This applies to the common 1.8L i-VTEC (R18A1) configuration found in most 2012–2015 Civics. Production variations exist, so it’s wise to confirm the exact part by checking the current filter, VIN, or official Honda parts catalog if you’re unsure.
How to confirm the correct filter for your Civic
Use these steps to verify the right filter before purchasing or replacing it.
- Check the part number on your current oil filter to ensure it matches 15400-PLM-A02, if possible.
- Use your vehicle’s VIN to pull up the correct parts in Honda’s official catalog or through a dealership parts system that supports VIN lookup.
- Consult the owner’s manual or service section for the recommended filter number for your specific trim and production date.
- If purchasing online or at an auto parts store, ask for a filter listed as compatible with the 2012–2015 Civic with the 1.8L engine (R18A1) to cover the likely variant.
Following these steps helps ensure you obtain the correct filter and avoid compatibility issues.
OEM vs. aftermarket options and installation tips
Honda Genuine 15400-PLM-A02 is the confirmed OEM option for the 2015 Civic LX. Many reputable aftermarket filters advertise compatibility with the 1.8L Civic (R18A1) from 2012–2015, but always verify before purchase.
- Look for aftermarket filters that explicitly state compatibility with the 1.8L Civic (R18A1) and the model years 2012–2015.
- Avoid filters that do not specify engine compatibility or that omit the 1.8L Civic from the listing.
- When switching brands, confirm the thread size and gasket diameter to ensure a proper seal.
When installing any new filter, lightly oil the gasket with clean engine oil and hand-tighten. Do not over-tighten, and replace the oil simultaneously according to your maintenance schedule.
Summary
For a 2015 Honda Civic LX, the recommended oil filter is Honda part number 15400-PLM-A02. Always verify with the VIN or by inspecting the current filter, and consider a reputable aftermarket option that clearly lists compatibility with the 1.8L Civic (R18A1) if you choose not to use the OEM part. Regular maintenance with the correct filter helps keep the engine running smoothly.
