The Risks of Overfilling
While less common, overfilling your engine oil can be just as damaging. Many DIYers think “more is better,” but that’s not the case here.
- Oil Aeration: The crankshaft can dip into the excess oil, whipping it into a froth. This aerated oil is less effective at lubricating, leading to increased wear.
- Seal Damage: Excess oil creates higher pressure within the crankcase, which can blow out seals and gaskets, leading to expensive oil leaks.
- Catalytic Converter Damage: Overfilled oil can get into the PCV (Positive Crankcase Ventilation) system, leading to oil burning and potentially clogging or damaging your catalytic converter.
- Spark Plug Fouling: Burning oil can foul spark plugs, causing misfires and reduced engine performance.
Maintaining the correct **2012 Honda Civic 1.8 oil capacity** ensures your engine components are properly lubricated, cooled, and cleaned, extending its lifespan and maintaining peak performance.
