6 Myths Concerning Engine Oil
Some myths are persistent and the ones about automotive motor oil may be the worst. You have undoubtedly heard some of them. Myths are funny things, once they get established, they aren’t easy to extinguish – even when real data enters into the arena. In this article we will look at the top six myths concerning the motor oil in your car and voice our opinions on their veracity.
1) Change your oil every 3,000 miles. Today this is a myth for the vast majority of modern cars. It used to be a recommendation from a few decades ago, and a good one. Experts agree that the oil in today’s cars last far longer and should be changed at the designated intervals specified by the manufacturer. The average interval for 2010 cars is around some 7,800 miles. By all means, check your owner’s manual or check with your local dealer to see what interval they recommend.
2) Check the oil on the dipstick. If it’s dirty looking, change it. Experts say this is another myth. Sure it looks like the oil is dirty and that can’t be a good thing but oil that gets dark does not mean it is necessary harmful to your engine. This is because oil has additives in it that change color as they work and turn dark, it may have plenty of life left in it even if its dark.
3) Always change your oil before long trips. There is some truth to this but it’s not just the oil that needs attention. It’s definitely a good idea to look your entire car over before long drives. That’s where the myth comes from. If the oil change interval that you adhere to arrives during the trip, then it’s a not a bad idea to change it before you leave.
4) When you buy a new car, change your oil at 1000 miles. This is another one. Decades ago, oil samples from engines during the first 1,000 miles of driving show elevated “wear-in” metal levels so that means that the oil should be changed after 1000 miles. Well, lets consider the thoughts from one prominent manufacturer. A Honda spokesman says its cars come from the factory with a special oil formulation for the break-in period and they don’t recommend changing it at 1000 miles! The take-away? Follow the manufacturer’s recommendations on the first oil change interval for your new car.
5) Once you switch to synthetic oil, you always have to use it. This is just a myth. In fact, the line between synthetic oil and petroleum-based oil is blurring because the two types of oil are often blended together today. Switch back and forth as much as you’d like.
6) You should always change your oil filter too. Actually, this one is true. Oil filters perform a critical job in your engine’s oiling system and they are cheap. It’s just good practice to install a new filter whenever you change your oil.
