有些北美燃油专家的意见如下，供参考：
The main advantage of premium-grade gas is that it allows automakers to advertise a few more horsepower by designing and tuning engines to take advantage of premium's anti-knock properties. But auto engineers generally agree that if you use regular in a premium engine, the power loss is so slight, most drivers can't tell.
使用高标号汽油的主要好处是汽车厂家可以利用高标号汽油的抗爆震性把发动机设计得调校得马力大一点，这点增加的马力可以让厂家做广告。但是汽车工程师总的说来同意一点：如果在本来用高标号汽油的车里加87号时，动力的损失很少，大多数的驾车人觉察不到。
ll Porsche engines are designed for premium, too, but it's not available everywhere. "Our cars must be able to drive all over the world, and so we are able to run on regular," says Jakob Neusser, director of powertrain development at Porsche's research and development center in Weissach, Germany. "You don't have to feel that a mechanical problem or anything else will happen" using regular gas, even in the highest-performance, regular-production Porsches.
所有保时捷的引擎也是以高标号汽油而设计的，但是高标号油不是哪里都有的，“我们的车必须在全世界都能开，所以我们能够用普通油”，位于德国威谐的保时捷研发中心主管动力驱动系发展的Weissach说。
Premium, in fact, sometimes is worse fuel than regular. It resists knock because it's harder to ignite than lower-octane fuels. As a result, some engines won't start as quickly or run as smoothly on premium, notes Gibbs, the SAE fuel expert.
高标号油实际上有时候比低标号的还差，高标号能抗爆震是因为它比低标号的燃油难点燃，结果一些引擎着车比用低标号的慢，而且没低标号的平顺，美国汽车工程师学会的Gibbs写道。
No data show that engines designed strictly for regular run better or longer on premium.
没有数据表明严格为低标号汽油而设计的引擎用高标号油会运转得更好寿命更长。
The Federal Trade Commission, in a consumer notice, emphasizes: "(I)n most cases, using a higher-octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner."
联邦贸易委员会在一份消费者通知中强调“在大多数情况下，用比你的手册里建议的标号高的油绝对没有好处。它不会让你的车跑得更好更快，更省油或者更清洁”

不过有一点，偶尔使用除碳油的话，效果确实不错，动力也恢复不少。
有一样经历的，在此举个手吧！ |
