But if you want insurance against engine damage, wouldnt it be a lot cheaper to actually get the Ford extended warranty for 125k miles (for around $1000-1200)?

Using 87 octane more than pays for the warranty in savings

Does the warranty give you more hp also?

I like how you used to argue there was no difference between the grades of fuel and now you're arguing the economics. Why does it bug you so much that some of us are willing to spend the extra coin to use the RECOMEMDED fuel grade for maximum performance? Are you a Saudi oil prince that only sells 87?

The mental gymnastics these guys will do to justify using shit fuel in a high performance engine is mind boggling, ain't it?

I'm actually arguing both. There is no realized different between the grades and I'm also arguing for the economics.

The gain in HP is likely only at high rpm and still is not enough for most to even notice. But by all means, if you are racing your truck then you should likely use it for that slight increase you may get. If I gave you 2 trucks to drive, 1 filled with 87 octane and 1 with 91 octane, you would not be able to tell me which is which.

I use 87 or if convenient to get, will pay more for 88 non-ethanol. (as that is actually better for the engine)

I could not care less what fuel you use, go use 106 octane racing fuel if you like. I can get that near me for $9.99/gal

But my point in my posts is for those who are looking for real information and not just "feelings". If you "feel" that 91 octane protects your engine (it doesnt) then go ahead and use it. If you "feel" it makes your truck faster in daily driving (it doesnt), then go for it!. Most people are like you and just make decisions on feelings, thats fine.

But some readers on here may prefer to use facts and reason. To each his own. I dont begrudge either.

I drove my previous vehicle to 250k mi so I'm not impressed with a near-term warranty. Seems like a no brainer to me to enjoy more performance today versus spending extra on a warranty and having to bring my truck into to be serviced because I was too cheap to put the right fuel it in.

You clearly do care. It's right there in the manual written by the manufacturer and we have dyno numbers to prove it. What do you have? "I don't hear any knock"?

Beyond the dyno numbers which is run on a flat surface with the AC off, we have real life situations where you can often find yourself in 100+ degree heat, AC blasting, going up a hill with several hundred lbs of passengers/cargo in the truck where detonation will occur at a far lower RPM than a simple dyno pull.

You want to be cheap, that's fine, it's your money and your truck. One day you may even convince yourself there's no difference. You'd (still) be wrong.

RPM is not important to octane, boost is where it makes a big difference.

Octane is a fuel's resistance to burning. High compression engines like forced induction run at much higher compression ratios and thus require higher octane. (higher compression generates more heat and is why the fuel needs a higher ignition temperature)

This has zero to do with the "quality" of fuel. 87 and 91 and 93 are of the same quality. Only difference is resistance to spontaneous combustion, meaning higher octane can handle higher compression before detonating.

The primary reason the Raptor engine puts out more power than the standard 3.5EB is our engines run higher boost and thus need higher octane.

But hey, it's your truck and you can use what ever kind of comicbook engineering you want to justify how you treat it.

Jabroni sir, ONCE AGAIN you have convinced me that the name you have chosen for yourself is perfect!


Below is copy/pasted straight from urban dictionary....I feel like you fit the last definition best.

This loser has Ford and dyno numbers supporting his position on fuel. What do you have, winner?

df, this is a lost cause brother.

Guys who honestly think they will drive their 5700 lb 10 speed trucks at over 4000 rpm (when redline is only 6k) all the time and need every last HP, will argue till the cows come home about the merits of 93. One knuckle head even compared the Raptor to a Ferrari! lol

Guys like you and me who live in the real world and are not magazine racers will probably run 87. The Raptor is not the most expensive vehicle I own, and I certainly won't be acting fresh about my "ferrari"

Just peace out.
