    Manual says 87 octane recommended.

    Anyone have an opinion on this? I was planning on always using 93 for out turbocharged engine until I read my manual this morning. Bought the 2014 ST yesterday and haven't needed fuel yet. Opinions on this?


    ....I love my ST

    It CAN run on 87 but it makes about 7 more HP on 91/92/93 fuel (I dont remember) They only sell up to 92 around my area so thats what I put in. Some people also report higher MPG on the premium fuel but i'm not sure if thats true or not. My opinion is just fill er up with the 93 if you can

    I fill up with 87 no problem. It's not like 93 is a magical fuel that makes your car happier. Most of my driving is commuting 40 miles to and from work each day, and thus have no use for the additional horsepower 93 provides. I do fill up with 93 though if I am taking it to the track or to an autocross. Other than that, all 87 for me and the car feels great.

    Basically agree with what these guys are saying. 87 is fine for commuting and whatnot but if you want to race it and get the best performance than premium (91/93) is the way to go.

    I believe the horsepower stays the same, the torque is reduced due to less timing to compensate for the lower Octane fuel.

    I always use 93 in mine. The extra 2 or 3 bucks it costs for the difference isn't gonna make or break the budget.

    Besides I paid for all of the horsepower I might as well use it all.

    I've bought nothing but 87, primary use is daily driving. Plenty of power when I want it and 30 mpg. My trip consists primarily of highway, with some traffic lights and an occasional traffic jam. If I was going to track or so go attack the Dragon/Tail of the Dragon I've fill up with 93 as suggested in the manual.
    Going old is unavoidable ... growing up is optional.

    Whatever you use, don't overfill, and probably don't top off.

    It's 243 hp/270 lb-ft of torque on 87 octane vs 252 hp/270 lb-ft of torque on 93 octane. The torque target is unchanged, however on 93 octane the car makes 9 more horsepower according to the owners guide supplement and every other published piece of information from Ford.

    Yea because it is part of the "world car" or whatever ford calls it the ECU can handle a large range of fuels. You can use 87 up to 93. In high temperature summer days or hard driving 93 would be better. The real question is if MPG gets affected under normal driving with the lower octane.
