I use 87 which is the reg here in MN where I am. Whenever I use the mid when its the same price I get less mpgs. I have never calculated it but I can tell the miles to a tank go down with the same style of driving so I stick with 87

Run 87. Your wallet will like you better.

Running an octane higher than the manufacturer suggests will not do anything for your performance or mileage. It will not hinder it either, it's just a waste of money. More modern engines using an extremely high compression or turbo/superchargers will require higher octane for it's anti-knock properties. Even in these vehicles you probably won't notice much difference when running lower octane because the computer will compensate by retarding the ignition timing. This will have an adverse affect on mileage and performance but because the engines nowadays are so well at compensating, they will seem to run perfectly normal.
As far as I know, this generations F-150's do not require anything above 87 octane. I wouldn't waste my time going higher than that.

Nothing lower than 87 here. Although I have seen 85 in Utah.

Do what you want. Apparently FORD engineers don't know squat about recommended fuel.

I bet if you guys who think running a higher octane makes a difference have someone else fill up your tank a few times and make u guess what octane was used you couldn't tell the difference. It's just a psychological placebo effect.
For those who calculated their mpg's and found that higher octane results in higher mpg, multiple things affect mpg such as driving conditions, driving style, temperature, etc. not just octane level. Also, people tend to drive differently if they're trying something new on they're vehicle. These people could have gotten better mpg's using a higher octane since they were not ******* the truck as much as they normally would. Use what the factory recommends, those specs. are there for a reason. Only reason not to listen to them would be if a tuner was used or other outside modifications, if the trucks stock follow the recommended specs.

I don't know if this applies to big v8s but I know guys that ran 50/50 race gas in lightly modded sleds(like just exhaust) and it ran like **** compared to just premium. I always use regular in my truck
