Changing the oil on a Chevy Silverado is no different that changing the oil on most Chevy models. Use a 6-point socket wrench for the oil drain plug. The original engine oil drain plug wrench size should be a metric size. Most use a 15mm and on some models, a 13mm. Use a typical banded oil filter wrench for the filter.
The recommended oil viscosity is 5W-30 or 10W-30. As shown in the chart, SAE 5W-30 is best for your chevy truck. However, you can use SAE 10W-30 if it’s going to be 0°F (-18°C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50.
When to Change Engine Oil
Your vehicle has a computer that lets you know when to change your engine oil. This is not based on mileage, but on engine revolutions and engine operating temperature. When the computer has calculated that the oil needs changing, the Oil Life Monitor will indicate that a change is necessary. The mileage between oil changes will vary depending on how you drive your vehicle -- usually between 3,000 miles (5 000 km) and 7,500 miles (12 500 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 7,500 miles (12 500 km) or 12 months (whichever occurs first) without an oil change. The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil every 3,000 miles (5 000 km) or sooner. Remember to reset the CHANGE ENGINE OIL message whenever the oil is changed.
- Crack open your favorite cold beverage.
- Lift your Silverado using at least a 2-ton jack and then place the truck on jack stands making sure the stands are located on a solid portion of the trucks frame. If you don't have jack stands, drive the truck onto a set of sturdy wheel ramps.
- Pop the hood and remove the dipstick and oil filler cap. In a Silverado, the dipstick is to the left of the engine and has a yellow handle. The oil filler cap is to the right diagonal from the dipstick.
- Gather an oil drip pan, socket wrench, oil filter wrench, cleaning cloths and a new oil filter. Slide yourself under your Silverado.
- Locate the oil filter and oil drain plug underneath the truck. The oil drain plug is near the bottom of the engine block, and on the Silverado, the filter is to the left of the drain plug.
- Remove the oil drain plug using the socket wrench. Pull the plug out quickly and let the oil drain for 10 to 15 minutes. Check the gasket and threads for damage. Replace if damaged.
- Take off the oil filter using a banded oil filter wrench. Dump the old oil into the oil drip pan and put on the new oil filter. Tighten the oil filter by hand, and then replace the oil drain plug using the wrench.
- Under the hood, add new oil. Turn on the engine and check the oil pressure gauge to make sure it rises. If it doesn't, turn the car off quickly and add more oil.
- Lower your Chevy Silverado and turn off the engine. Take an oil reading on the dipstick. If the oil level isn't at full, add a bit more oil.
- Crack open another cold beverage and celebrate a job well done.
