I got less than 10 on 89 octane and 11 with 93 octane. I've never towed with 87 octane, but run it all winter. I do run the Livernois tow tunes - 87 tune with 93 octane yielded about 10 mpg, 89 tune with 89 octane was 9.5-10 with 89 octane and 11mpg with 93 octane. This summer I will run the 91 tow tune with 91/93 gas. I am towing a fifth wheel which has better aero. All towing is at 60mph on the interstates.

They did it with the N/A 3.7 Mustang AND the 5.0.

Ford's timing tables from 2011+ vehicles on are EXTREMELY aggressive. The engine management will increase timing until it senses knock, and then pull back. Then keep on doing it until the most hp is achieved (along with other variables).

I see no reason why this isn't at least plausible if not true on the F150's as well.

Plausible yes. Do you have the graphs or link for the tests done on the mustang?

People actually put regular octane in thier EB? Always thought that this engine required premium fuel, as with all other turbo engines usually do. That just the way it always been for me; if it has a turbo or s/c, it needs premium/ higher grade fuel.

Nope. The Eco is built to run on 87. It just runs a bit faster on 91 :-)

It's not plausible for the 3.7's. It's a fact. 93 octane in the Mustang motors, both 5.0 and 3.7 will net you more power.

I have no doubt it's the same for the trucks.

I know that 5.0 Mustang talk is a bit off topic here but one of the major Mustang tuners did a dyno run of a 5.0 on 87 octane, drained the tank and then ran a 93 octane dyno run. The 93 octane gave it a 10 horsepower increase.

I thought I read 377HP and 390 TQ with E85 in the 5.0l
