For regular highway driving, in my testing, Regular gas gives you the best mileage. V8s are really forgiving in what you put in them. If you need to race somebody, then that's another story.

You are right and it's truly a shame. I used to visit your city several times a year "back in the day" and actually looked forward to it. Night time, it was safe there and I truly enjoyed the place, staying in The Drake Hotel and eating downstairs there and other fine places. I hear the Drake is managed by Hilton now. Don't know if that's good or not. It isn't owned by Hilton, which is good.

Today, no way I would go where I went or do what I did there. A lot of business used to go on there that doesn't today. Pritzger is clueless and is part of "the elite". They ruin too much of the country.
They should all have to be in debt to own houses, cars, and go on vacations.
Yeah, it was a great place years back.
I used to brag about being from Chicago, grew up a city boy.
Now in the burbs and only go for work. It’s not the same.
Sorry about my rant… no more politics back to Mustangs

2019 Ram Rebel, 2025 GT Premium with PP, Active Exhaust, 401A, Magnaride.
Reached the 500 some miles mark and today 3 hours on the highway has me at 22 MPG now.
87 degree weather and Engine Temp was around 189-192, transmission under 200 too.
Loving this car.

A little off topic but back in the 90's I had a team of technicians working for me and they regularly drove 1k-2k miles a week servicing clients.
The majority drove Volvo's which at the time literally lasted forever. However there was one major difference between the ~10 techs and it was always a point of discussion over cafe. The topic was the top tier gas vs the cheapest gas, no matter the grade. At some point it became obvious that assuming regular PM was done, the cars using the cheaper gas had more problems than those using the top tier brands. From that point on, I have always used top tier gas and I've never had any fuel related issues on my cars other than the normal sick fuel pump now and then.
Completely unscientific but food for thought.

Almost like it was designed to run on 87... imagine that!

My take on it is that, while you need 91 or higher to realize the full potential of the engine, running it on 87 does not harm the engine as long as you aren't hearing any knocking.

My GT is my DD when I'm not on the bike. Roughly 60 miles round-trip to and from work. I fill up with 87, and have had zero issues in the last year and 11,000 miles.
You think this is bad, ask about oil...
Or fender holes :DDDDD

Interesting considering that Top Tier gas didn't come out until 2004 so it wasn't around in the 90's

It was and has been in Europe for years, even with leaded petrol. We had 2 star (90 RON) up to 5 star (101 RON) from the 1960's onwards - prior to that it was a bit vague. After lead was removed we had Premium (95 RON) and Super (97 to 99 RON)

I don't think we are talking about the same thing

True however by top tier I meant brands like Exxon, Mobil, Sunoco vs the off brands . Poor choice of terms on my part. And the second part of the conversation would usually revolve around "but it all comes from the same place" topic. Lot's of urban legends in that discussion.

Get the gas buddy app if you must. Personally I would never, not sure if it damages the engine or not but I would want my 5.0 to operate at optimal performance.

Also, consider getting a daily if you can.

On thing I do in my car is put ethanol free gas 90 octane, better miles per gallon, slight improvement in acceleration. I have done this by resetting trip counter and full tank...sometimes that gas is also cheaper than higher octane fuel like 91 & 93. I have 30000 miles on the car with zero issues. This improves even more on the highway. I have gt performance pack with active exhaust.
