Why Engine Oil Matters in the Chevy Silverado
You purchased a Chevy Silverado so you would have a rugged truck that will work hard for you. That means you also purchased an engine that you want to have working hard for you. Engine oil helps make sure that happens.
Every time you run your engine, the moving parts experience friction. That friction leads to wear and tear that can break things down over time.
Engine oil serves as a lubricate to reduce this wear and tear. While it does its job, it also cleans some of the components. This means it can pick up grit and grime that can damage your engine.
Oil changes are important parts of keeping your engine operating at peak efficiency. By taking out the junky oil and putting in fresh, you can maintain your engine well.
Using the right oil that is tailored to your engine is critical. For the 2003 Chevrolet Silverado 1500, that is 5W30 synthetic oil. This has the right weight and lubrication for the engine.
How to Change the Oil in a 2003 Chevrolet Silverado 1500
When your Silverado is due for an oil change, you can either take it in for service or do the job yourself. With the right tools, it’s not too difficult to do on your own. Check out this video to see how.
- First, find the oil filler cap and remove it. This will create good flow when you drain the oil.
- Then, put the truck on ramps or a jack, but do so safely. Look at this video for safety tips about raising your truck. If you are small enough, you might be able to slide under the truck without lifting it.
- Put the drain pan under the drain plug. Loosen the drain plug, and the oil will start to flow. Allow the oil to drain into the drain pan.
- Remove the old oil filter using a filter wrench. Break the seal, then loosen the filter by hand. You will need to remove the rubber gasket along with the oil filter.
- Install the new oil filter, lubricating the rubber seal using some clean engine oil. Tighten it by hand, then snug it up using an oil filter wrench. Only snug it ¼ turn past finger tightness because over-tightening can hurt the oil flow.
- Check to make sure all of the oil is out of the engine. Put the drain plug back in place and snug it using a ratchet and socket.
- Fill the engine with oil. Use 4.5 quarts for a V6 and 6 quarts for a V8.
- Lower the truck safely. Then turn on the engine and let it run. If you did everything correctly, the oil light will go off in just a little bit of time after you start the engine.
How Often Should I Change the Oil in a 2003 Chevrolet Silverado 1500?
The standard rule of practice is to schedule an oil change every 3,000 miles or three months. However, in 1999 Chevrolet added new tech to its Silverado trucks that can help answer this question.
GM’s Oil Life Monitoring System, which is included in most 2003 Silverado trucks, measures engine revolutions, rather than mileage, and indicates when an oil change is due based on that data. This provides a more accurate estimate of when the oil is not functioning properly.
If your truck has an Oil Life System that’s operating properly, you can wait to do the oil change until it indicates it’s needed. If not, then aim to have it every 3,000 miles or three months.
