Is it possible to improve a vehicle's fuel efficiency?
There are things you can do to slightly improve the fuel efficiency of your vehicle. Make sure your car's tires are properly inflated, and treat your engine to regular tune-ups. Check your engine's air filter, since a dirty air filter will compromise fuel economy.
Why must drivers shut off their engine before pumping gas?
Drivers must shut their engine off before pumping gas because it's illegal to fuel with the engine running, even though this law isn't always aggressively enforced. Pumping gas with the engine running can compromise your safety. When your car's engine is running, it's possible for its catalytic converters to generate heat that could ignite gasoline, and start a fire.
Can cell phones ignite a gasoline vapor fire?
Even though many gas stations have warnings advising you not to use your cell phone while fueling, the chances of cell phones igniting a gasoline vapor fire are extremely remote. However, fires at the gas pump may be caused by static electricity discharge. For safe fueling, it's recommended that you turn off your car's engine and avoid smoking at the pump. Also, you should never re-enter your vehicle while refueling.
Why are gas prices not uniform, even across same-brand stations?
Many factors contribute to the lack of uniformity in gas prices. Retailers consider their tax responsibilities when setting gas prices. States place varying taxes on gasoline retailers, and a state with higher taxes will have higher gas prices than a state in which the taxes are lower. Also, if a gas station is located in an especially competitive area, a branded operator may receive wholesale discounts that allow the station to sell gas at a lower price. This is done by brands to keep their gas competitive in tight markets.
