Can 95 and 98 gasoline be mixed together?
2 Answers
95 and 98 gasoline cannot be mixed. The following are specific introductions to car refueling: 1. Gasoline grade description: Although 98 gasoline has higher anti-knock performance and power, vehicles with low grades should not blindly choose high-grade gasoline. The higher the grade, the more suitable it is for engines with larger compression ratios. The engines of cars that use 95 gasoline often have smaller compression ratios. Adding 98 gasoline may increase knocking in the engine. 2. Avoid mixing: Gasoline of different grades should not be mixed, such as mixing 98 and 95 gasoline. However, long-term use may also have a certain impact on the engine, and even cause phenomena such as engine carbon deposits and increased fuel consumption.
Well, I have quite a bit of experience to share about mixing 95 and 98 octane gasoline. As someone who often helps friends with car repairs, I can confidently say that occasional mixing is fine—engines aren’t that delicate. 95 octane has weaker anti-knock performance, while 98 is stronger. Mixing them is like drinking different brands of coffee; the machine can adjust and adapt. However, I don’t recommend long-term mixing, especially if your car’s manual suggests using 95 octane. Regularly adding 98 octane might cause the engine to ignite prematurely. While not fatal, it increases the risk of knocking and, over time, could lead to more carbon buildup, affecting fuel efficiency and performance. Honestly, everyone wants to save money, but if you truly care about your car, stick to the manual’s recommended single fuel grade to avoid trouble. If knocking does occur, repairs won’t be cheap—you’ll end up losing more in the long run.
