Would you believe that the E0 gasoline sold at a station is the same formulation of detergents and additives as the Ethanol mixed fuel sold at the station? We have a Marathon station who sells both. Nobody at the station seems to know the answer.

What if they are the same? Long as it is zero alcohol fuel is all I would worry about.

If anything i would think the E0 fuel would have more octane additives like toluene or xylene since there is no alcohol to help with the octane rating.
 
The local Casey's had E0 87 octane for a while, then they took it out. I email them every 6 months or so and "beg" them to put it back in. Same "our corporate thinking has....................................." Nice way to say NO!!! Got to run it for over 2 yrs. Always gained 2+ MPG using it.
 
All of the available E0 fuel in my area has a "Not a [pick your brand] product" label on the pumps. None of the stations specify where their E0 comes from. It's just a crap shoot and I hope I'm getting what I pay for.
 
All gasoline is required to have some detergent in it. The cheap gas usually has the bare minimum, probably?
The name brand gasolines claim they have more. Do they really? Who knows.

I’m not sure why the attendants at the station would know or care. This is like asking your grocery store what farm the milk came from.

Just my $0.02

No ethanol is mixed at the station. All additives are added to the total volume at the terminal, with or without EtOH.

Some places such as Costco inject the additives at the pump but this would also be on the total volume being dispensed.

I'd expect an adequate level of additives, as E0 is a "premium" fuel despite being low octane.

This much I know, E0 helped my 5.4L F150 achieve as much as 2MPG more. Not only did it run better, but the engine never developed any significant deposits, never had any engine codes or faults, and always performed perfectly. It made it to 200K miles before my wife totaled the truck. Engine still runs perfectly, I start it up every week.

The truck was totaled but you kept it?

Possibly, but Marathon dropped top tier from their fuels a few years ago. It's also possible that a particular station may be sourcing the E0 from elsewhere.

Most places that sell E0, at least in my area, sell the CBOB pipeline "premium" as such. That's been 90 pump octane E0 for several years without the ethanol dosing which is all done at fuel delivery. It used to be 91 pump octane. A couple stations still haven't taken the 91 rating off their E0 pumps. Then there are some very few stations that sell both 87 PO and 90 PO E0. They must use blender pumps, since pipeline "regular" without ethanol is only 84 PO.
 
Our local Holiday stations claims Top Tier for their fuels and I don't see any exceptions so I'd assume their 88 octane ethanol free would have the same level of detergents. I have moved to using this fuel for everything I own that has a carburetor or with fuel that sits for extended periods of time (Honda Pioneer 1000 SxS, etc.)
 
Been hitting up the Cenex and Shell 89 e5 and got 37mpg. Both premium 91&93 clear and 87 was e10 so I'm okay with the 4-6%. Was blistering hot out today and these K series GDI calm down on dilution with a higher grade.

My buddy used to tune K series and he was adament that 88-90 was where non boosted K series ran their best.. Time will tell although in the heat I can say yes he was right. I think in winter it will be 87 with e0 87 or 91 e0 as a top off <3 gallons due to winter.
