How to Change Oil

Tools and Materials Required

• Correct engine oil type, viscosity, and quantity from the owner’s manual
• Correct oil filter for your vehicle
• Socket wrench or box-end wrench for the drain plug
• Oil filter wrench if the filter cannot be removed by hand
• Oil drain pan large enough for the full oil capacity
• Funnel for adding new oil
• Gloves, safety glasses, and rags
• Replacement drain-plug washer or crush washer if required
• Ramps or jack stands if extra clearance is needed
• Sealable container for used oil transport

How to Choose the Right Oil

• Use the oil viscosity listed in the owner’s manual, such as 0W-20, 5W-30, or another manufacturer-specified grade.
• Use the oil specification required by the automaker, not only the viscosity. Some engines require specific synthetic, diesel, turbo, or manufacturer-approved oil standards.
• Check the oil capacity before pouring. Add slightly less than the full amount first, then recheck with the dipstick to avoid overfilling.
• Choose the correct filter by vehicle year, make, model, engine size, and filter type. Cartridge and spin-on filters are not interchangeable.
• If you are unsure about oil type, filter type, or capacity, ask a mechanic or parts professional before starting.

Step-by-Step Instructions

1. Step 1

   Confirm the oil, filter, and capacity

   Open the owner’s manual or a trusted vehicle-specific service reference. Write down the oil viscosity, required specification, oil capacity, filter part number, drain-plug washer requirement, and any torque specs.

2. Step 2

   Park safely and prepare the work area

   Park on level ground, set the parking brake, and let the engine cool until it is warm but not hot. Place cardboard under the engine area and set your drain pan, tools, rags, and new parts within reach.

3. Step 3

   Raise and secure the vehicle only if needed

   If you cannot reach the drain plug and filter safely, use ramps or jack stands on approved lift points. Do not rely on a jack alone, and gently rock the vehicle to confirm it is stable before working underneath.

4. Step 4

   Remove the oil fill cap

   Open the hood and remove the oil fill cap. This helps oil drain more smoothly and reminds you not to start the vehicle before refilling.

5. Step 5

   Position the drain pan and remove the drain plug

   Place the pan under the drain plug, allowing for the stream to travel outward at first. Loosen the plug with the correct wrench, then remove it carefully without putting your hand in the oil stream.

6. Step 6

   Let the old oil drain completely

   Wait until the flow slows to an occasional drip. Inspect the drain plug and washer for damage. Replace the washer if the manual requires it or if it looks crushed, cracked, or worn.

7. Step 7

   Remove the old oil filter

   Move the drain pan under the filter because more oil may spill. Remove the filter slowly. Confirm the old rubber gasket came off with the filter so you do not accidentally double-gasket the new filter.

8. Step 8

   Install the new oil filter

   Lightly coat the new filter gasket with fresh oil. Install the filter according to the filter instructions or owner’s manual. Tighten it snugly, but do not overtighten.

9. Step 9

   Reinstall the drain plug

   Wipe the drain area clean, reinstall the plug by hand first to avoid cross-threading, then tighten it to the correct spec if you have a torque wrench. Do not overtighten the plug.

10. Step 10

    Add new oil gradually

    Place a funnel in the oil fill opening and pour in most of the specified capacity. Wait a minute, check the dipstick if your vehicle has one, then add small amounts until the level is near full.

11. Step 11

    Run the engine and check for leaks

    Install the oil cap, start the engine, and let it idle briefly. Do not rev the engine. Turn it off and inspect around the drain plug and filter for leaks from a safe position.

12. Step 12

    Recheck the oil level

    Wait a few minutes for oil to settle, then check the dipstick on level ground. Add small amounts only if needed. The final level should be within the safe range, not above full.

13. Step 13

    Reset reminders and record the service

    Reset the oil-life monitor only if your manual explains how, then record the date, mileage, oil type, oil quantity, and filter used.

How to Dispose of Used Engine Oil Responsibly

• Pour used oil into a clean, sealable container. The empty new-oil bottle usually works well if it has a tight cap.
• Put the used filter in a leakproof bag or container and let it drain into the oil pan first if possible.
• Do not pour used oil into soil, drains, toilets, storm sewers, trash, or regular recycling bins.
• Take used oil and filters to a local auto-parts store, recycling center, service station, or municipal household hazardous waste facility that accepts them.
• Call ahead before visiting because quantity limits, fees, and filter rules vary by location.
• Do not mix used oil with coolant, brake fluid, gasoline, solvents, or water because mixed fluids may be rejected by recyclers.

Practical Example

Example: Your owner’s manual says your car needs 5W-30 full synthetic oil, 4.5 quarts, a specific spin-on filter, and a new drain-plug washer. You park on level ground, use ramps, drain the warm oil, replace the filter and washer, add 4 quarts first, run the engine briefly, then top up carefully until the dipstick reads full.

Common Mistakes

• Using oil viscosity or specification that does not match the owner’s manual
• Crawling under a car supported only by a jack
• Draining hot oil and getting burned
• Forgetting to replace or inspect the drain-plug washer
• Leaving the old oil-filter gasket stuck to the engine
• Overtightening the drain plug or oil filter
• Overfilling the engine with too much oil
• Starting the engine before adding new oil
• Pouring used oil into a drain, soil, or regular trash

Troubleshooting

When to Visit a Mechanic

• You cannot safely lift or access the vehicle.
• You are unsure which oil, filter, drain plug, or torque specification applies to your car.
• The drain plug or filter is stuck, stripped, cross-threaded, or damaged.
• You see metal shavings, coolant-like milky oil, fuel smell, or sludge during the oil change.
• The oil pressure warning light stays on after refilling.
• The vehicle leaks oil after the change or the oil level drops quickly.
• Your vehicle has a covered underbody, cartridge filter, reset procedure, or warranty requirement you are not comfortable handling.
