The 2018 Honda Civic uses a cartridge-style oil filter inside a small canister, not a traditional spin-on filter; the exact filter number depends on whether your model has the 1.5-liter turbo or the 2.0-liter engine.
Engine options and filter type
For the 2018 Civic, the two available engines are the 1.5-liter turbo and the 2.0-liter i-VTEC. In both cases, Honda employs a cartridge-style oil filtration system housed in an oil filter housing. When you perform an oil change, you replace the filter cartridge and its sealing O-ring using a Genuine Honda oil filter kit or an equivalent OEM-approved cartridge.
Oil filter types by engine:
- 1.5L turbo (L15B7) — cartridge-style oil filter inside a housing; replacement requires a new cartridge and O-ring as part of an OEM kit.
- 2.0L i-VTEC — cartridge-style oil filter inside a housing; the replacement process and kit are the same general approach as the turbo model.
Note: While both engines use cartridge-type filters, the exact cartridge part number can vary by production date and sub-model. Always confirm the correct part using your VIN, engine code, or by checking with a Honda dealer or official parts catalog.
How to identify and obtain the right filter
To ensure you get the correct cartridge for your 2018 Civic, check the owner's manual or use Honda’s official parts lookup. You can also provide your vehicle’s VIN to a dealer or parts retailer to confirm the exact filter cartridge and gasket you need. If you prefer aftermarket options, choose a cartridge-style filter kit that explicitly states compatibility with the 2018 Civic’s engine (1.5L turbo or 2.0L) and follow the included replacement guidelines.
Before you buy, verify the engine type and the replacement method since some service centers may list compatible cartridges differently. Accuracy here helps avoid fitment issues and ensures a proper seal during operation.
Replacing the cartridge filter: a brief guide
When you service the oil, you’ll replace both the cartridge and the O-ring in the same housing. A typical DIY approach includes draining the old oil, removing the filter housing cap with the appropriate tool, pulling out the old cartridge, cleaning the housing, installing the new cartridge and O-ring, resealing the cap, and refilling with fresh oil to the vehicle’s specification. Always consult the service manual for torque specs and step-by-step instructions tailored to your exact model and engine.
Where to buy and what to ask for
Look for a Honda Genuine Oil Filter Cartridge Kit or a reputable aftermarket cartridge filter designed for the 2018 Civic’s 1.5L turbo or 2.0L engine. When shopping, ask for the cartridge-style oil filter compatible with the 2018 Civic and confirm you’re getting the correct kit (cartridge plus seal) for your engine type and production date.
Summary
In short, the 2018 Honda Civic uses a cartridge-style oil filter housed in a filter canister, with the exact cartridge number varying by engine (1.5L turbo or 2.0L). Always verify your engine type and VIN to ensure you purchase the correct cartridge kit, and follow the vehicle’s service manual or a trusted technician’s guidance when performing an oil change.
