What Causes the Increase in Engine Oil in Honda Civic?
2 Answers
Honda Civic's engine oil increase is caused by: 1. A design defect in the engine where gasoline injected into the cylinder during cold starts condenses on the cylinder wall and flows into the crankcase; 2. An unreasonable design of the engine's exhaust valve, which fails to promptly expel gasoline entering the engine. The Civic is equipped with an iVTEC engine paired with a 5AT transmission, delivering a maximum power of 115 kW. In terms of exterior design, the Civic features xenon headlights, side mirrors with turn signals, and comes in body colors such as Taffeta White, Crystal Black, Titanium Silver, Platinum White Pearl, Crystal Purple, Rallye Red, and Brilliant Sporty Blue. For suspension, the Civic uses a front MacPherson strut independent suspension and a rear double-wishbone independent suspension, significantly enhancing driving stability and ride comfort.
Having driven many Civics, the most common cause of increased oil level is fuel mixing into the oil under low-temperature conditions. Some of Honda's direct-injection engines are prone to incomplete combustion in cold weather, allowing gasoline to leak into the crankcase and dilute the oil, leading to a rise in oil level. This may be related to design flaws or ECU settings, and driving habits also play a significant role, such as frequently making short trips where the engine is started and shut off before reaching optimal operating temperature. Ignoring this issue can degrade the oil's lubricating properties, accelerate piston ring wear, and even damage the engine. It's recommended that owners in northern regions check the dipstick more often. If the oil smells like gasoline or appears thin, promptly visit a dealership for a software update. Regular maintenance can prevent problems before they arise—don't wait until a warning light appears to take action.
