@@camfocus8888 “Diesel fuel has an octane rating of 25-40. Mixing 2% diesel fuel into gasoline will lower the overall octane rating by 1 point. Getting 10% diesel contamination lowers octane by 5 points, which is enough to create problems in most engines. The octane depression rises linearly with increasing percentages of diesel fuel in the gasoline.” 降低喔…..原廠建議95/98的汽油,加95也有可能比98比較不會積碳,但是爆震機率提高而已。
