Yes works fine in fact smoother Idle and better response with a small bump in MPG.

 

I only use pure premium gas in my Scat. Works great! In fact that is all I used in my previous two challengers.

 

So either 91 or 93 ?

 

91 is suffice over that is just wallet drain.

 

Unless you've been specifically tuned to run 93 octane, otherwise 90 - 91 is just fine.

 

How do you even find ethanol-free gas? I'd love to give it a go, but not sure if there are any gas stations carrying it around here.

After moving to AR in Aug. 2020 my 2018 Hellcat got fed mostly 91 ethanol free. Then my 2020 Scat Pack. I wanted so much to experience a change for the better using ethanol free 91 but I didn't notice any.

91 ethanol free is about a nickle more expensive than 91 E10. However, the price difference is really no big deal.

You can certainly try 91 ethanol free gasoline in your car. If you notice any benefit well, at least you know.

I wanted to try 93 in the Hellcat and then the Scat Pack but never had a chance. Could not find any 93 around here and I never drove either car anyplace where 93 was available.

 

I’ll try 91 non ethanol when I get closer to E I just wanted to make sure I wouldn’t get a knock in the motor. Just being safe than sorry…

 

I get mine at Wawa except here they have it in 89 which works fine for me. My Friend with his 2010 R/T also uses it.

 

But 91 non ethanol is what I’m hearing that they have so I’ll go there after work to make sure

 

I use to run pure gas in mine but it's hard to find the 93 octane around here any more. They've all degraded on the octane for some reason.

 

I noticed a mileage gain as said. All 91 Premium is non ethanol here, 93 is almost impossible to find. We took the hit on regular, all is 10% ethanol. The big bonus is if a car sits, say months over the Winter with non ethanol. Off our fuel trucks, it is a 10 cents per liter spread over 87 regular. At the pumps, 16+ cents per liter here in Saskatchewan.

 

I personally don’t think ethanol in gas at 10% is all that bad as long as you burn it right away.

I had never heard of Buc-ee’s until about a week ago. We were driving home from a vacation last week and saw one for the first time, in Kentucky I think. That have a serious budget for billboards to, there must have been 50 of them.

 

Since November 20, 1942

 

Lol

 

93 E10 for the '21 and '87. Pure 91 for the '69.

 

Yeah I plan on sticking to 91 .. the only non ethanol I found at Wawa was 89 and Idk if that is safe to put in…

 

Been using it for my 2017 T/A
Plus, 5.7.
Runs good, never had an issue.
I store mine in the winter, no ethanol is a must for prolonged periods of none use.

 

Traveling through Tex. last week, I found different gas stations sold both 91 and 93. Filled up on 91 at one stop and 93 at the next. Never worried about it, didn't notice any difference. It was all good...
