Does anyone run ethanol free gas in lieu of premium in their 6.2 engine

Has anyone tried EF gas. I tried it in the 5.3 for the first time the other day. My highest mpg was 26 mpg Highway. My avg was 25 mpg on the highway
my non highway mpg was 18-19 mpg

In FL it’s about + .80-.90 a gal here Over RUL. I hardly ever see anyone reach for that handle. I purposely by it for my outdoor power equipment and jerry cans as it stores much longer and doesn’t foul carburetors and injectors as easily….

^^^ similar situation. It's about $0.30-0.40 higher here, and is available only in 87 octane (our mid-grade at this altitude). I do run it occasionally in my DD but always in the power equipment. Never in the Hoe, typically run E85 in the summer when I can get it and 91 octane in the winter.

Ethanol or not, if you have the 6.2 91 min is recommended in ‘22, 93 octane in ‘21. The point of the high octane is to prevent pre-detonation, where the air fuel mix heats to the point of ignition before the optimal ignition point (when the ecu fires the spark plug). This is commonly known as “engine knock.” Whether it’s pure gas, e-10, e-15, there is a min octane rating…and it relates to the resistance to pre-detonation…do your 6.2 a favor and use the recommended octane.

Here in iowa it’s hard to find ethanol free gasoline that’s reasonably priced. You’d probably get 5-10% better fuel economy without 10% ethanol and with 15% ethanol up to 5% worse gas mileage compared to E10 (which I’ve kinda confirmed here lately as I’ve been doing some experimentation).

For me to make the jump to the 15% ethanol my rule of thumb is to use that if it’s 20-30 cents less than the E10 which here is usually more expansive.

Here in my area though E10 is the typical stuff. Going from E10 to no ethanol is about a 0.80-1.30 higher cost per gallon to fill up which is usually the premium grade stuff. For me I wouldn’t make up the difference by paying the higher cost per gallon.

here in pa. Ethanol Free is rated at 89 octane and is .50 cents more than unl reg and .40 cents cheaper than premium. I had never seen it offered before. This station just opened up

Sigh. If we could only get people to drop the decimal point when they use the word "cents." Unless, of course, they mean some fraction of a cent. 40 cents = $0.40.

Is that your .02 cents?

Of course. Penny for your thoughts....

Also reminds me of those attempting to use a shortcut for the model year. '21 turns into 21' (21 feet).

What did you pay per gallon for it vs the price of regular gas
