I’m pretty sure the anything above 93 is a waste. Double check the owners manual but I’m fairly certain the programming is optimized for 93.

The PCM can take advantage of higher octane, but not too much or not as much as a custom tune. So to the OP, no it won't be worse. It might make a bit more power and have more safety for hotter temps if you take it to the track.

IF your "93" octane gas is anything like what I have experienced, you could have some knock even with factory mapping. I would assume that running "100" would help guarantee that you will at least make what the engine is rated for. But again, that assumes "poor" quality 93. Only way to really know is datalogging and see if your seeing any knock. If your not, then it wouldn't be of any benefit I wouldn't think. Certainly as EFI stated, pending conditions it could provide some cushion to guarantee your getting what the factory programmed it for.

Pretty close. 98 Ron is equalivent to 93 Octane.

I run North American 93 octane and get better fuel mileage and power vs. lower octane.

As octane goes up the amount of fuel required goes up. I think e85 requires 30% MORE fueling, and thats 100 octane?

I get best mileage from ethanol free 93. I ran 93 shell for the summer as an experiment, 93 e/0 is superior IMO Assuming that its not chocolate milker bs fuel, to begin with

It's not the octane causing that its the ethanol content but yes as the ethanol content goes up mileage will go down.

That’s getting in the weeds of real gasoline, reformulated gas, gasohol, flex….. etc. etc.

Midwest pump available 93 nets my S550 5.0 more MPG. (BTU’s)
I have no idea what kind of at the pump fuel recipe is available in Ukraine
