In brief, the 2012 Honda Civic uses a standard spin-on oil filter. The exact filter depends on the engine variant: 1.8-liter models and the 2.4-liter Si.
Identifying the correct filter by engine
The Civic lineup for 2012 includes two main engine options. Civics with the 1.8-liter i-VTEC engine (LX, EX) share a common spin-on filter, while the Si uses a larger 2.4-liter engine with a different filter specification. To ensure you buy the right part, confirm your engine type and then use the corresponding part number from Honda’s official parts catalog or a trusted retailer.
- 1.8L engine (LX/EX): Honda Genuine Oil Filter part number 15400-PLM-A01.
- 2.4L engine (Si): Honda Genuine Oil Filter part number 15400-RAA-A01.
Use only filters that meet OEM specifications for proper filtration, oil flow, and pressure. If you’re using an aftermarket filter, ensure it’s explicitly rated to fit the 2012 Civic’s engine and oil capacity.
Where to buy and how to confirm
To be certain you’ve got the correct filter, check your vehicle’s VIN or consult the owner's manual. You can also pull the existing filter from the engine bay and compare labeling or thread fit with the replacement. Shops and online catalogs will show compatibility by year, make, model, and engine code.
Installation reminders
When replacing the filter, follow standard procedure: replace the O-ring on the filter, apply a light coat of clean oil on the gasket, tighten by hand until snug, then give a final 3/4 turn with a filter wrench if required. Refill with the recommended oil type and amount, start the engine, and check for leaks.
Summary
The 2012 Honda Civic uses a conventional spin-on oil filter. The exact part depends on the engine: 1.8L LX/EX models use Honda filter 15400-PLM-A01, while the 2.4L Si uses Honda filter 15400-RAA-A01. Verify via VIN or the owner's manual, and replace with an OEM or OEM-equivalent filter to ensure proper filtration and oil pressure.
