Engine Oil Facts

  • Contrary to popular belief, the “W”  in the oil you’re looking at purchasing doesn’t actually mean weight, it means winter. For example, a 10W-30 means the viscosity of the oil is 30 and the 10W is the rating for cold oil that should be used in the winter.
  • Don’t believe that if your oil is dark,it’s dirty and needs to be changed immediately! The opposite is actually what you should be considering. Most engine oils use detergent additives which means that oil looks like it is supposed to, dark. Listen to what your car manufacturer’s advice is on oil changes, not the color of the oil on the oil stick.
  • No matter what your car’s manual says, you should always change your car’s oil at 3,000 miles. FALSE! Every car is different, and every engine is different. Depending on the type of detergent oils used, you could change your oil from every 3,000 to 7,500 miles. Depends on the oil and the engine you are using. If you are unsure, give your car’s manufacturer a call to get the best advice.
