Fiction?
Straight Answers by The Car Coach
Fact-or-Fiction? Premium gasoline is best for your vehicle.
Answer: Hoax, if your vehicle is designed to be run on regular gasoline, then filling your tank with premium will do nothing for you but send you to the poor house. However, if the manufacturer suggests premium fuel for your car...well, you can probably figure it out from there.
Fact-or-Fiction? Do not park with two wheels on the curb, as it will destroy the vehicle's alignment.
Answer: True, if done continuously. Service specialists say that repeatedly parking a car with one side's wheels up on a curb to provide more space for passing cars can cause excessive wear or stress to tie rods and suspension bushings and could create alignment issues, and you don't want those; trust us.
Fact-or-Fiction? If the steering wheel shakes when you drive, there is something wrong with your brakes.
Answer: Maybe myth, maybe hoax, maybe true. While they won't nail this down completely, you can bet if the wheel shakes as you depress the brake pedal, it may mean your brake rotors are unbalanced. If the wheel shakes as you drive, it may be the result of a wheel balance or steering-related issue.
Fact-or-Fiction? You should always warm your car up before driving on a cold day.
Answer: Myth. Although the majority of the driving population may consider this to be true, it can actually cause damage to vehicles if done continuously. (Instead of letting your car warm up in your driveway, drive it slowly and easily the first few miles until it comes up to operating temperature.)
