但我们这儿油87和89一个价
就随便加了 感觉没区别
哪个好点？
从压缩比和油耗上来说 |

抗爆 89 is slightly better.
油耗 same

还有说 现在的机器会自己调整点火角度 自己能适应
弄不清了
你的意思是说89好一点么？

说有劲 当然是公家车 油钱不是问题
原因可能是国内的油品问题
不知道这边怎么样 |

compression ratio, car manual will tell you to use premium (91 or higher)
gas
if your car only requires 87, then use 87 is fine. if you use 91 in an
engine that only requires 87, then it's possible to have 燃烧不充分
and the other way around is also true, if your engine requires 91 and you
use 87, then you can experience knocking, aka 爆震
and also true, engine has knock sensor, and can adjust it's timing. but in
that case you are hurt
