Is it worth it to put premium gas into your car? And what’s even the difference between the regular and premium gas? It all has to do with the octane rating, which we’ll explain with fire, ice-cream, and a bit of chemistry trivia. 00:00 - Intro 01:18 - What Does Octane Measure? 01:29 - How Combustion Works in a Gasoline Engine 02:13 - How Compression Leads to Self-Ignition 03:00 - Engine Knock 03:31 - How is Gasoline Produced? 04:11 - How is the Octane Rating Measured? 05:29 - Why They Used to Put Lead in Gas 07:07 - Which Gas Should I Use? #octane #engine #premiumgas You might also like: Fuel Cell Cars: The Future or Gas Guzzlers in Disguise?: 🤍youtu.be/R6AdX-bdDaw Chemtrails: 🤍youtu.be/ZonPvpgcBc0 How Oxygen Masks Brought Down a Plane: 🤍youtu.be/KejaV70RWPk I Created an Oil Spill in My House: 🤍youtu.be/n2761go6OYg Credits: Executive Producers: Hilary Hudson Producers: Elaine Seward Andrew Sobey Darren Weaver Writer/Host: Alex Dainis, PhD Scientific consultants: Michelle Boucher, PhD John Heywood, PhD Brianne Raccor, PhD Sources: Here's What 'Compression Ratio' Actually Means And Why It Matters 🤍jalopnik.com/heres-what-compression-ratio-actually-means-and-why-it-1819723873 Here's How Your Car's Engine Works 🤍🤍caranddriver.com/features/a26962316/how-a-car-works/ Benefits of a Diesel Engine 🤍kiowacountypress.net/content/benefits-diesel-engine#:~:text=Diesel%20engines%20have%20fewer%20moving,to%20be%20changed%20or%20repaired Why No Diesel Cars in the U.S.?

Not really "built to handle", really more "built to need it".

IME, cars built for regular get poorer mileage on premium than on regular. Unclear if mileage is a good proxy for "more energy", but that's the number I have to work with.

I don't use ethanol blend ever. Regular 87 or 91 premium fuel only. I know there's a difference, anything without ethanol

R+M/2, just a 'sales dept' way to increase the M (Motor Method) number, which is the one that really counts. The cognoscenti know why they don't use the M number, because it doesn't sound as impressive. The R (Research Number) number, is not relevant at all, since if the fuel is sufficient to prevent detonation at higher cylinder pressures (large throttle plate openings), it is bound to prevent it at the lower pressures that the R rating is supposed to address.

the way it was explained to me in high school.
the octane rating denotes when and where combustion occurs in the piston shaft. the higher the octane rating, the higher up the shaft is where combustion occurs. This creates a harder drive, and thus more horse power.

Why don't they have a tank of 87 octane and a tank of octane booster, and then any octane rating can be dialled in?

Just today I saw Alex's 'matchstick chemistry video' which she uploaded 8 years ago and now YouTube recommended me this video. The YouTube algorithm at its finest!

So what about 85 octane?

So really it's Non-leaded fuel, not unleaded fuel.
