It pains me to say this ...

By the by, I didn't mean to start a Premium vs Regular thread, since I think that's been beaten to death. lol. I was just baring my soul and admitting that I can feel a difference - small thought it is - between brands of gas, when I've stated before that it's all the same.

Honestly this is probably the best fuel thread I've read so far. I liked your opinion based statement instead of stating a "fact"/I'm right your wrong(since yeah it has been beaten to death.

Maybe this is like one side of the mountain versus the other. For instance, I feel a big difference in performance while going downhill vs uphill. Same mountain, though, so it might be bias... lol

Good discussion here but guys you need to refer to the octane versus terms like "regular" or "premium" because it differs in every area. Regular in my area is 89 octane and so called "premium" is still only 91 octane.

Yes and no - regular in Australia is 91 octane and then we have e10 with 93-94 octane, premium with 95 octane, super premium with 98 octane, and a few places offer a 100 octane fuel (using ethanol to boost the octane rating) as well. We have E85 (which varies from E70 to E85, depending on time of year) as well, just to throw you out, not sure where the octane rating is on that. Europe is different again, I am sure that Korea has variations too.

And yes, our octane rating numbers are higher for the same actual fuel quality than in North America, because we use a different scale (RON, same as Europe, you guys use PON, which is an average of MON and RON).

And if you're from North America, stop complaining about your fuel prices. We pay between $1.50 And $1.99 per LITRE (not gallon) for our Super Premium. And Europe is worse again I believe.

Yes, the stop complaining bit is tongue in cheek. You lucky buggers.

on the 2018 Stinger, I've had the opportunity to use "pure" gas a few times and I can say the performance with that at 93 octane is better than using Shell top blend with detergent and ethanol. Doing a complete fill I've found the car more responsive and have seen 383 miles to the tank with about 10 listed before empty. Trouble is, I have to drive 50 miles to get that, which is in the area I bought the 2018, so I haven't fed the 2019 none of that yet.

Yes, but can you PROVE that your car performs better going downhill? Charts and graphs, buster!

(Just kidding. )

Don't make provocative posts and you won't be judged!

I doubt your "findings". The "bump" could be instantaneous response from a sporty drivetrain. Whereas crud for gas is "smooth" because it is not allowing that instantaneous response. Then again, it could all be coincidental to transmission operation.

Top Tier gasolines got that way for a reason. It doesn't make sense to go with a cheaper grade gasoline just because of a "bump". What kind of acceleration difference is there? If the cheaper gas seems smoother but flatter, then I'd go with the "bump" gas. And then again, any differences might only show up over extended running time as a cleaner or dirtier engine. Etc.

For a while, with a certain tune, I swore my '05 LGT ran better with 76 than Shell or other premium gas. It seemed smoother at partial throttle. But, with the later tune, and a fixed coil, that problem went away.. So I understand what you're saying, but in my case, I'm thinking it was all in my head..

This rates as the oddest "introductory post" I've seen yet. Welcome anyway, @midwest Stinger.

@midwest Stinger - welcome and where are you located?
