ST. LOUIS, MO (KPLR) - As you gear up for you summer road trip, make sure your car is ready too!

Randy Holman with Christian Brothers Automotive is busting some myths about cars!

  1. Turning on the air conditioner is better for fuel economy. The A/C leads to a 'slight decrease in fuel economy' according to Mythbusters and Consumer Reports, but keeping it on is a good way to keep the driver alert and comfortable.
  1. You need to change your oil every 3,000 miles or never change it at all. This was true of older cars but many modern cars can go as far as 10,000 miles without fresh oil. However, the older the oil gets the more likely it is to stop lubricating which causes wear and tear to your engine.
  1. Inflate tires to the pressure shown on the tire's sidewall. It's important to look at the automaker's recommended tire pressure rather than the figure listed on the tire. The PSI often lists the maximum pressure the tire will hold safely.
  1. Warm your car up for several minutes before hitting the road. Actually, driving the car is the fastest way to warm up the engine and delivers the best mileage and performance.
  1. Keeping the car engine on during short stops saves gas. Modern engines crank more efficiently than older models, and avoiding excessive idling can save up to 19% of the gas.
