我是有聽人家說拉,但我自己也騎車or 開車去加XD 壓縮問題是說,因為98較難點爆,不過要碰到引擎點不然蠻難的 低辛烷值會爆震的原因是,還沒點火,燃油就自己爆了..... 要引擎適應就要提前點火,導致不是最佳時間,效能會降低 就以這個理論,就已經可以證明98會有更高出力(不一定省錢) 我汽車(FORD ACTIVA LIFE)壓縮比9.0也是加98 你可以去看看shell(貝殼)外國網站上,對v-power(RON98)的介紹 Shell V-Power can be used in any car designed to run on unleaded petrol (except that some pre-1986 cars will also require the use of an anti-valve seat recession additive like Valvemaster). Its formulation is designed to help cars operate at their best, using powerful cleaning agents and Friction Modification Technology (FMT). The cleaning agents are formulated to control the build-up of deposits in new cars and to assist in removing deposits in older cars. This can help restore performance. And FMT can help cars benefit from friction reduction.
