What car maintenance myth do you still hear people believe?

There are plenty of car maintenance myths that just won't go away.

• Premium fuel makes every car perform better.
• Warm up your car for 10 minutes before driving.
• Brake squealing always means the pads need replacing.
• A check engine light will go away if you ignore it.
