What oil filter your 2015 Honda Civic needs

The 2015 Honda Civic uses a Honda OEM filter (part number 15400-PLM-A01 or 15400-PLM-A02), depending on engine type. The standard replacement is a spin-on canister filter located on top of the engine, accessible from above without removing the wheel or undercarriage panels. Most aftermarket filters rated for the 2015 Civic will fit this same location and thread pattern.

The filter capacity is approximately 0.3 quarts of oil, so the total oil change (filter plus fresh oil) typically requires between 3.5 and 3.7 quarts depending on whether you're also replacing the drain plug washer. Honda recommends changing the filter every time you change the oil, not as a separate service.

Key Takeaways

  • The 2015 Civic's filter is a spin-on canister located on top of the engine, held in place by a threaded collar that turns by hand or with a filter wrench.
  • OEM Honda filters are part number 15400-PLM-A01 or 15400-PLM-A02; most common aftermarket brands (Mobil 1, Fram, Purolator, Bosch) offer equivalent replacements at lower cost.
  • Changing the filter takes 5 to 10 minutes once you've warmed the engine and drained the old oil, and requires no special tools beyond a filter wrench if the old filter is stuck.
  • The filter housing does not have a separate drain plug; oil drains from the filter canister itself, so position a drain pan directly underneath before loosening it.

Locating and accessing the filter on your Civic

Open the hood and look toward the front-center of the engine, just behind the intake manifold. The filter is a cylindrical canister roughly 3 inches tall and 2.5 inches in diameter, with a threaded base screwed into the engine block. On the 2015 Civic, it sits high enough that you can reach it with your hand or a filter wrench without removing any wheels or splash guards.

Before you touch it, run the engine for 30 seconds to warm the oil slightly. Warm oil flows more freely and helps the old filter drain faster. Turn off the engine and wait 2 to 3 minutes so the filter is warm but not hot enough to burn your hand. Place a drain pan on the ground directly under the filter to catch the oil that will spill when you loosen it.

Removing the old filter and installing the new one

Grip the filter canister with your hand or a filter wrench and turn it counterclockwise to loosen it. Once it's loose enough to turn by hand, unscrew it the rest of the way and set it aside in the drain pan. Oil will drip from the threaded base for 30 to 60 seconds, so let it drain completely before moving on.

Wipe the threaded base clean with a rag or paper towel. Check that the rubber gasket from the old filter did not stick to the engine block; if it did, remove it by hand. Dip your finger in fresh oil and coat the rubber gasket on the new filter lightly. Screw the new filter onto the threaded base by hand until the gasket contacts the engine block, then turn it an additional three-quarter turn. Do not use a wrench to tighten it; hand-tight is correct. Over-tightening can damage the gasket and cause leaks.

Aftermarket filter options and how they compare

OEM Honda filters cost between $8 and $12 per unit and are available from any Honda dealer or online retailer. Aftermarket brands rated for the 2015 Civic include Mobil 1 (synthetic, $6 to $10), Fram (standard and synthetic options, $5 to $9), Purolator (standard and synthetic, $6 to $11), and Bosch (standard and synthetic, $7 to $12). All of these use the same thread pattern and fit the same location as the OEM filter.

The main differences are filter media thickness, bypass valve opening pressure, and anti-drainback valve design. Synthetic filters generally trap smaller particles and last longer between changes, but the 2015 Civic's engine does not require synthetic oil or a synthetic filter. A standard filter changed every 5,000 to 7,500 miles (or per your owner's manual) is sufficient. If you use synthetic oil, a synthetic filter is a reasonable pairing, though not mandatory.

Common mistakes and how to avoid them

The most frequent error is over-tightening the new filter with a wrench. The rubber gasket is designed to seal at hand-tight plus three-quarter turn; tightening beyond that crushes the gasket and causes it to leak oil once the engine warms up. If you over-tighten and the filter leaks, you must remove it, clean the base again, and install a new filter with the correct torque.

A second common mistake is forgetting to remove the old gasket from the engine block. If the rubber ring sticks to the threaded base when you unscrew the old filter, it will remain on the engine. Installing a new filter with two gaskets stacked creates a poor seal and will leak. Always inspect the threaded base after removing the old filter and remove any stuck gasket by hand.

Finally, some owners install the new filter before draining all the old oil from the housing. This causes the drain pan to overflow and makes a mess. Always let the old filter drain for at least 30 seconds before installing the new one, and keep the drain pan positioned underneath the entire time.

Tools and materials you'll need

A filter wrench is optional but helpful if the old filter is stuck tight. Common styles include a strap wrench (adjustable, works on any size) or a socket-style wrench (sized for the Civic's filter). A strap wrench costs $8 to $15 and works on multiple filter sizes if you service other vehicles. A socket wrench costs $5 to $10 but only fits the 2015 Civic's filter size.

You will also need a drain pan (any container that holds at least 1 quart), fresh oil (3.5 to 3.7 quarts of the grade specified in your owner's manual), rags or paper towels, and a new filter. Some owners also replace the crush washer on the drain plug during an oil change, which requires a new washer (less than $1) and a wrench to fit your drain plug bolt. Check your owner's manual for the correct oil grade and drain plug washer size before you start.

Frequently Asked Questions

Can I use any spin-on filter that fits the thread pattern?

Most spin-on filters with the same thread pattern will physically fit, but not all are designed for the 2015 Civic's engine. Filters rated for the 2015 Civic by the manufacturer (Honda, Mobil, Fram, Purolator, Bosch) have been tested for flow rate and bypass pressure. Using an unrated filter may restrict oil flow or open the bypass valve at the wrong pressure, reducing engine protection. Stick to filters explicitly listed as compatible with the 2015 Civic.

What should I do with the old filter after I remove it?

The old filter contains used oil and should be recycled, not thrown in the trash. Many auto parts stores (AutoZone, O'Reilly, Advance Auto Parts) accept used filters for free. Some recycling centers and municipal hazardous waste facilities also take them. Drain as much oil as possible into your drain pan before dropping off the filter, and place it in a bag to prevent spills during transport.

How often should I change the filter on a 2015 Civic?

Honda recommends changing the filter every time you change the oil. For a 2015 Civic, that is typically every 5,000 to 7,500 miles with conventional oil, or every 7,500 to 10,000 miles with synthetic oil, depending on driving conditions. Check your owner's manual for the exact interval for your vehicle and driving habits.

Is the filter location the same on all 2015 Civic trim levels?

Yes. The 2015 Civic sedan, coupe, and hybrid all use the same filter location on top of the engine. The filter part number is the same across all gasoline engine variants (15400-PLM-A01 or 15400-PLM-A02). The hybrid model uses a different engine but the same filter mounting location and accessibility.
