Have good common knowledge about cars? Take the true-false car myth quiz:
Automatic transmissions are less fuel-efficient.
False. Today, automatics feature lock-up torque converters, six+ speeds and cruise control, and are just as fuel-efficient as manuals.
Premium fuel is better than regular for your non-premium vehicle.
False. Premium indicates gas is higher-octane, not higher in quality. Check your owner’s manual and see what fuel is required. Most run fine on regular.
Engines don’t need to warm up if it’s cold.
True. With today’s electronic fuel injection, there’s no need to warm up the engine.
