The 2018 Honda Civic uses 0W-20 fully synthetic motor oil. This applies to the common engine options in that model year, and Honda’s guidance emphasizes sticking with 0W-20 synthetic for optimal performance and protection.
Oil type and engine variants
There were two main engine options for the 2018 Civic in many regions. Honda’s official guidance is the same for both: use 0W-20 synthetic oil. The details below apply to the two common engines found in the US market for 2018 Civics:
- 2.0L i-VTEC engine (LX, EX, EX-L, Touring, and manual/transmission variants): 0W-20 full synthetic motor oil.
- 1.5L turbocharged engine (EX, EX-L, Touring, and Sport models): 0W-20 full synthetic motor oil.
Always verify the specification in your owner's manual or with a Honda dealer for your exact trim and market, as specifications can vary by region and model year, though 0W-20 is the standard recommendation for 2018 Civics in most markets.
Maintenance intervals and tips
With synthetic oil, Honda typically recommends an oil-change interval of about every 7,500 miles (12,000 kilometers) under normal driving conditions, and more frequently under severe driving conditions. Always reset the vehicle’s oil-life monitor at service intervals and use a quality oil filter in addition to the oil itself.
Notes and special considerations
For best results, use Honda-approved oil and a genuine Honda oil filter. If you cannot obtain 0W-20 in an emergency, check with a dealer or service center before using alternative viscosities. In some regions, climate conditions may influence the oil-care routine, but 0W-20 remains the standard recommendation for 2018 Civics in most markets.
Summary: The 2018 Honda Civic takes 0W-20 fully synthetic motor oil for both the 2.0L and the 1.5L turbo engines, with typical oil-change intervals around every 7,500 miles under normal driving. Always consult the owner’s manual or a dealer for your exact specifications and service schedule.
