The Honda Civic uses different fluids depending on the transmission type: automatic transmissions typically require Honda Automatic Transmission Fluid DW-1 (older Civics used Z1), CVT transmissions require Honda CVT Fluid HCF-2, and manual transmissions use Honda Genuine Manual Transmission Fluid (MTF).
Since Civics span many generations, the exact fluid specification can vary by model year and drivetrain. Always check your owner's manual or the transmission dipstick/label to confirm the correct fluid and viscosity for your specific Civic.
Common transmission fluids by transmission type
The following list summarizes the main fluid types you’ll encounter depending on your Civic’s transmission. Use the one that matches your model year and transmission configuration.
- Automatic transmissions (non-CVT): Honda Automatic Transmission Fluid DW-1 is standard on recent Civics; older Civics used ATF Z1.
- CVT transmissions: Honda CVT Fluid HCF-2 is specified for most Civics equipped with a continuously variable transmission.
- Manual transmissions: Honda Genuine Manual Transmission Fluid (MTF), typically meeting GL-4 specifications, is used in Civics with manual gearboxes.
Choosing the correct fluid is essential for smooth shifting, proper clamping pressure, and overall transmission longevity. If you’re unsure about your Civic’s transmission type or the exact specification, consult the owner’s manual or contact a Honda service professional.
Model-year considerations
Automatic transmissions (non-CVT)
Most Civics built in the 2010s and later use DW-1 for automatics. Some earlier models (roughly pre-2010) used Z1; when in doubt, verify the specific requirement for your year and transmission code.
CVT transmissions
CVT-equipped Civics (common in 1.5L turbo and newer generations) use CVT Fluid HCF-2. Always confirm the exact specification for your vehicle’s year, as there can be minor revisions.
Manual transmissions
Manual Civics typically require Honda Manual Transmission Fluid (MTF) that meets the manufacturer’s GL-4 standard. Verify viscosity and any year-specific notes in the manual.
Summary
In short, Honda Civics use DW-1 for most automatics, HCF-2 for CVT models, and Honda MTF for manuals. Because fluid requirements can shift between generations and even between trim levels, always verify the exact specification in your owner’s manual or on the transmission information label under the hood. Regular checks and using the correct fluid help maintain smooth shifting and extend transmission life.
