Tested: Is Higher Octane Fuel Better? Better MPG? More HP? -- 87 vs 91 vs 93 Octane with Ethanol Edition (by Project Farm)

Well he did go to great lengths to prove it doesn't matter in small carbureted engines.

For those who don't want to watch a 10 minute fast talking video, here is the cliff notes.

Consider this your zero to 60 times under high load.

(not in a Maverick but you get the idea)

If hundredths of a second matter to you, by all means, give the gas companies hundreds of more dollars.

It gave me a headache…

Thats the fumes from the high octane gas you are using.

Okay, so buy the highest octane gas I can find. Got it.

I'm pretty sure you didn't watch the video. It clearly states to use Sunoco Green E15.

Racing fuel? Perfect!

Yep, I watched his video the other day and if you stick with it to the end he recommends a higher octane fuel for turbo engines.

I liked the video and what he says tracks with the manual, both suggest to use higher octane with higher engine demand actions (turbos, towing,)

Project Farm finally created video and confirms in his test that there is no reason to pay extra 10% for the pure Gas.

I'm having trouble with his odd methods of testing fuel and how that relates back to driving a real truck.

I have mentioned it in other threads, but I've owned multiple factory turbo vehicles in the past 16 years and been on many forums. I have not seen a single time someone has run regular (87) octane fuel and not had major issues around 150k. I know most people trade their vehicles before the warranty, but for those of us in for the long haul, you cannot go wrong with quality in the long run. Also, as a side note, I regularly tow and haul with mone. I got it from a dealer 4/5(ish)/2022 I will be out of warranty in the next 2 months.

It's a 3 year 36K warranty, have you almost hit 36K on it? I think the drivetrain is covered farther than 36K. I picked mine up 11/18/22. To date it has 7600 miles on it. I just use it for back and forth to work.

This thread is dumb. The original premise of the video has very little correlation to our motors. This topic has been beaten to death and like our current politics you either fall into one of two camps and there is no convincing the other side despite what thermodynamics says.

The benefit of higher octane is preventing knock in a high compression engine, granted the engine will adjust but not until knock is detected, if a knock happens it has already caused some damage.

This, high octane is not for fuel economy it’s for the safety and longevity of the engine. People don’t understand this I’d rather pay the extra for peace of mind my engine isn’t knocking itself to death

Nobody's EB is going to knock using 87 octane fuel, it just won't. Nor is your vehicle adjusting to and stopping a knock from occurring.

But pay your extra $0.40/gal

Ridiculous. 91 is $0.40/gal or more than 87. At an average of 30 mpg (hardly anyone is actually achieving this in an EB) you're paying at least $1,500 per 100k driven. At least.

Just give me a new EB at 100k.

87 doesn't make an engine knock itself to death. 91 just makes you overpay.

I'm sitting at 31k right now. I am guessing 2-3 months I will be at 36k. I also installed a 2" lift a few months ago, so most of the drivetrain will not be covered under warranty.
