Fuel Quality
1.6L and 2.0L EcoBoost® engines
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as "Regular" with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage.
Ford原始設計是覺得92就夠了，如果有特殊的拖拉需求才需要用更高辛烷值。基本上美國一般家庭用車的設計都不會採用需要高辛烷值的設計。當然，如果真的很在乎用油影響的人是可以採用高一級的燃油，但原廠的態度很清楚就只是經濟性跟性能上的取捨罷了..
為了省那兩塊或油耗.引擎態速應該會粗糙點
別到後來搞的換火星塞燃燒不完全
或油路噴油嘴.再加清積碳這些錢就回來了!
火星塞有冷熱值.電腦設定不同油也會影響
加98，偶爾有爆震是正常
是讓他頭好壯壯不容易積碳
換成我偶爾加加98讓車引順暢點...
那真如此原廠手冊應該會建議用92?
況且台灣KUGA車是全美規車嗎?
