Technology has made us smarter. We can navigate the information highway in record speed and in multiple windows. We can program our TiVo so we can tweet about our ideas while simultaneously connecting with friends on Facebook. But when is comes to our car’s technology most of us are dumbfounded. Overwhelmed by our lack of admitted knowledge, we may pay a price $$ for things that aren’t needed or really necessary. Worse, we may perpetuate bad advice and pass it down to our kids, spouse or friends.

I am not a car wizard, but in an attempt to weed out the facts from the fiction (or more likely old outdated information) I did the research for you. Here are 4 common pieces of misinformation about cars.

True or False: You can trust your father’s advice, your car needs an oil change every 3 months or 3000 miles whichever comes first?

If you’re like many people you answered True. But the real answer is False. Consumer Reports found that under normal driving conditions in many cars you can actually change the engine oil and filter every 7,500 miles or six months, whichever comes first. The outdated thinking doesn’t take into account improvements in the engines and synthetic oils. AutoNation believes your best bet is to read your car’s owner’s manual for the recommended oil change interval. It will usually advise longer than three months/3,000 miles.

True or False: Manufactures of car products want you to buy their product to wash your car, but the truth is you can wash the car with the same soap you use to wash your dishes.

It would seem to make sense that if you can clean your dishes with it, you can clean your car, but the real answer is False. According to Motor Trend, household soaps and detergents are just too strong to care for your cars professional paint finish. Sure dish soap will remove dirt and grease easily, but is will also strip the protective wax coating off a car, leaving the paint more vulnerable to environmental damage.

True or False: Your car is a safe place to be in a lightening storm, just don’t talk on your cell phone while you’re waiting for the storm to pass.

Unless your car is the tallest object in the area, the answer is True. The car’s metal bodywork should act as a Faraday cage, safely conducting the lightning to the ground around you—that is if you’re not touching anything inside the car advises Popular Mechanic. And, yes you can talk on your cell phone while waiting for the storm to pass as long as it’s not connected to anything conductive, like a car charger.

True or False: One way to improve your car’s performance is to use high octane gasoline.

You might be surprised to learn that the correct answer is False. Most cars only need regular octane gasoline. There appears to be no benefit to using a higher octane gasoline than your owner’s manual recommends. High octane gasoline won’t make your car perform better, go faster, get better mileage or run cleaner, according to the Federal Trade Commission. The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. AutoNation advises you follow your owner’s manual recommendations.

While many of us don’t read our car’s owners manual doing so can save you time and money. You don’t need to read the manual cover to cover. Instead, look up key facts. What should your tire pressure be? How often does your car need oil changes and other maintenance services, etc. On a separate piece of paper jot down the information with anticipated miles/dates for service and keep the information with your owners manual. At the beginning of every month pull out the paper to see when and what type of service is needed and schedule the appointment. You car prowess will be the envy of all your non-mechanic friends.
