Can 92 Octane Gasoline Be Mixed with 95 Octane?
2 Answers
92 octane gasoline cannot be mixed with 95 octane. Long-term mixing may cause engine knocking, insufficient power, and increase the frequency of knocking, thereby accelerating engine wear. Therefore, it is more scientific, economical, and efficient to refuel according to the engine's compression ratio or the requirements specified in the vehicle's manual. The octane rating of gasoline represents its anti-knock quality. For example, 92 octane gasoline consists of 92% isooctane (which has good anti-knock properties) and 8% n-heptane (which has poor anti-knock properties). The higher the octane number, the higher the isooctane content, indicating better anti-knock performance of the gasoline.
As a netizen who frequently shares car tips, I've found that cars designed for 92-octane gasoline can temporarily use 95-octane fuel without issues. The higher octane rating of 95-octane provides better anti-knock performance, sometimes making the engine run smoother. I've tried switching to 95-octane during long-distance drives or in hot weather, noticing slightly quicker acceleration, reduced noise, and a more comfortable driving experience. This adjustment isn't necessary since 92-octane already meets the vehicle's requirements, offering better cost performance and savings. Using 95-octane won't harm the engine and may even have a slight cleaning effect. However, long-term use isn't cost-effective, as the extra expense doesn't yield noticeable differences. I recommend trying it occasionally for a change.
