I have heard both stories putting higher octane in a car/truck gives you better gas mileage and horsepower and also that you get worse mpg and harms engine putting in higher octane than what is recommended by manufacturer. Which one is true?

I find no difference unless I buy gas without 10 ethanol.

lowest octane rating where the engine still runs smooth. higher octane rating does not save fuel. even if it did it would not make up the difference in the higher cost of the fuel.

higher octane is fed to my 2 classic cars w/ high compression motors, to avoid spark knock (pinging), not for economy

"it's a myth"

.....

Exactly...debunked years ago the myth seems to live on as there's sufficient enough gullible lamebrains willing to blow their money on about anything anyone tells them to keep the myth alive and well.

As the old saying goes: "Sometimes you just can't fix stupid".

Even if it was true the higher cost offsets any savings.

I use higher octane than required to avoid ethanol in fuel. I then later had my ecm reprogrammed for higher octane though...

Higher octane fuels deliver less fuel economy. I tried 87 to 92 in my KIA sorento and got 1.3 mpg less.[this was done over a 7 day test]

Higher octane gas positively does not save fuel and will damage your intakes with prolonged use of it.

No, I'm using regular. How much gas can you save with Premium gas? You wouldn't save more than you paid for Premium gas.
