How long does gasoline take to deteriorate?

Gasoline shelf life varies from a few months to several years depending on storage conditions and the type of fuel used. There are two key points to note when refilling engine oil: 1. When selecting engine oil: It must strictly comply with the oil grade specified in the vehicle's user manual. If the same grade is unavailable, you may use a higher-grade oil, but never substitute with a lower-grade one; 2. When adding engine oil: The oil quantity should be slightly below the standard mark. Excessive oil increases crankshaft rotation resistance, reduces engine output power, and may cause oil to enter the combustion chamber, leading to oil burning, blue smoke emission, and increased fuel consumption.
