Oil is needed to lubricate the many engine components that work together to make a vehicle run. Without oil the engine would quickly overheat and parts would wear out prematurely. But every time oil circulates through the engine it can become contaminated.
The oil filter keeps debris and dirt out of the oil while the engine is running. A properly-working oil filter is critical to your car’s smooth operation, engine life and fuel mileage. If you can change your oil, you should be able to replace the oil filter.
Plus, it’s best practice to replace the oil filter every time you change your oil. You may need to change the oil and filter every 3,000 miles but many newer vehicles require less-frequent changes up to 10,000 miles.
If you’ve seen an older car with its engine sputtering and puffing out black smoke, it could be due to a dirty air filter. Long before a newer car starts puffing smoke, the check engine light will come on because the air filter is past its prime.
An air filter is a very simple component in the air intake that’s able to keep the air going into the engine clean of contaminants. The screen keeps out bugs, water, road grime, pollen, dirt and everything else that blows into your vehicle’s grill.
The air filter is one of the simplest parts to change or clean. You can remove the intake hose attached to the air collection box and lift out the filter. Hold the filter up to the light. If you can’t see light through it, you should clean or replace it.
