The right oil filter depends on which engine your 2018 Civic has: the 2.0L i‑VTEC engine or the 1.5L turbo. For the two engines, the corresponding Honda Genuine oil filters are 15400-PLM-A01 (2.0L) and 15400-PLM-A02 (1.5L turbo).
In 2018, the Civic lineup offered two engine options. The correct filter is tied to your specific engine variant, and the part numbers above come from Honda’s official catalog. To be certain, check your VIN, the engine code under the hood, or the current filter itself before purchasing.
Engine options in the 2018 Civic
The 2018 Civic was offered with a naturally aspirated 2.0-liter engine for base trims and a turbocharged 1.5-liter engine for higher trims. Both variants use a standard spin-on oil filter, and Honda recommends using Honda Genuine oil and filters for optimal performance. If you’re unsure which engine your car has, you can identify it by checking the engine code on a label under the hood or by reviewing your vehicle’s documentation.
2.0L i‑VTEC engine
The 2.0L engine typically uses Honda Genuine Oil Filter part number 15400-PLM-A01. This number is listed in Honda’s official parts database as the appropriate filter for the 2.0L Civic from model years around 2016–2019.
1.5L turbo engine
The 1.5L turbo uses Honda Genuine Oil Filter part number 15400-PLM-A02. This filter is designed for the turbocharged variant across the same general production window.
How to confirm the correct filter
Before you buy, verify with one of the following methods to avoid errors:
- Consult the owner's manual or the service manual for the exact part number.
- Use Honda’s official Parts Catalog online and input your VIN or engine code.
- Compare the current filter on your engine to the part numbers printed on the OEM filter or in the parts catalog.
Using the exact OEM filter ensures proper fit and filtration and helps maintain warranty coverage.
Where to buy
Honda dealerships stock these filters, and many aftermarket brands offer compatible options with correct cross-references. When shopping aftermarket, ensure the product specifies compatibility with the 2.0L or the 1.5L turbo variant of the 2018 Civic, depending on your engine.
Summary
Bottom line: the 2018 Honda Civic requires different oil filters depending on the engine. Use Honda Genuine Oil Filter 15400-PLM-A01 for the 2.0L engine and 15400-PLM-A02 for the 1.5L turbo. Always verify with your VIN, engine code, or the current filter to ensure you buy the correct part, and consult the owner's manual or a trusted parts catalog if you’re unsure.
