The 2013 Honda Civic 2.4L engine (Civic Si) uses SAE 5W-20 engine oil as the standard viscosity, with synthetic or synthetic-blend formulations preferred. Oils should meet API SN or newer and ILSAC GF-5 or GF-6 specifications. In very cold climates, 0W-20 can be used if permitted by the owner's manual. Always verify the exact specification for your trim in the manual or with a dealer.

Brand considerations
While any reputable oil meeting the specified standards will work, many owners opt for well-known brands and Honda-recommended oils. Using a trusted brand and a fresh oil filter helps maintain proper engine protection and performance.
Maintenance and oil-change intervals
Oil-change schedules vary by oil type and driving conditions. Synthetic oils typically allow longer intervals than conventional oils, but you should follow the maintenance minder and the owner’s manual for exact timings.
- Conventional oil: commonly around 3,000–5,000 miles (4,800–8,000 km) depending on conditions.
- Synthetic or synthetic-blend oil: commonly around 5,000–7,500 miles (8,000–12,000 km) or longer under normal driving.
- Severe service conditions (short trips, heavy loads, extreme temperatures): shorten intervals accordingly.
Bottom line: Always adhere to the recommended interval in the owner's manual or maintenance minder and adjust for your driving habits and climate.
