Fuel grade required for the 2nd gen

[xxaarraa]

Hey *******, you sound like a 4 year old that yells "because science!" when he doesn't know what else to say.

I race 200 hp bikes that have race tunes on them and understand the basic principle of octane and what it does.

The discussion here is whether a Gen II Raptor in stock tune benefits from higher octane or not.

You did make me laugh, so points for that.

bro you really think you are going to come flip the script on the entire ******* planet saying higher octane is snake oil? seriously..... jesus you are one of the dumbest ones ive seen so far.

xxaarraa is from the City of Cheaters - what do you expect?

What kind of screen name is "xxaarraa" - oh, I see...

I applaud you for actually looking up the info in the manual.



Incorrect. First line clearly says it is designed to run on a minimum octane of 87. There is a BIG difference between "required" and "recommended" most of which is attributable to marketing (fanbois are eager to spend money on premium fuel because it sounds better than regular fuel, a truck that runs premium is better right? BMW has been doing this for years), and fine print to give Ford wiggle room in potential law suit defense down the line.

The manual also recommends a bunch of other stuff such as type of oil and air filter and disallows any mods, do you follow all of it like its the bible? Just curious.



There is definitely a debate on this. Instructors at Raptor Assault aren't running 93, you think they know a bit more about these trucks than Internet warriors on FRF? I think so. Look, I am not starting threads asking everyone to run 87. I choose to run 87 in my $71k truck because that feels better to me.

The Raptor runs fine on 87 because Ford idiot-proofed the design. They knew idiots like you would run cheap gas through the engine and they didn't want you to cry foul when detonation destroyed your internals.

The brilliance of the Raptor is the engine automatically retards the ignition to compensate for the retard sitting behind the wheel.

You feel the difference in octane on your bikes because those engines are not smart enough to compensate for the cheap fuel. You would feel the same problems with the Raptor if the engine wasn't smart enough to counteract your poor fueling decision.

that's a wrap

Damn son, you are a speshul kind of stupid

This shouldn't even be a discussion. Common sense tells you to run the best available fuel in a twin turbo, $60-70k+ truck. If you lack the common sense, use the advice of the manual.

I prefer to only run race fuel in mine. It's a real hassle to carry all the 55 gallon drums required for a long road trip but whatever is best for my truck!
(Lol jk)

But, even though I don't belong in the G2 group, in my 13 I ran 87 for a long time, it seemed to start ticking after 30 or 40k miles and I decided to try 2 tanks of premium and the small but noticably loud to me tick stopped. Then I tuned for 91 and it turned it into a new truck.


I have some understand of octane and why there are multiple levels and I'd say just driving around slow, yeah I'd run 87 on the ecobeast. But, not trying to start a war and this is all based on my experience and not facts, I would run 91 if you run harder, tow and really dig into the throttle.

I don't think ford has conspired with oil companies to try to steal more of your money I think that in their extended engine test their findings indicated that the engine ran smoother on 91 than 87.

Run what you want though! It's really up to the driver in the end!

I spent a good part of the afternoon working outside in the rain. It was quite depressing. However, coming in here and reading this thread has given me a stomach ache from laughing. A special thanks to all who have contributed to the question of octane levels, owners manuals and learning how to master the reading of the English language and what it represents. The photo of the infant at the keyboard just about put over the edge. With all the problems our brothers and sisters are going through in Texas and what is about to hit Florida over the next 72 hours, the question of octane levels and what to use for gas is really quite amusing. Stay thirsty my friends. Enjoy your trucks, life and family.

I posted this once before.

Just for the record:

from 2017 F150 Owner Manual:

Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87.

Some fuel stations, particularly those in high altitude areas, offer fuels posted as regular unleaded gasoline with an octane rating below 87. We do not recommend these fuels.

For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer. See Towing a Trailer.

Do not use any fuel other than those recommended because they could lead to engine damage that will not be covered by the vehicle Warranty. Note: Use of any fuel other than those recommended can impair the emission control system and cause a loss of vehicle performance.

Do not use:
Diesel fuel.
Fuels containing kerosene or paraffin.
Fuel containing more than 15% ethanol or E85 fuel.
Fuels containing methanol.
Fuels containing metallic-based additives, including manganese-based compounds.
Fuels containing the octane booster additive, methylcyclopentadienyl manganese tricarbonyl (MMT).
Leaded fuel (using leaded fuel is prohibited by law).

The use of fuels with metallic compounds such as methylcyclopentadienyl manganese tricarbonyl (commonly known as MMT), which is a manganese-based fuel additive, will impair engine performance and affect the emission control system.

Do not be concerned if the engine sometimes knocks lightly. However, if the engine knocks heavily while using fuel with the recommended octane rating, contact an authorized dealer to prevent any engine damage.

from Ford F150 Raptor Supplement Printing:

Required fuel: Minimum 87 octane.
