DIY oil-change steps
If you’re changing the oil yourself, follow these general steps to ensure a proper fill and level.
- Warm the engine to operating temperature to help drain the oil.
- Safely lift and support the vehicle if needed; place a drain pan underneath the oil pan.
- Place a new drain plug washer if equipped and remove the drain plug to drain the old oil completely.
- Remove and replace the oil filter with a new one, lubricating the gasket with a little new oil.
- Reinstall the drain plug and tighten to the manufacturer’s specification.
- Pour in approximately 5 quarts to start, using a funnel; don’t fill all at once.
- Replace the oil fill cap, run the engine for about a minute, then turn off and wait a few minutes for the oil to settle.
- Check the oil level with the dipstick and top up in small increments until it reads within the full range.
- Check for leaks around the filter and drain plug; reset the oil life monitor if applicable.
Dispose of used oil properly and recycle the oil filter at an authorized facility.
