Unless you have a tuner designed for a higher octane..

 

Octane boosters would cost way more to get the same octane out of a full tank of fuel than it would to just buy the premium fuel. Have you ever read the back of a bottle of that stuff? For example, says on the front of Prestone's 0-60 booster, "raises octane 10 points!" Ok then you flip it over and read the fine print.....one point is .1 of an octane number. So in effect you would need 60 "points" to go from 87 to 93, which is 6 bottles of this stuff!!! Not to mention the fact that the 35.7 gallon tank I have will probably take about 1.5X the dosage to get the same results. I usually fill up at Sheets and spend about $3 more per TANK to fill with 93 as opposed to 87 octane. So which is better $3 at the pump or 9 bottles of octane booster every tank.........

 

Makes a lot of sense. Thank you.

 

The feeling of your truck running better with higher octane is because of your computer is adding timing which is what higher octane does. All of our engines run different so Octane would mostly depend on where you live. I run 87 and experience little to 0 knock retard with it. The best way to know if your running the right octane is to have your truck scanned.

 

Scanned? What do you mean by scanned?

 

You get your best fuel economy and make the most hp by using the octane rating the truck is tuned for. Stock F150’s are tuned for 87-octane therefore more octane will actually reduce power and fuel mileage.

93-octane fuel takes longer to ignite than 87-octane but once lit they burn at the same speed.

Heptane is a volatile, colorless, highly flammable liquid hydrocarbon, C7H16, obtained in the fractional distillation of petroleum and used as a standard in determining octane ratings. (R+M/2) 87-octane fuel is 13% heptane and 87% octane. The more heptane the quicker the fuel ignites.

 

I'm running 93 octane here 'cause I got the SuperChips 1714 high performance tune loaded.
