Time needed: 30 minutes
Here’s a step-by-step guide to help you change your car’s oil.
Tools and Materials You’ll Need:
– Oil filter wrench
– Oil drain pan
– New oil filter
– Fresh oil (refer to your owner’s manual for the correct type and amount)
– New oil drain plug (some people change this too, or like to have one around in case the old one wears out)
– Socket wrench set
– Funnel
– Gloves and rags
– Car jack and jack stands or ramps (if necessary)
– Oil filter removal tool (if necessary)
- Warm Up the Engine:
Before you start, warm up your engine for a few minutes. Warm oil drains more easily than cold oil. However, don’t let it get too hot, as you don’t want to risk burns.
- Lift the Car (If Necessary):
If your car has low ground clearance, you may need to lift it using a jack and secure it on jack stands. Always use jack stands for safety—never rely on the jack alone.
Another option is using ramps. They might be easier to use and still provide the required safety. - Locate the Oil Drain Plug:
Find the oil drain plug underneath your car. It’s usually located on the bottom of the oil pan. Place the oil drain pan directly under the plug.
- Drain the Old Oil:
Using a socket wrench, carefully loosen and remove the drain plug. Allow the old oil to drain completely into the oil pan. This may take several minutes. Once drained, replace the drain plug and tighten it securely.
- Replace the Oil Filter:
Locate the oil filter, which is typically on the side of the engine block. Use an oil filter wrench to loosen and remove the old filter. Be prepared for some oil to spill out when you remove it.
Make sure the old gasket comes off. Sometimes, it remains on the filter, sometimes on the car. Double-check because the new filter will come with a gasket, and you don’t want a double-gasket situation!
Before installing the new filter, apply a small amount of fresh oil to the rubber gasket on the top of the new filter. This ensures a proper seal and makes it easier to remove the filter next time. Screw the new filter on by hand until it’s snug, then give it an additional quarter turn. - Add New Oil:
Remove the oil filler cap on top of the engine. Using a funnel, pour in the new oil. Refer to your owner’s manual for the exact type and amount of oil your engine requires. After adding the oil, replace the filler cap.
- Check for Leaks:
Start the engine and let it run for a minute or two. Check underneath the car for any signs of leaking oil. If you see any leaks, turn off the engine and check that the drain plug and oil filter are properly tightened.
- Check the Oil Level:
After the engine has run for a few minutes, turn it off and wait a few minutes for the oil to settle. Pull out the dipstick, wipe it clean, and then reinsert it fully. Pull it out again to check the oil level. It should be within the recommended range indicated on the dipstick. If necessary, add more oil until you reach the correct level.
- Dispose of the Old Oil:
Used motor oil is hazardous and must be disposed of properly. Most auto parts stores and service stations will accept used oil for recycling. Transfer the old oil from the drain pan to a sealed container and take it to a recycling facility.
- Reset the Oil Change Light (If Applicable):
If your car has an oil change reminder light, reset it according to the instructions in your owner’s manual.
Tips for Success:
- Stay organized: Keep all your tools and materials within reach before you start.
- Work safely: Always use jack stands if you need to lift your car, and never work under a car supported only by a jack.
- Keep it clean: Use rags to wipe up any spills and dispose of them properly.
By changing your oil regularly, you’ll help ensure your engine stays well-lubricated and performs optimally. This simple maintenance task can significantly extend the life of your car and save you money on costly repairs down the road.
