Tier detergent gasoline, aftermarket fuel injector cleaners are an unnecessary expense. Major gasoline brands already blend federal-mandated cleaning detergents into their fuel to prevent deposit buildup. Unless you are driving an older, high-mileage vehicle experiencing rough idling or severe performance drops, pouring a $12 bottle of cleaner into your tank rarely offers a positive return on investment.
When should I roll down the windows instead of using the air conditioning?
The crossover point for efficiency is generally around 45 to 50 miles per hour. At lower city speeds, aerodynamic drag is minimal, making open windows more efficient than running the air conditioning compressor. At highway speeds, the massive aerodynamic drag created by open windows burns far more fuel than simply rolling them up and running the air conditioner on a low setting.
Where can I find the correct tire pressure for my vehicle?
The correct tire pressure for your vehicle is printed on a placard located on the inside edge of the driver’s side door jamb, or inside your owner’s manual. Never inflate your tires to the maximum PSI molded into the rubber sidewall of the tire itself, as that number indicates the physical limit the tire can hold, not the optimal pressure for your vehicle’s weight and suspension.
