Is There Any Benefit to Occasionally Using 95 Octane Gasoline for Your Car?
2 Answers
Occasionally using 95 octane gasoline offers the following benefits for your car: Higher Efficiency: 95 octane gasoline is purer and of better quality, containing more isooctane. As a result, vehicles using 95 octane gasoline exhibit significantly better anti-knock performance, allowing the gasoline to burn more completely and efficiently. Environmental Protection: It helps reduce pollutant emissions from motor vehicles. New vehicles can see reductions in nitrogen oxide and particulate emissions by 25% and 80% respectively, while in-use vehicles can achieve an overall emission reduction of 10%-15%. This plays a significant role in protecting the environment and improving air quality.
As a veteran driver with fifteen years of experience, let me talk about refueling. It all depends on your car's appetite. If the manual says to use 92, don't assume 95 is somehow superior—the difference in anti-knock properties is negligible for regular engines. Once, out of curiosity, I filled up my old car with 95 and noticed no improvement in power or fuel efficiency. However, I've heard that turbocharged engines might benefit from occasional premium fuel to reduce knocking, but only if the compression ratio allows. The most practical advice is to stick to the number on the fuel cap. If you really want to improve engine performance, regular maintenance is far more effective.
