Here's a general guide, but remember to prioritize your owner's manual's instructions:
Tools and Materials You'll Need:
* New oil: The correct type and quantity specified in your owner's manual (usually 5W-20, 5W-30, or another grade).
* New oil filter: The correct filter for your engine (check your manual or auto parts store).
* Oil filter wrench: The type depends on your filter; some are cap-type, others require a strap wrench.
* Wrench for the drain plug: Usually a 13mm or 14mm socket, but check your manual.
* Drain pan: To catch the old oil.
* Funnel: To pour in the new oil.
* Jack and jack stands (or ramps): To safely lift the car. Never work under a car supported only by a jack.
* Gloves: To protect your hands.
* Rags or paper towels: For cleanup.
* Torque wrench (recommended): To tighten the drain plug to the manufacturer's specified torque.
Procedure:
1. Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily. Don't let it get too hot.
2. Secure the vehicle: Use a jack and jack stands to safely lift the front of the car. Refer to your owner's manual for jack points. Alternatively, use ramps. Engage the parking brake.
3. Locate the drain plug: This is usually located on the bottom of the oil pan.
4. Position the drain pan: Place the drain pan under the drain plug.
5. Remove the drain plug: Carefully loosen and remove the drain plug with your wrench. Be prepared for hot oil to flow out.
6. Drain the oil: Let the oil drain completely. This can take 15-20 minutes.
7. Replace the drain plug: Once the oil has drained, carefully reinstall the drain plug and tighten it securely (but not too tight; use a torque wrench if you have one).
8. Locate the oil filter: The location varies by engine but is usually accessible from the bottom or top of the engine.
9. Remove the old oil filter: Use the oil filter wrench to remove the old filter. Some oil will likely spill, so have rags ready.
10. Prepare the new oil filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil.
11. Install the new oil filter: Screw the new oil filter on by hand until it's snug. Then tighten it according to the manufacturer's instructions (usually about ¾ to 1 full turn after the gasket contacts the engine).
12. Lower the vehicle: Carefully lower the vehicle using the jack.
13. Add new oil: Using a funnel, pour the correct amount of new oil into the engine (as specified in your owner's manual).
14. Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
15. Run the engine: Run the engine for a few minutes.
16. Check for leaks: Inspect the area around the drain plug and oil filter for any leaks.
17. Check the oil level again: After running the engine, let it sit for a few minutes and then re-check the oil level. Add more if needed.
18. Dispose of the used oil properly: Take the used oil to a recycling center or auto parts store that accepts used oil.
Important Notes:
* Safety first: Always prioritize safety. Use jack stands, wear gloves, and work in a well-ventilated area.
* Consult your owner's manual: This guide is general; your owner's manual contains specific instructions for your Dodge Avenger's model and year.
* Dispose of used oil responsibly: Used motor oil is hazardous waste and must be disposed of properly.
