How Often Should You Change You Motor Oil?

It seems that different people have different opinions on how often you should change the motor oil in your car. We’re here to give you some tips to help you understand both why you need to change your motor oil and how often.

What influences how often you need to change your motor oil.

  • Hard driving. Driving long distances, extreme weather, towing a trailer, long idle times or stop-and-go traffic situations, they all take a toll on your car. Ultimately this means you need to change your oil more often.
  • Older cars. Older cars need to have their motor oil changed more often because of what’s known as “blowby”, which is compressed air and fuel that seeped into the crankcase. In addition, grime builds up on the rings and they become porous, which contaminates the oil. .
  • Car storage or infrequent driving. If you’re not driving your vehicle very much you probably won’t need to replace your motor oil as often. This is when you can probably follow the recommendations in your owner’s manual.

Check your owner’s manual. Most manuals will say that you should change your motor oil between 5,000-7,500 miles during ideal driving conditions. This includes perfect temperatures, short trips, no-speeding, and so on. Is this how you drive? Many people don’t, so the next best assumption is to change your motor oil every 3,000 miles or so.
