Fux with the best, Die like the rest
I don't get what you're implying but ok. I gave you the correct answer but you kinda balked about price still. That's why my second comment about ammo. You wouldn't use it to save money. Don't do the same with an engine. In reality a bike gets 40mpg and has a couple of gallon gas tank. It's less than a dollar a tank.
I run 93 in a boat buring 7.5 gallons an hour for protection against detonation. Please treat your toys nice.
They’re out there, just not very common at all. Mine, in my year, color, and options, is one of 279 in existence

Yeah they lower the octane at elevation…it’s a relic from the old days of carbs and less-sophisticated fuel injection.
For modern vehicles, it’s actually not great to lower the octane at elevation, because it’s working against the high-altitude adjustments that the ECU is making.

Yes.
From the manual:
98 ROZ/RON, Premium plus unleaded
95 ROZ/RON, Premium unleaded (fuel grade, usable with power and consumption related restrictions)
From a bike review:
Fuel grade: Premium plus, unleaded, 98 RON
Use of premium down to 95 RON possible thanks to automatic knock control
I've spent a fair amount of time researching octane-to-RON conversion but there doesn't seem to be a hard & fast rule. One result showed 89=95 RON but the others were below.
Just because you can, doesn't mean you should.
I would look at what the manual says as, if you are unable to find premium, you can use regular.
But, not all the time.
Also, as summer comes, it's even worse.

95 RON is supposed to be equivalent to 91 AKI, which is what "premium" usually is in other states. We're lucky we have 93 here.Yes.

Based on what the manual is saying it sounds like 93 is recommended, and 91 is the minimum it can adjust for.
You could write a book on this subject and still not be 100% accurate with a recommendation. There's a LOT of variability - air pressure / altitude / absolute pressure, intake air temperature, cylinder head temperature, relative humidity, manifold pressure, static compression ratio, RPM, engine load, cam timing, dynamic compression ratio, fuel blend (including ethanol content), blah blah blah. It's all related, and it all boils down to kind of a fuzzy range of acceptable fuels for the expected operating conditions.
In general, the hotter the motor, the hotter the air, and the higher the load the higher the chances are for the fuel to detonate. Many modern engines have a lot of tools to combat detonation to avoid damaging the motor (knock sensors, spark current measurement, electronic ignition, variable valve timing, throttle by wire, etc.) so you can run low octane fuel without breaking anything. You'll just experience lower power if the ECU determines there's knock and compensates.
The higher the octane rating, the slower the fuel burns, which can have the effect of reducing power and efficiency in a motor that can't take advantage of it. So putting premium in your Camry is just wasting money. On the flip side, you can potentially make more power with a higher octane fuel in a motor that would otherwise knock on lower octane fuels. As a side note, ethanol tends to dramatically increase the 'effective' octane rating, as it will cool and slow the flame front. Problem here is you rarely know the percentage and can't rely on it.

OK, that one's for fun but for serious times, a Stebel can be had for <$40. I have a single on my bike and it DEF gets peoples attention. I was behind a woman in a car legitimately waiting for traffic to exit a parking lot to the street. A huge gap with no movement and I realized she was putzing around on her phone so I sounded the horn. She threw it into the ceiling and it bounced to the rear seat, then she drove away.

I was thinking that too Brains, I just couldn't find the words.
Thanks for the input. At the risk of pissing off others since I do it so well, I consider you two the auto go to guys here on TGT.
I'm looking for a different kind of attention. It's a 1927 Buick so that's what it needs.
