What oil filter your 2012 Accord needs and where it sits

The 2012 Honda Accord uses a cartridge-style oil filter housed in a plastic canister on top of the engine. This is different from the spin-on filters on many other vehicles — you don't unscrew a cylindrical filter from the side of the engine. Instead, you remove a cap, pull out the filter element, and replace it with a new one.

The filter canister sits near the front of the engine, toward the passenger side. On the 2.4-liter four-cylinder engine (standard in most 2012 Accords), it's mounted directly on top of the valve cover. On the 3.5-liter V6 model, the location is similar but slightly offset. Both are straightforward to reach without removing other parts.

Honda part number 15400-PLM-A02 is the OEM (original equipment manufacturer) filter for the 2012 Accord. Many aftermarket filters also fit — Fram, Mobil 1, Purolator, and Bosch all make compatible cartridge filters. Check the box or product page to confirm it's listed for a 2012 Accord before you buy.

Key Takeaways

  • The 2012 Accord uses a cartridge-style filter in a canister on top of the engine, not a spin-on filter you unscrew from the side.
  • You'll need a filter wrench (usually a 74mm or 86mm socket-style wrench) to remove the canister cap, plus a new filter element and a new rubber gasket.
  • The job takes 10 to 15 minutes and requires only basic tools — no special equipment or lifting the vehicle is necessary.
  • Always replace the rubber gasket that seals the canister cap, because reusing the old one can cause leaks.

Tools and parts you'll need before you start

Gather these items before you open the hood. You'll need a filter wrench to remove the canister cap — this is a socket-style wrench, usually 74mm or 86mm depending on engine size. A regular adjustable wrench won't grip the cap well enough. Most auto parts stores rent filter wrenches for a few dollars, or you can buy one for $10 to $20.

You'll also need the replacement filter element itself, a new rubber gasket (this comes with most filter kits but not all — check before you leave the store), fresh oil to top off the engine after the change, an oil drain pan to catch spills, and rags or paper towels. If you don't have a drain pan, a shallow baking pan or old roasting pan works in a pinch.

Some people use an oil filter socket wrench instead of a cap wrench — this is a deep socket that grips the canister cap from the outside. Either tool works. If you're doing this job only once, renting is cheaper than buying.

Step-by-step removal and replacement

Step 1: Warm the engine and locate the canister. Start the engine and let it run for 30 seconds to a minute, then turn it off. Warm oil flows more easily than cold oil. Wait a minute for the engine to cool slightly so you don't burn your hands. Open the hood and locate the filter canister — it's the plastic cylinder on top of the engine with a cap on top.

Step 2: Position your drain pan and remove the cap. Place your drain pan underneath the canister to catch oil drips. Use your filter wrench to turn the cap counterclockwise. It will loosen and unscrew by hand once the wrench breaks it free. Remove the cap completely and set it aside on a clean rag.

Step 3: Remove the old filter element and gasket. Inside the canister you'll see the cylindrical filter element. Pull it straight out — it may be stuck slightly, so wiggle it gently if needed. Once the element is out, look at the rubber gasket stuck to the underside of the cap. Peel it off and discard it. Do not reuse this gasket.

Step 4: Clean the canister and install the new gasket. Wipe the inside of the canister with a clean rag to remove any debris or old oil residue. Take the new rubber gasket and press it firmly onto the underside of the cap, centering it on the flat surface. The gasket should sit flat with no wrinkles or folds.

Step 5: Insert the new filter element. Slide the new filter element into the canister, pushing it down until it seats fully. You should feel a slight resistance as it bottoms out. Don't force it — it should slide in smoothly.

Step 6: Reinstall the cap and check for leaks. Screw the cap back onto the canister by hand first, then use your filter wrench to tighten it. Tighten firmly but do not over-tighten — you're aiming for snug, not maximum force. Over-tightening can crack the plastic canister or damage the gasket.

Step 7: Top off the oil and run the engine. Check your oil level with the dipstick and add oil if needed to bring it to the full mark. Start the engine and let it run for a minute, watching the area around the filter cap for any drips. If you see oil leaking, turn off the engine, let it cool for a minute, and tighten the cap slightly more. Once the engine has run, turn it off and wait five minutes, then check the oil level again and top off if necessary.

Common mistakes that cause leaks or damage

The most frequent error is reusing the old rubber gasket. This gasket compresses and hardens over time and won't seal properly a second time. Even if it looks fine, replace it every time. A new gasket costs a dollar or two and prevents a messy leak.

Over-tightening the cap is the second common mistake. The plastic canister is not as strong as a metal filter housing on other vehicles. Tighten the cap until it's snug, then stop. If you use a wrench and explore heavy force, you risk cracking the canister itself, which is an expensive repair. Hand-tight plus a quarter turn with the wrench is usually correct.

Forgetting to check the oil level after the job is also common. The new filter holds a small amount of oil, so your dipstick reading will drop slightly. Top it off to the full mark to avoid running the engine low on oil.

When to replace the filter during an oil change

Honda recommends changing the oil filter every time you change the oil. For a 2012 Accord, that's typically every 5,000 to 10,000 miles depending on driving conditions and the type of oil you use. Check your owner's manual for the exact interval for your vehicle.

If you're doing an oil change yourself, replace the filter at the same time. If you're having the oil changed at a shop, confirm that the filter replacement is included in the quoted price — some shops charge extra for the filter, and others include it.

Disposal of the old filter and used oil

Do not throw the old filter in the trash. Oil filters contain residual oil and are considered hazardous waste in most places. Take the old filter to an auto parts store — most accept them for free, and many will also take used oil. Alternatively, check your local waste management website for a hazardous waste collection day in your area.

Used oil should also be disposed of properly. Never pour it down a drain or onto the ground. Most auto parts stores accept used oil in any container, and many service stations will take it as well. Some municipalities have collection events where you can drop off oil for free.

Frequently Asked Questions

Can I change the filter without changing the oil?

Yes, you can replace just the filter if you want to. However, Honda recommends changing them together, and most people do both at the same time since you're already under the hood. If you change the filter alone, you'll still need to top off the oil level afterward because the new filter holds a small amount.

What size wrench do I need for the filter cap?

Most 2012 Accords use a 74mm filter wrench for the four-cylinder engine and an 86mm wrench for the V6. Check your owner's manual or call an auto parts store with your VIN to confirm the exact size before you rent or buy a wrench. Using the wrong size can strip the cap.

How tight should the cap be when I reinstall it?

Tighten the cap until it's snug, then add about a quarter turn more with the wrench. You should not need to explore heavy force. If the cap is hard to turn or you feel strong resistance, stop — you're tight enough. Over-tightening can crack the plastic canister.

What if oil leaks from the cap after I reinstall it?

Turn off the engine and wait five minutes for it to cool. Check that the rubber gasket is seated properly under the cap — sometimes it shifts during installation. If the gasket looks crooked, remove the cap, reseat the gasket, and reinstall the cap. If it still leaks, the gasket may be defective. Replace it with a new one and try again.

Do I need to reset any warning lights after changing the filter?

No. The 2012 Accord does not have an oil filter change reminder light. Some newer models do, but yours does not. You only need to reset the oil change reminder light if your car has one, and that's done through the instrument cluster menu — it's not related to the filter change itself.
