6 CAR MYTHS WHICH WASTE YOUR MONEY

SmartCarPlain

MYTH: CHANGE YOUR OIL EVERY 3000 MILES OR 5000 KILOMETERS

The truth is that synthetic oils can last from 7500 miles to 20,000 miles or 12,000 to 32,000 kilometers depending on the type that your car manufacturer recommends.  Check where you change the oil and find out how long it is designed to last and make adjustments. If you wind up changing your oil every 15,000 miles you may wind up saving as much as 80% on your oil changes.

MYTH: WARM UP YOUR ENGINE BEFORE YOU DRIVE ON COLD DAYS

There is much more cold wear and tear if you idle the car on a very cold day because it takes the oil longer to heat up on a cold day.  If you start to drive it right away then the oil will heat up much faster and there will be less TOTAL wear and tear on the moving engine parts.

MYTH: ADD EXTRA FUEL ADDITIVES FOR YOUR ENGINE

Since 1995 manufacturers have been required to add fuel additives to gasoline which are designed to clean your engine of unwanted engine deposits so adding more is just wasting your money and your engine will not run any cleaner.

MYTH: GET REGULAR ENGINE TUNEUPS

With fuel injection cars and computer chips making fine tuning adjustments to your car all that you really need is to change your spark plugs and air filter about every 50,000 miles or 80,000 kilometers.

MYTH: WINTERIZE YOUR CAR

If you are using 5W-30 oil then it is good for summer or winter and year round radiator fluid is rated to go as low as -34 degrees Fahrenheit or -36 degrees celcius so you really don’t need to winterize your year round car.

MYTH: HIGH OCTANE GASOLINE IS BETTER FOR YOUR ENGINE

It is a myth that higher octane means that your car will have more power, better mileage, and run smoother. Only a very small percentage of high performance cars will knock or detonate with lower octane gas because they have high compression ratios which normal cars do not. The rest of the cars do very well on regular or 87 octane which is closer to 90 octane with ethanol added. A high octane sounds sexy because it is a bigger number but the truth is that you are just wasting your money with no increase in car performance, smoothness, or mileage economy.
