​Your Chevy's Oil Filtration System

Your GM engine care begins with regular oil and filter changes, which must be a part of your vehicle's regular maintenance regimen. If you avoid changing the oil and its filter, you are shortening the life of your vehicle and create expensive repairs, including the need to replace the engine. Maintenance is especially important during the harsh winter weather and humid summers that are experienced here in Creve Coeur, Missouri. You should never wait to change the filter based on signs that indicate a need. By that point, dirty oil has already gained access to the engine and the damage can quickly escalate. 

Chevy Oil Filters

Your Chevy's oil filter protects the engine from solid contaminants, such as soil, carbon and metal particles. These pollutants wreak havoc within the engine and can damage the bearings and cylinder wall surfaces. Selecting an authentic Chevy OEM filter is the best choice because it is designed by Chevy to catch more dirt and contaminants. Chevy produces the best quality, perfectly fitting filters. 

Engine Filtration System

The Chevy's full-flow filtration oil system brings oil in through the pump and routes it through the filter before bringing it to the crankshaft bearings, cam bearings and finally to the valvetrain. An accumulation of solid debris becomes trapped in the filter over time, and this trapped debris will begin to restrict the steady flow of oil into the engine. Your Chevy OEM filter must regularly be changed before it is clogged or filthy. When it is clogged a bypass valve within the filter opens and permits an influx of oil into the engine. This is a safety that ensures that oil gains entry into the engine if the filter becomes dangerously clogged, but it allows dirty, unfiltered oil into the engine. 

What Happens When the Oil Filter isn't Changed?

Your engine can not perform correctly with dirty oil. Contaminants will damage the motor.

• Dirty oil will thicken and become abrasive. This rough oil causes unwanted wear within the engine.

• The oil contains detergents, rust-fighters and friction reducers, which are lost when the oil isn't properly filtered.

• Unfiltered oil becomes thick and dirty and provides inadequate lubrication for the engine.

Be Aware of Signs that Your Oil Filter is Dirty

If you recognize signs that your oil filter is dirty, replace the filter with a high-quality, factory-designed oil filter. Chevy OEM oil filters are designed to block dirt, debris and solids from entering the engine. The filter works together with the oil to maintain constant lubrication to the engine and to keep the metal components in the engine performing at their best without issues. The following symptoms may be experienced when your engine is lubricated with contaminated oil due to a clogged or overly dirty filter. 

1. Decreased Performance

Pay attention to the performance of your Chevy, and check the filter and oil levels if your Chevy experiences a reduction in its normal level of performance. If the engine feels or sounds different when you accelerate, this may indicate a reduction in its ability to perform. If you continue to operate the vehicle at this level of performance, you may damage the engine and create the need for additional repairs. Your vehicle communicates with you. Listen to and feel its power, and quickly respond when you sense a reduction in its ability to perform. When your traveling to the Dielmann Recreation Complex for a beautiful day at the golf course, listen to your engine. If you notice a reduction in performance, check your oil and the filter.

2. Is Your Chevy Sputtering or Hesitating?

If your car is sputtering or hesitating, the filter may be clogged. A clogged filter often compromises the steady release of clean oil to the engine, which hinders the engine from reaching or maintaining its speed. Light sputtering and hesitations should be quickly addressed. Simply changing the oil and the filter should resolve the issue. If this issue continues after you have replaced the filter, look for other causes, such as dirty fuel injectors, bad MAP or TPS sensors, vacuum leaks or dirty fuel. 

3. Metallic Noise in the Engine

When the filter is excessively dirty or clogged, the engine may lack oil. A lack of oil may allow the metal parts to grind or touch when the engine is running. When you hear metallic noises coming from the engine, pull over immediately, add oil and check for a clogged filter. Complete an oil and filter change as soon as possible, and test the engine for signs of damage or performance issues. 

4. A Drop in Oil Pressure

Watch your gauges when you are driving, and if you see a drop in the oil pressure, check the oil and the filter. A rapid drop in pressure will require pulling over and accessing the issue immediately. Regular changes in oil pressure are only a fraction of a percent. 

5. Black Exhaust

When the oil filter becomes clogged, the exhaust may become black and dirty and may smell like burning oil as it leaves the exhaust pipe. This odor indicates a problem that required immediate attention. Replace your oil filter, remove sludge that has entered the engine and look for any clogs or leaks.

Change your oil and the filter regularly. Use high-quality Chevy filters that will protect your engine from dirt and sludge, because low-quality filters perform poorly. 

Recommended Oil and Filter Maintenance

Remove the accumulation of moisture, acids and sludge from your oil by changing the oil and filter regularly. The filter will remove the solid contaminants, and you must replace the oil to remove moisture, acids or sludge. Do not select replacement filters based on appearance. Instead, choose perfectly-sized and factory-measured OEM filters. Your Chevy requires the correct filter. Oil filters are designed to fit specific engine models that may require filters with SAE or metric threads or sideways mounted filters that need the anti-drain back valve to prevent oil from draining when the engine is shut off. 

Your oil maintenance and filter changes should be based on the use of the vehicle. Most Chevy's have a factory-installed Oil Life System (OLS), which is a gauge that calculates your engine's speed, its temperature and operating conditions to determine when you should change the oil and the filter. A 3,000-mile or six-month rule was recommended years ago, but this has changed. The newer recommendations are to change the oil every 7,500 miles or once a year. However, if your vehicle has more than 70,000 miles, you should replace the oil and filter more often. Sports cars, such as the Chevy Camaro, should also have the oil changed more frequently because of the high temperature that the engine reaches during its peak performance.
