Will the Honda Haoying experience engine oil dilution?
2 Answers
Engine oil will not increase unless there is incomplete fuel combustion or oil leakage. Below is more information about engine oil: Composition of engine oil: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties. Additives compensate for and improve the shortcomings of base oil performance, endowing it with certain new characteristics, making them an important part of lubricating oil. How to choose the right specification of engine oil: Select the corresponding series of engine oil based on the fuel used by the engine. Gasoline engines should use S-series oil, diesel engines should use C-series oil, and LPG engines should use LPG-specific engine oil.
I've encountered the oil dilution issue with the Honda Haoying several times, particularly in early models equipped with the 1.5-liter turbocharged engine, such as the 2018 to 2020 versions, mainly caused by fuel dilution. Simply put, gasoline leaks into the engine oil during cold starts or short-distance driving, mixing together, causing the oil level to read much higher than normal on the dipstick. I've seen many owners complain about inexplicably rising oil levels in winter, accompanied by oil vapor from the oil cap or increased engine noise. This issue isn't very common, but when it occurs, it raises concerns about engine wear, potentially exacerbating problems like piston ring wear. I think it's best to regularly check the dipstick when the engine is cold. If the level is significantly higher and smells of gasoline, take it to a dealership immediately—they sometimes offer free oil changes or software updates. Overall, this isn't a major hazard, but ignoring it for too long could shorten engine life. Honda has since optimized the design to reduce this issue.
