I've been seeing this at various stations in the last year and was tempted to try in my 2016 5.7 HEMI.

Most discussions about alternate ethanol fuels talk about lower mpg so I hadn't tried any.

Today I found this from an apparently solid source mnfuels.com or Minnesota:
"The energy density of Unleaded 88 or E88 and regular unleaded are very similar, and it’s unlikely you’ll notice any difference in fuel economy. In fact, one study conducted by the University of California showed some vehicles achieve slightly better miles per gallon with Unleaded 88 than regular unleaded."
And further," It’s good for your engine. Unleaded 88 burns cleaner and slower than regular unleaded, which has an octane rating of 87. The higher octane level helps boost horsepower and efficiency."

At the large savings per gallon, curious to know if others have tried E88. Seems worth a try.

Ummm no, I do believe your mistaken, E88 would be 88% Ethanol and 12% gas just like E85 is 85% Ethanol and 15% gas. BTW most of theses type of gas testing about how great Ethanol is, well what they do not tell ya is the fact they do not go out to the local gas station and buy the gas they will use for all those the test in their published report, what they do is they go buy fresh Ethanol direct from the refinery & the gas from a distributor that meets there requirements, they then mix the Ethanol & gas on site... People need to stop and ask why they will not go to the local gas station an buy the same ethanol blend gas that the every day public has to use to do all of there fancy testing? There is a reason they do not use same Ethanol blended gas the public has to use...

There's been several threads of people using E85 fuel with the same results, less fuel economy and power. Makes sense since the fuel has less energy per gallon than regular gasoline.
If I'm not mistaken neither the Hemi or Pentastar engine is suggested to run E85 fuel, only the older FlexFuel vehicles.

It’s good for your engine. Unleaded 88 burns cleaner and slower than regular unleaded, which has an octane rating of 87. The higher octane level helps boost horsepower and efficiency.
Who writes this bull excrement? What's so higher about 87 octane? It will only make more horsepower if the engine is tuned for high octane fuels. As for being "good for your engine", there's a few Dodge mechanics that will highly disagree with this statement.

To be clear, this thread is about E88. Not E85. E88 refers to 88 octane. An important question: has anyone tried it and what was the performance and mpg?

For what it's worth, Fueleconomy.gov, which is run by U.S. Department of Energy, says unleaded 88/E15 will get 3% to 4% less miles per gallon than regular unleaded 87 gasoline.

(That seems similar to what other posters have found on E85.)

And there's this, "tests done in California show that newer vehicles were only 1.3% less efficient when using unleaded 88 rather than unleaded 87. The test looked at 20 newer vehicles and included everything from a 2018 Honda Civic to a 2018 Chevy Suburban."

"Underwriters Laboratories announced its research supports the use of fuel blends containing 15% ethanol."

So what matters most is what Ram E88 users have experienced.

the compression ratio of your engine determines the octane rating for the gas you should use for your truck. The higher the compression ration of your vehicle, the higher the horsepower. This is why high-performance engines require more octane.
If you have the HEMI V8 engine, you should use the 89 octane, if you have the base V6 engine, then it is okay to use the 87. Just never use higher than 89!

. Mid grade is recommended. Premium is a waste of money. This assumes it is a Hemi. If it’s a V6, anything other than regular is a waste of money.

They say 87 acceptable, 89 recommended and DO NOT USE E85.,
If i remember correctly, in your Owner Manual, it reads
that you could use 10% ethanol.
It never reads that you could use 15% ethanol

Like I would believe anything that is stated as fact coming out of CA (the guys that want to ban ICE's).

Just look at the BTU/g rating of the gasoline vs ethenol. BTU's (or the energy rating) are what is needed to create heat / energy. Gas is 125,000 BTU/g and ethenol 84,530 BTU/g. The math is pretty simple and VERY obvious

There has never been a religious conflict in human history as passionate or irreconcilable or dogmatic as the uh "debate" about ethanol. Nobody will ever under any circumstances learn anything or change their mind about anything in a hundred billion of these threads regardless of any evidence or documentation provided.

It’s not E88, it’s UNLEADED 88 or E15 as per the Minnesota Fuels article you referenced. E88 would be an 88% ethanol fuel. Most gasoline sold in the US and Canada contains up to 10% ethanol making it E10. Ethanol is an alcohol and just like when we humans drink alcohol it dehydrates. On old vehicles with rubber seals the ethanol dries out the seals. Fuel with ethanol that sits for extended periods absorbs water and gets “gummy”. Outdoor power equipment is prone to ethanol fuel clogging up the small carburetors. Don’t take my word for it, Google it. As for your references, fuel economy dot gov takes me to their home page not any specific article and the California testing results takes me to a “tweet” by Robert White who is the president of the Renewable Fuels Association. MNFuels and the RFA are in business to sell bio fuels so of course they will espouse all the benefits of ethanol mixed fuels. Your Bio says you have a 2016 truck, have you checked the owners manual to find out if your vehicle can use E15? I own a flex fuel Pentastar V6 and I’ve tried E15 and E85. I have no long term usage data as I only find E85 available in Pennsylvania when visiting my sister. The few times I’ve used it mpg was poor but the motor “felt” peppier which is subjective at best. E15 fuel I’ve used on long highway trips and I’ve been pleased with the mpg versus price compared with regular 87 octane. Mpg’s were the same as per the dashboard mpg readout. Again no long term data as these fuels are not available in my home area.

I expect the differences between 87/E10, 88/E15, and 89/E10 are so slight as to be imperceptible to most drivers. I’ve run all 3 at various times in the Wagon -and the occasion 91 or 93- and whatever changes in performance exist are overshadowed by other variables like elevation change, traffic, wind direction… you get the idea.

No doubt, on an instrumented test vehicle with a repeatable drive cycle, differences could be measured. Or at the drag strip. That’s not the real world I drive in, though.

For an imperceptible difference, I’d damn sure buy it for $.70 less.

In the markets I’ve seen it, octane seems to be the price driver and it’s not cheaper than 87.
