Nobody likes to pay for car repairs, but routine oil changes are one of the most inexpensive preventative maintenance steps you can take to make sure your vehicle lasts for the long haul. It might also help prevent more expensive repairs down the road.
What does oil do?
The oil in your car's engine has three main roles.
How often should I change my oil?
This is certainly one of the most common vehicle maintenance questions. Unfortunately, there is not a single answer. The right answer depends on the make and model of your car and what kind of conditions you usually drive in. Check your owner's manual for the recommended schedule.
What would happen if I didn't change my oil?
The short is answer is very bad things. Carbon deposits and other buildup will begin to take over your engine, especially in places like the crankcase and around the camshafts and valves. You can also get sludge in your engine. With all of these issues, you might need an expensive engine cleaning.
And, it can get even worse. The pistons in your engine could eventually seize and the camshafts could get damaged. If this happens, a bill for an oil change will seem like small pocket change.
So, get your oil changed like you should, and keep your car running great.
