You can replace an oil filter yourself in 15 to 30 minutes with basic tools
An oil filter replacement is one of the simplest maintenance tasks you can do on your own. You need a filter wrench, a drain pan, and the correct replacement filter for your vehicle — that's it. The job involves draining a small amount of old oil, unscrewing the old filter, and threading on a new one by hand. Most people finish in under half an hour, and you save the labor cost you'd pay at a shop.
The hardest part is usually finding where the filter sits on your engine. On most vehicles it's on the side or top of the engine block, but some cars — particularly those with turbocharged engines or tight engine bays — hide it underneath or behind other components. Your owner's manual or a quick search for your vehicle's year, make, and model will show you exactly where to look.
Key Takeaways
- You need a filter wrench, a drain pan, and the correct replacement filter for your vehicle model — check your manual or the old filter for the part number.
- The filter sits on the engine block and unscrews by hand after you loosen it with a wrench; it's not bolted down.
- Drain a small amount of old oil into a pan before you remove the filter to avoid spilling it on your engine.
- Hand-tighten the new filter until the rubber gasket touches the engine, then turn it three-quarters of a turn more — do not use the wrench to tighten it.
- Dispose of the old filter at a recycling center, auto parts store, or service station; many accept them for free.
Find the filter and gather your tools
Locate the oil filter on your engine by checking your owner's manual or searching online for your vehicle's year, make, and model plus "oil filter location." On most sedans and trucks, it's a cylindrical canister about 3 to 4 inches tall mounted vertically on the side of the engine block. On some newer vehicles, it may be a cartridge-style filter housed in a plastic cap on top of the engine.
Gather a filter wrench (a metal band wrench or cup wrench that fits your filter's diameter), a drain pan, a rag or old towel, and the replacement filter. Buy the correct filter by taking your old filter to an auto parts store or by looking up your vehicle's specifications online — the part number is printed on the old filter itself. You may also want a pair of gloves to keep oil off your hands.
Warm the engine and position the drain pan
Start your engine and let it run for 30 seconds to a minute, then turn it off. Warm oil flows more easily than cold oil, so this step reduces the amount of oil that stays trapped in the old filter. Do not let the engine run long enough to get hot — just warm enough that you can feel heat coming from the engine block.
Position your drain pan directly under the filter. Oil will drip out when you remove the old filter, and the pan catches it so you don't spill it on your engine, driveway, or garage floor. If your filter is mounted at an angle, tilt the pan to match the angle.
Loosen and remove the old filter
Wrap the filter wrench around the old filter and turn it counterclockwise to loosen it. Once it's loose enough to turn by hand, remove the wrench and unscrew the filter the rest of the way by hand. Tilt it slightly as you unscrew it to let the remaining oil drain into the pan. The filter will still contain a small amount of old oil, so work slowly and keep the pan underneath.
Once the filter is completely off, wipe the filter mounting surface on the engine block with a clean rag. Remove any dirt, old gasket material, or oil residue. This ensures the new filter's rubber gasket makes a clean seal against the engine.
Install the new filter
Pour a thin layer of new oil around the rubber gasket of the new filter — just enough to coat it lightly. This helps the gasket seal properly and makes the next filter change easier. Hand-screw the new filter onto the mounting surface until the rubber gasket touches the engine block. You'll feel a slight resistance when it makes contact.
Once the gasket touches, turn the filter an additional three-quarters of a turn by hand. Do not use the wrench to tighten it — hand-tight is correct. Over-tightening makes the filter difficult to remove next time and can damage the gasket. If you use the wrench, you've tightened it too much.
Check your work and dispose of the old filter
Start the engine and let it run for a minute while you watch the area around the new filter. Look for any oil leaks around the gasket or the base of the filter. If you see drips, turn off the engine, wait a minute, and tighten the filter slightly by hand — usually a quarter turn is enough. Restart and check again.
Once you confirm there are no leaks, turn off the engine and let it sit for a few minutes. Then check your oil level using the dipstick or electronic gauge in your dashboard. Top it off if needed — you may have lost a small amount during the filter change.
Take the old filter to a recycling center, an auto parts store, or a service station. Many accept used filters for free because the metal can be recycled and the oil is recovered. Do not throw it in the trash or pour the remaining oil down a drain.
Frequently Asked Questions
Do I need to drain the oil before I change the filter?
No — a filter change is separate from an oil change. You only drain the oil if you're replacing the oil itself. When you change just the filter, you let a small amount of old oil drain from the filter into your pan, but you keep the oil in the engine. If your owner's manual calls for an oil change at the same time, then you drain the oil first, change the filter, and add new oil.
What if the old filter is stuck and won't loosen?
Tap the filter wrench gently with a hammer to improve grip, or try wrapping a rubber band around the filter to increase friction. If it's still stuck, let the engine cool completely and try again — sometimes heat makes the metal expand and lock the filter in place. As a last resort, carefully puncture the filter with a screwdriver and use the hole to turn it, though this is messy.
Can I reuse the old filter?
No — oil filters are designed to be replaced, not cleaned and reused. The internal filter media becomes clogged with contaminants and loses its ability to trap particles. A clogged filter restricts oil flow and defeats the purpose of having one.
How often should I change the filter?
Check your owner's manual for the recommended interval — it's usually every 5,000 to 10,000 miles or every 3 to 12 months, whichever comes first. Some newer vehicles with synthetic oil may go longer between changes. If you change your oil, you should always change the filter at the same time.
What if oil leaks from the new filter after I install it?
Turn off the engine and wait a minute for the pressure to drop. Check that the rubber gasket is seated properly and that you haven't over-tightened the filter. Loosen it slightly, reseat the gasket, and hand-tighten it again to three-quarters of a turn past contact. Restart and recheck. If leaking continues, the gasket may be defective — replace the filter with a new one.
