Can I add 95 gasoline when 92 is not yet used up?
1 Answers
92 gasoline can be mixed with 95 gasoline when it is not yet used up, but it is not recommended to mix gasoline for a long time as it may affect the performance of the car. If the car is only mixed with gasoline once or twice, it will not affect the normal use of the car. However, long-term mixing may cause knocking, insufficient power, and other issues. If the standard fuel grade for the car is 92, long-term mixing with 95 gasoline may cause carbon deposits in the engine due to prolonged operation. The gasoline grade represents the octane number of the gasoline. For example, 92 gasoline contains about 92% isooctane, while 95 gasoline contains about 95% isooctane. Since isooctane has better anti-knock properties, higher-grade gasoline has a higher octane number and better anti-knock performance.
