Engine Oil is Important
Your vehicle’s engine contains moving and sliding parts which operate under extreme heat with a lot of force. These metal parts must be kept lubricated to prevent damage, reduce friction, and maximize the life of your engine. Engine oil circulates constantly through your engine, providing the necessary lubrication.
Why Does the Oil Need To Be Changed?
Over time, your engine oil loses its effectiveness and must be changed.
The extreme heat in your engine makes the oil oxidate and break down. This changes the oil’s chemistry and makes it much less effective.
Oil also thickens over time. Thick, sludgy oil clogs narrow oil passages and prevents oil from reaching vital components, causing them to rub against each other with insufficient lubrication, which is harmful to your engine.
Your oil filter and air filter do their best to keep things clean, but over time contaminants always find their way into your engine oil. Your oil filter removes contaminants as the oil circulates, but eventually the air filter, oil filter and engine oil all get clogged with dirt and need to be changed.
