Honda Civic 1.5T oil dilution — same as CR-V fault
The same oil dilution fault affecting the CR-V also occurs in the Honda Civic Mk10 with the 1.5 VTEC Turbo engine. Oil level increases over time and petrol smell is present. The fix involves a Honda software update to raise the engine coolant thermostat opening temperature. Owners should check oil level regularly and avoid short cold journeys. Fully synthetic 0W-20 oil as specified by Honda is critical.
