Gasoline starting on May 1.

the EPA is only allowing the sale of it not mandating it. like said by a few others, not likely to happen at a station near me.
 
MIne says 10% max higher alcohol content may damage
Yeah. The cars that can use 85% usually have a big yellow fuel Cap, and a Label stating that it can be safely used by THIS Vehicle. If you don't see that, stay away from the stuff.
Several Rental vehicles that I used in 2010-2020 decade came with such labels. Several time the rental agent would point it out and then say that they would really appreciate me not using that fuel.
 
Racers have been blending hooch into their gas for years to get extra horsies, especially with forced air intakes. I have a Nissan Frontier with a supercharger and a still, and have done this myself, just for fun.
The big unknown with commercial blends is the purity of the ethanol being blended in. I can only get to about 87% with my setup, which means 13% of what I put in my tank is water. One reason I only did it once. Ran like a striped ass ape, and the water is more than likely burned with the fuel, but I have this mental image of a separated puddle in the bottom of my tank just waiting to get sucked into the fuel line.

I thought everything 2001 and newer was supposed to be okay with the E-15. Not that I would use it in anything of any year.

Not all.
No, not all cars built after 2000 can use E85 gas. While most vehicles manufactured after 2000 are compatible with E15 (15% ethanol), running E85 (up to 85% ethanol) requires a vehicle to be specifically designed as a Flex-Fuel Vehicle (FFV).

  • FFV Requirements: To safely run E85, a car must have specific sensors, fuel lines, and engine calibrations to detect ethanol content and adjust performance accordingly.
  • Compatibility Check: Only vehicles with an FFV badge, a yellow gas cap, or a label near the fuel filler indicating E85 compatibility can use this fuel; standard cars built after 2000 generally cannot.
  • Risks: Using E85 in a non-FFV vehicle can cause engine damage due to lean conditions, corrosion of rubber seals, and improper fuel management.
To determine if a specific vehicle is compatible, owners should consult their owner's manual or check for an FFV designation on the fuel door or dashboard.
 
I just read the manual. it says E-10 or less.

"Do not use fuel containing more than 15% ethanol or E85 fuel"

I was thinking E-85 meant 15% ethanol, but no, a Brave Browser Search says;

"E85 fuel contains between 51% and 85% ethanol, with the remainder being gasoline. "

There is a tremendous difference between E15 and E85.
Yep, there sure is, but I had them confused as 85 is 15 below 100, and I somehow incorrectly assumed one was 85% gasoline meaning 15% ethanol.

I do not recall ever seeing either one and I also would never use either in anything, so it really doesn't even apply to me.

E = Ethanol G=Gasoline. so E-10 10% booze e-85=85% Booze.

Yup the gas tank, only place you mix gas and booze.

True story: Standard Oil back in the day in the winter advertised "My Advice Sir, Get De-Icer"
(Worked too I might add, but the story is not for this post save to say I switched to Standard due to fuel line freezing)

De-Icer turned out to be HEET brand gas line anti-freeze the drivers would add at time of delivery.

It's pure alcohol.

Worked too.
 
So if they end up doing this E15 thing I wonder if it will replace the E10 or it will be a separate nozzle.

"Yes, E-15 gasoline is typically dispensed through a separate nozzle.

  • Visual Identification: Pumps dispensing E-15 are federally required to have a conspicuous yellow or orange label stating it can only be used in 2001 and newer vehicles.
  • Labeling: The fuel is usually marked as Super 88, Unleaded 88, Regular 88, Clean 88, eBlend, or Unleaded 15, rather than Regular 87.
  • Blender Pumps: While some stations use "blender pumps" that mix fuels from the same nozzle, these stations are also required to provide a separate E10 pump for consumers who wish to avoid E-15."

E-15 (up to 15% Ethanol) replacing E-10 (up to 10% Ethanol) fuel is what we're talking about here. E-85 is completely different.

I would not count on that yellow sticker. After all they used to require it at 5 and 10% as well but that requirement went away .
