The oil filter number most commonly used on a 2012 Honda Civic with the 1.8-liter engine is Honda part number 15400-PLM-A02. Depending on the exact build date and market, you may encounter similar numbers such as 15400-PLM-A01 or 15400-PLM-A03. Always verify the correct part for your vehicle to ensure a proper fit.
Honda Civics from 2012 predominantly use the 1.8L four-cylinder engine. The oil filter is a replaceable part that must match the engine’s thread size and can vary by production run or region. Mobil 1 refers to the oil brand you may choose to use; it does not dictate the filter number, but selecting a compatible, high-quality filter is important when using any brand of oil. If you’re using Mobil 1 oil, pairing it with the correct filter for the 1.8L Civic helps maintain performance and longevity.

Mobil 1 oil: context for filter choice
Mobil 1 is a widely used synthetic motor oil brand. The oil type you choose (for example, 0W-20 or 5W-20, as recommended by Honda for many Civics of this era) does not change the required oil filter number. Nevertheless, using a high-quality, properly fitting filter is essential when you use Mobil 1 or any other brand of oil. Always confirm the recommended oil grade in your owner's manual or under the hood sticker when using Mobil 1.
How to verify the exact part for your vehicle
There are several reliable ways to confirm the precise oil filter number for your car:
- Check the current filter for a printed part number.
- Enter your vehicle’s VIN in Honda’s official parts portal or ask a dealership to pull the exact match.
- Provide year, make, model, and engine details at a parts retailer to cross-reference compatible filters.
Providing your VIN or engine code (for example, the 1.8L variant) helps ensure accuracy when ordering parts.
What to tell a mechanic or parts counter
When shopping, supply the year, model, trim, engine, and, if possible, the VIN. If you plan to use Mobil 1 oil, mention the intended oil grade and viscosity to help ensure the filter selection aligns with the oil change interval and engine requirements.
Summary: For a 2012 Honda Civic with the common 1.8L engine, the typical oil filter number is 15400-PLM-A02, though 15400-PLM-A01 or 15400-PLM-A03 may appear depending on the build. Always verify via VIN-based parts lookup or by inspecting the current filter. Mobil 1 oil can be used with the correct filter; the oil brand does not change the filter number, but using the recommended oil grade is important.
