Thanx for the info actually all i wanted to know does higher octane damage engine or not . one more thing, by going to owner's manual again found that the note of Premium fuel that was for the Eco-Boost engines, but the engine i have is non Eco-Boost engine. so i think it is clear now. :D

i just got ford explorer 2013 xlt (3.5L v6) non Eco-Boost in the owner's manual they are saying: " 3.5L V6 engine: Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. 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. " does this mean if I use fuel with octane 93 (or higher) will be better ? or at least it will not damage my car ??
