What to Do If a Vehicle Requires 95 Octane Fuel but 92 Octane Was Added?
1 Answers
If 92 octane gasoline is within the manufacturer's recommended fuel grade range, then switching from 95 octane to 92 octane is not a problem; however, if the manufacturer recommends 95 octane fuel, 92 octane should not be used. More information about 95 and 92 octane fuels is as follows: 1. 92 octane gasoline has an octane rating of 92 and contains 8% n-heptane, making it suitable for mid-range vehicles (with relatively low compression ratios). On December 18, 2013, the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China jointly issued the fifth-stage national standard for automotive gasoline: "Automotive Gasoline." 2. 95 octane gasoline consists of 95% isooctane and 3% n-heptane. High-octane fuel should be used for engines with high compression ratios. Using low-octane fuel in high-compression engines can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving performance. Of course, modern high-compression engines can also use lower-octane fuel, but one should not blindly choose fuel based solely on compression ratio. It is best to follow the manufacturer's recommendations for fuel selection.
