You will notice a bump in power stock but unless you're running a 93 performance tune, it won't make a big difference.
You can also run E85 with the same results. It's supposedly 105 octane iirc but varies based on what I've read.

The 100 octane racing gas is likely aviation gas, which is 100LL. The LL means low lead, so I'm assuming it still has some lead in it. Whether it's enough to harm a catalytic converter, I don't know.

they have 110 leaded Racing Gas and 100 Unleaded... It's damm expensive 7.5 a gallon for 100 octane regular (unleaded) I didn't even look at the 110. Still pretty cool. I'm going to give E85 a try and see what my MPG's work out to be, Right now I get approx 14 ave highway and city. It really couldn't get worse.

It will get lower mileage on E85 since it has less energy per gal compared to gasoline. The truck runs good on it with a 5 Star 93 performance tune, but it is definitely thirsty especially if you have some fun driving it. I ended up around 11.5 running it for two tanks.
E85 is about .20/gal cheaper than 87 here. I've also seen a couple of Sunoco stations with race gas, never really paid much attention to the price but it wouldn't surprise me if it was $7.50 a gallon.

I have the 2012 SD. It'll run flex Fuel. Your 150 has the same motor as mine. Like Saratoga 2011 said it'll make the 6.2 thirsty. So now I'm thinking I'll just stick to Regular. Cheaper Gas that gets me less mileage so I have to fill up more? That's not very smart. Even if it's made with American Corn. Unless I can't afford regular. I'm sticking to it.

I realize the motor is capable of burning e85, but is the fuel delivery and tune the same in the f150? From the tank to the injectors to the computer, it all needs to know e85 is in the tank.
I only ask (and then ask again) because everything else I'm reading is saying no.
And not to discredit Saratoga but what he is saying doesn't make any sense at all to me.
Why would a 93 octane tune be optimal for 100+ octane? How is he getting 11mpg on e85 where most of use see 12-13 on 93oct? I'd expect to see 9ish at best.
I used to fill up twice a week, with a 36gal tank I fill up every 8 days. If I'm making more power and filling up 30% more often, I'm good with that.

If the vehicle says "flex fuel" on it that's Ford's way of indicating that the entire fuel delivery system is rated for E-85. The Super Duties are flex fuel, I don't know if I've noticed the plate on a Raptor so I can't speak for the F-150's.
What's odd is that normal gas-engined Fusions are "flex fuel" rated, but the Fusion Hybrid is not. My suspicion has always been that using E-85 gives a poorer MPG result and they don't want bad numbers in their flagship hybrid vehicle.

Powellgator I think we are on the same page... But I also think the f150s with the 6.2 are "too flashy" from Ford to clutter them with RELEVANT badging.
I'll check my gas cap today to see if there is anything on it.
Thanks for the insight guys.

I think this says it all.

Note the 3.7 and the 5.0 are rated for E85 where the EB and 6.2 are not.
