The Mazda CX-5 uses a cartridge-style oil filter housed in a dedicated filter housing, not a traditional spin-on canister. The exact cartridge you need depends on your engine option and model year; confirm the correct filter by checking your engine code and referring to Mazda’s official parts catalog or your owner’s manual.
Engine options and filter design
Across generations, Mazda migrated to the SKYACTIV engine family, and all CX-5s use a cartridge-type filter inside a housing. Here’s how the filter setup typically aligns with common CX-5 engines.
- 2.0L SKYACTIV-G (earlier or market-specific models): cartridge-style filter within a housing.
- 2.5L SKYACTIV-G (most markets): cartridge filter in a housing; replacement involves the cartridge element.
- 2.5L Turbo SKYACTIV-G (higher trims and newer years): cartridge filter in a housing, same replacement approach.
- 2.2L SKYACTIV-D (diesel options in some markets): cartridge filter in a housing; the cartridge is the component to replace.
Note that engine availability and filter design can vary by country and model year. Always verify with your VIN or the official Mazda catalog to avoid ordering the wrong part.
How to identify the correct oil filter part number
To ensure you get the right oil filter cartridge for your CX-5, use these steps to identify the exact part number.
- Check the engine code and model year listed on the vehicle’s information placard or in the owner’s manual.
- Look up the OEM Mazda oil filter cartridge in the Mazda Parts catalog or on Mazda’s official parts site using your VIN or engine code.
- When purchasing aftermarket, choose a cartridge-style oil filter designed for Mazda SKYACTIV engines and confirm compatibility with your exact engine and year.
Concluding note: Mazda’s cartridge-style oil filter design simplifies replacement but requires replacing only the cartridge, not a full canister, for most models. If you’re unsure, consult a dealer or a trusted independent shop to confirm the correct part for your CX-5’s engine.
Procedure and maintenance tips
Before performing oil changes, prepare the tools and ensure you have the correct cartridge filter. Here is a general guide to replace the cartridge filter in a CX-5’s engine.
- Warm the engine briefly, then turn off and secure the vehicle for access to the oil filter housing.
- Place a drain pan under the engine and remove the drain plug to drain engine oil.
- Remove the filter housing cap to access the cartridge. Note how the O-ring sits.
- Remove the old cartridge, wipe the housing, and install a new cartridge with a fresh O-ring or gasket as specified by Mazda.
- Reassemble the housing, lubricate the O-ring with a thin film of fresh oil, reinstall the drain plug, and fill with the correct amount of fresh oil stated in the owner’s manual.
Final reminder: Always replace the filter cartridge with the correct part and use the right oil grade for your engine. If you have a warranty or service plan, have a professional perform the oil change to maintain coverage.
Summary
The CX-5 uses a cartridge-style oil filter inside a dedicated housing. The exact cartridge depends on the engine option (2.0L, 2.5L, 2.5T, or diesel in some markets) and model year. Confirm the right part by checking the engine code, VIN, or Mazda’s official parts catalog, and replace only the cartridge where applicable to complete an oil change correctly.
