Honda Civic Si maintenance: the schedule, the costs, the traps
A sport compact sedan with a gas powertrain. Below: the service intervals with real cost ranges, the repairs Civic Si owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Known repair windows
What Civic Si owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
Clutch wear-out (6MT only)
medium severity40,000-90,000 mi · $1,200-$1,900
Wear item; aggressive launches / track days shorten life dramatically.
1.5L turbo oil dilution
low severity5,000-60,000 mi · $0-$500
Less prevalent on Si (spirited driving burns fuel off), but still monitor oil level.
Turbocharger wastegate/actuator
medium severity80,000-140,000 mi · $900-$1,800
Higher-boost tune stresses turbo; oil-change discipline is key.
A/C condenser leak
medium severity40,000-90,000 mi · $550-$1,100
Standard Honda condenser weak spot.
Operator notes
Performance Civic: 200-hp 1.5L turbo, standard 6-speed MANUAL with helical limited-slip and rev-match. No CVT, no timing belt (chain). Brake fluid should be flushed more often (yearly) if tracked. Full synthetic 0W-20.
When the smart money sells
On fleet math, a gas Civic Si retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
