high octane gas or low octane gas

[DAMIEN1307]

I can't get ethanol free. I need to go find some and get a gallon or two of it.

Just click on this and scroll down to Nyssa...You will find there is a couple of listings for places reported to be carrying Ethanol-Free Gasoline.

The Owyhee store is way out of town, and when i checked the COOP they said they didn't have any. I'll check there again soon.

Let me clear this up. I can't take it. High octane gas burns at the same rate. It is just able to resist ignition more than a lower octane. Think of it like this. Low octane can be set off like a liberal. It's easy to get burning down a city. High octane takes more pressure ( heat ) to crack the molecule to release it's energy. High octane is like a Queens guard, takes a bit to get them to set off, but they will fire off and burn you down just as fast a liberal.

‘Set off like a liberal…’ Nice writing.

As I said, the term slower burning is still somewhat accurate if comparing the two fuels under the same conditions. it's just a laymans term for the average person to understand. To those of us that understand the difference, yes, it's not technically accurate.

You don't need to explain it to me, figured that was obvious from my last post, so you can lay off the encyclopedia explainica.

‘Encyclopedia explainica.’ Awesome phrase that I haven’t heard. Permission to utilize?

"Remember at 6k rpms, the engine is firing 6000 times a minute( 60 times a second"

6000 rpm/60 seconds per minute = 100 rps.. Just sayin

Or 1 revolution every .01 seconds, and if the ignition timing is say 20 degrees BTDC and he exhaust port opens at say 95 degrees ATDC - or 115 degrees of rotation for charge ignition/burn - the fuel has .0031944 seconds to ignite and burn. Anything after that basically produces no power, and the rest of it goes out the exhaust. Suddenly burn speed matters a bit more when you look at it in that context. Plus, the higher the RPM, the less time it has to burn. At 12,000 rpm it's a paltry .0015972 seconds

I always loved these types of videos, and I always think of them when these conversations come up.

While you guys are debating octane ratings, I'm filling my ride up with 85 reg and enjoying the ride. Here in the Rockies we 85/87/89 choices.
