Interesting. Seems true for 3rd gen (earlier than 2018) but 4th gen 2018-present it seems acceptable (but obviously not the best):

From 2021 Santa Fe manual page 1-5:
Gasoline containing alcohol and methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) are being
marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is a
gasohol comprised of 15% ethanol and 85% gasoline.
Do not use gasohol containing more than 15% ethanol, and do not use gasoline or
gasohol containing any methanol.

All the engines available in the Hyundai Santa Fe lineup can run on regular 87 octane. Ethanol is only allowed up to 10% in all generations except for the fourth-gen (2018-present), which allows up to 15% ethanol by volume. MMT and methanol are not allowed at all. Regarding fuel additives, Hyundai recommends the TOP TIER Detergent Gasoline.

So, let’s see if I understand. Food prices are soaring, the Russian invasion of Ukraine is disrupting the supply of wheat and other grain across many countries, and people are starving in many parts of the world. So let’s take an important source of food and use it to dilute gas and make it less efficient. Great friggin idea, NOT!

On a business show today they expected the cost per gallon of our current E10 blend to drop $0.10 a gallon at best. Given the reduced energy output of ethanol, the savings are a wash. Why risk your vehicle being damaged. For what it is worth, ethanol on the commodity market yesterday was selling for $3.56 a gallon.

If you take ethanol and add some sugar and other stuff to it to make it taste better, you basically have some really strong booze. I don’t want my truck to wake up with a hangover.

Sorry, the corn grown for ethanol is not suitable for eating. It is a special type designed/grown to optimize fuel production.

That said, I would be just as happy if they did away with gasohol. Don't like it or much of anything about it.

That said, It will make a very small impact on fast price for a limited number of people. So, better than nothing, but just barely.

My lovely old banger cant use E10, but has to drink E5.
It will be drunk as a skunk on E15!

It’s all posturing for influencing the base of the”RULING PARTY” smfhol.

I was under the impression that most cars can only handle E10, anything over that would damage your engine....can this be a way to make you buy an electric car , after your engine is destroyed ?

THEY want you to just plug it in.

Growing corn hurts the fields. The crops need to be rotated. The world could use the food.

Yep. All part of the plan.

Farmers do rotate crops. I come from a big ethanol-producing area, and farmers know how to get the most out of their soil. Usually rotate corn-soybeans.

But ethanol for fuel is an illusion anyway. America uses corn which is at best a 1-1 proposition, usually less. In other words the best you can hope for is to get as much energy OUT of the ethanol as you put into making it. Brazil is virtually petroleum-free, but their ethanol comes from sugar cane, which can be grown over much of Brazil and gives a 7-1 return, but which is limited here. We could use Sorghum, which gives back a 2-1 return, but to go that route means different farming machinery, different refining methods, etc., and could not be done overnight.

Long past time for alternate energy to run transportation. We cannot keep ourselves in this position because of oil.

I had a “flex fuel” suv. With regular unleaded I got 22 mph. With E85 the mileage went down to 17 mpg. Your actual mileage may vary. Do the math to determine if you are really saving any money using E85. Also, while you are saving money on gas with E85, you are paying more for food and other products that uses corn.

If going all the way from E10 to E85 "costs" only 5mpg then I wonder if the difference between E10 and E15 is even noticeable.
