Getting Ready to Change Your Oil
Before you begin, gather all the necessary tools and supplies to ensure a smooth and efficient oil change process. Here’s what you’ll need:
- Wrench or Ratchet
- Socket Set
- Oil Filter Wrench
- Funnel
- Oil Drain Pan or Container
- Car Jack and Jack Stands OR Ramps
- Rags or Shop Towels for cleaning up spills
- Gloves (nitrile gloves are recommended)
- Safety Glasses
And of course, you’ll need the correct type and amount of new engine oil and a new oil filter specifically designed for your car.
Choosing the Right Engine Oil for Your Vehicle
Selecting the correct engine oil is crucial for your car’s performance and longevity. The recommended oil type for your vehicle is typically found in two places: printed on the engine oil filler cap itself and detailed in your car’s owner’s manual. If you’re unsure, consulting these resources is always the best first step. Many auto parts stores also have online tools or knowledgeable staff who can assist you in identifying the correct oil type for your specific make and model. A quick online search on websites like AutoZone by entering your vehicle’s year, make, and model can quickly provide the recommended oil and filter types.
Determining When to Perform an Oil Change
Regular oil changes are vital for maintaining your engine’s health and ensuring your car runs efficiently. The frequency of oil changes depends on several factors, including the age of your vehicle, the type of oil used, and your driving habits. Generally, older vehicles might require oil changes every 3,000 miles, especially if using conventional oil. Newer vehicles, particularly those using synthetic or synthetic blend oils, can often go between 5,000 to 7,500 miles, or even longer, between oil changes. Always refer to your owner’s manual for the manufacturer’s recommended oil change intervals for your specific vehicle.
Important Safety Precautions
Safety should always be your top priority when working on your car. Keep these safety guidelines in mind before you start:
- Never work on a hot engine. Allow your car’s engine to cool down completely before starting the oil change to avoid burns.
- Protect yourself. Wear gloves to keep your hands clean and protected from used oil, and safety glasses to prevent any debris or oil from getting into your eyes.
- Secure the vehicle safely. If lifting your car, always use jack stands to support the vehicle after using a jack. Never rely solely on a jack to hold the car’s weight while you are working underneath it. Ramps are a stable alternative for raising the front of your vehicle.
With safety covered and your tools ready, let’s proceed with these 5 straightforward steps to change your car oil.
Step 1: Safely Elevate Your Vehicle
To access the oil drain plug located underneath your car, you’ll first need to safely lift the vehicle.
You have two primary options for lifting your car: using a car jack and jack stands or using ramps.
If you opt for ramps, have someone spot you as you slowly drive your car onto the ramps to ensure you align correctly and don’t overshoot them. Once your vehicle is securely positioned on the ramps, for extra precaution, place wheel chocks or wooden blocks behind the rear wheels to prevent any rolling.
If you’re using a car jack, carefully position the jack at the designated jacking points on your vehicle’s frame (refer to your owner’s manual for these locations). Raise the car to a suitable height and then immediately place jack stands securely under the vehicle’s frame rails or designated support points. Remember, never get under a car supported only by a jack. Jack stands are essential for safety.

Step 2: Locate the Oil Pan and Drain the Old Engine Oil
Once your car is safely elevated, slide underneath and locate the engine oil pan.
The oil pan is typically a large, metal reservoir situated at the bottom of the engine. To gain clear access to the oil pan and drain plug, you may need to remove a plastic undertray or splash shield. These are usually attached with bolts, screws, or plastic fasteners and can be removed using basic hand tools. Newer vehicles often have these undertrays for aerodynamic improvements, but they are designed for easy removal for maintenance.
After removing the undertray, you’ll clearly see the oil drain plug at the lowest point of the oil pan.
Position your oil drain pan directly beneath the drain plug. Using the correct size wrench, loosen and carefully remove the drain plug by turning it counterclockwise. Keep a firm grip on the drain plug as you remove it, as warm oil will begin to flow out immediately. Let the old oil drain completely into the pan. Allow several minutes for the oil to drain thoroughly until it slows to a drip. Once drained, clean the drain plug and install a new drain plug washer (if applicable or recommended for your vehicle), then carefully tighten the drain plug back into the oil pan, tightening it to the manufacturer’s recommended torque specification if known, or snug it firmly by hand and then give it about a quarter turn more with the wrench. Avoid overtightening, which can damage the oil pan. Reinstall the undertray if you removed one.
Step 3: Remove and Replace the Old Oil Filter
After draining the old oil from the pan, it’s time to locate and replace the engine oil filter.
Move to the engine compartment under the hood and locate the oil filter. Its location varies depending on the vehicle make and model, but it’s typically attached directly to the engine block. If you’re unsure of its location, consult your owner’s manual. Some oil filters can be unscrewed by hand. However, if the filter is tight, use an oil filter wrench to loosen and remove it.
Position your oil drain pan beneath the oil filter location to catch any remaining oil in the filter and prevent spills. Once the old filter is removed, take your new oil filter. Before installing the new filter, lubricate the rubber gasket on the new filter with a bit of fresh, clean engine oil. This helps ensure a good seal against the engine block. Screw the new oil filter into place by hand until the rubber gasket makes contact, then tighten it an additional half to three-quarters of a turn as per the filter manufacturer’s instructions (usually printed on the filter box). Again, avoid overtightening.

Crucially, double-check that the old oil filter’s rubber gasket has not remained stuck to the engine block’s filter mounting surface. Installing a new filter on top of an old gasket will cause a serious oil leak.
Step 4: Lower Your Car and Add New Engine Oil
Now that the old oil is drained and the filter is replaced, it’s time to lower your vehicle and refill the engine with fresh oil.
Carefully lower your vehicle back to the ground if you used a jack and jack stands or drive it off the ramps if you used ramps. Ensure the car is on a level surface. Locate the engine oil filler cap under the hood. This cap is usually marked with an oil can symbol and often the recommended oil type. Remove the oil filler cap. Insert a funnel into the oil filler neck to prevent spills. Pour in the correct amount of new engine oil as specified in your owner’s manual.
Determining the Correct Amount of Oil for Your Car
The amount of oil your engine requires depends on its size and design. This crucial information is detailed in your owner’s manual and often also available online through vehicle specification websites or auto parts retailers. Start by adding slightly less than the specified amount, as it’s easier to add more oil than to remove excess.
Step 5: Check the Engine Oil Level
After adding the new oil, wait a few minutes to allow the oil to settle in the engine. Then, locate the engine oil dipstick, usually a brightly colored handle near the engine. Pull out the dipstick, wipe it clean with a rag, and reinsert it fully. Pull it out again and check the oil level. The oil level should be between the minimum and maximum marks on the dipstick. If the oil level is below the minimum mark, add a little more oil and recheck. Avoid overfilling, as this can also be detrimental to your engine.
Once the oil level is correct, replace the dipstick and securely tighten the oil filler cap. Start your engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter. Turn off the engine and check the oil level again with the dipstick after a few minutes of settling. Finally, remember to properly dispose of the used oil and old oil filter at a designated recycling center or auto parts store.
Congratulations! You have successfully changed your car’s oil.
Frequently Asked Questions About Changing Car Oil
Can I just add more oil instead of changing it entirely?
Simply adding oil, also known as “topping off,” is not a substitute for regular oil changes. Over time, engine oil degrades, losing its viscosity and effectiveness in lubricating engine parts. This breakdown occurs due to heat, friction, and combustion byproducts. Old oil becomes contaminated with dirt, metal particles, and sludge, which can harm your engine. Mixing old and new oil dilutes the detergents and additives in the new oil, reducing its protective qualities. Regular oil changes replace the old, degraded oil with fresh, clean oil, ensuring optimal engine lubrication and longevity.
