Engine oil is a crucial part of a car engine. All cars that have an internal combustion engine make use of it and no matter how good the engine is, or how high quality the oil, eventually the oil is used up and it begins to degrade. It’s when this happens that the oil in the car needs to be changed.
When the oil needs to be changed can depend on the type of car, what oil is used, and how often it is driven. The owner’s manual of the car can give more information on specific details. However the old adage suggests that you should change the oil every 3 months or 3,000 miles.
Driving in extreme weather or towing a heavy trailer behind the car will affect how much oil the vehicle uses.
Not changing the oil for a long period of time can cause the oil to become like sludge, which will eventually clog the engine.
