Can I mix half 92 and half 98?
1 Answers
92 and 98 cannot be mixed. Hazards of mixing gasoline: If the vehicle model specifies high-octane gasoline, long-term use of low-octane gasoline is not allowed, as it will increase the frequency of knocking and aggravate engine wear. Gasoline octane ratings: Gasoline has a high octane number (anti-knock combustion performance) and is divided into grades such as 89, 90, 92, 93, 95, 97, and 98 based on the octane number. Starting from January 2012, gasoline grades 90, 93, and 97 were revised to 89, 92, and 95.
