Can 95 and 98 gasoline be mixed together?
1 Answers
It is not recommended to mix 95 and 98 gasoline. If the car owner has been using 95-octane gasoline, adding 98-octane gasoline once or twice will not have a significant impact, but long-term mixed use is not advisable. If the car owner intends to switch gasoline grades, it is recommended to wait until the fuel gauge light comes on before refilling with the new grade, or to directly extract the remaining gasoline and then switch to the new grade, rather than mixing them directly. The naming of 95 and 98 gasoline actually refers to the ratio of the gasoline's anti-knock performance to that of standard gasoline. For example, 95-octane gasoline contains 95% isooctane and 5% n-heptane, while 98-octane gasoline has higher anti-knock performance than 95-octane gasoline.
