Honda Civic Parts, Specs and Maintenance Guide

The Honda Civic is the best-selling compact car in America, and the 2012–2025 span covers three mechanically distinct generations that all take 0W-20 oil, a Group 51R battery, and the same ubiquitous 15400-PLM-A02 spin-on oil filter. 4L K24 Si. Cheap to run, with AC compressor clutches and front engine mounts as the main wear items.

5T L15B7 brought big fuel economy but also documented cold-climate oil dilution (2016–2018, warranty-extended) and a leak-prone AC condenser that Honda covers for 10 years under TSB 19-091; 2018–2020 cars are also caught in the giant Denso fuel-pump recalls (20V-314/23V-858). 5T, adds a 200-hp hybrid for 2025, and its one headline defect. 'sticky steering', was fixed by recall 24V-744 in late 2024.

Unlike fixed-interval brands, every modern Civic uses Honda's Maintenance Minder: the car computes oil life itself (typically 7,500–10,000 miles per change) and displays codes (A/B plus sub-codes) telling you exactly what's due, so owners constantly look up what the codes mean, which oil to buy (always 0W-20 for these years), and how to reset the wrench light.
