It’s what I use in my Honda’s. It’s also the fuel of choice for DW Mercedes E-350.

Any fuel can go bad if it sits long enough, that's why stabilizers where developed, people used them way before Now. It reminds me of the diesel change in the 90's , it was said it would blow all your seals and glow plugs. Simple, either run the carburetor dry or add the keep fresh stuff or run it monthly. No need to buy expensive non E gas, Shell and Exxon just loves you. Carborators have ALWAYS varnished.

Spock, don't know why my statement quoted you, it was just a general statement I made, my phone has a mind of its own. Has nothing to due with your choice of gas for your car.

Actually the Mercedes E-350 has a requirement of 91 octane, DW uses 93 octane. Her fuel is usually fifty cents more a gallon than my diesel but it’s a car she has always wanted.

Yes the ethanol sbsors water but unless you get to the point where it reaches saturation and you get phase separation, you won't have an issue.

Ya Right !!!
I totally disagree with your friend the Chevron Chemical Engineer !!!
I have receipts for a new Carburetor & a new Fuel Pump on my Generator from last year,,, for over $800,,, that proves to me that Ethanol is GARBAGE !!!
I now keep Snake Oil in my fuel !!!

If the Mercedes requires 91 octane she is doing it no favors by using 93 !!!
93 octane could do more trouble that good !!!

Well it’s a 2013 and no trouble with the engine, 91 octane is hard to find in ethanol free gas. We don’t use ethanol fuel in the Mercedes

That might be a good reason to buy 93,,,
As long as it does not confuse the Computer ???

Proves my point! A carb is never going to be damaged by ethanol. In fact, ethanol if anything will clean the carb! Gotta love the scare theories though!
I think I will believe the chemical engineer!

The engine has knock sensors to adjust the timing to the fuel.

I guess all the service tech @ OWAN/Cummings should talk to your Engineer buddy !!!

Ok fellas. Let's agree to disagree. Y'all are talking in circles.

I use ethanol-free premium gas in all my small engines. I always put Sta-Bil in the gas can, too, since I don't use a lot of gas in one season - the gas might sit there for several months. So all the fuel they get is non-ethanol with Sta-Bil treatment. The lawnmower and snowblower are run dry before storage.
I also use ethanol-free gas for the last fill-up when storing my 1982 Gold Wing motorcycle for the winter and add in some Sta-Bil, too
For what little extra it costs, I choose to use ethanol-free gasoline for piece of mind. If the Sta-Bil is duplicating the ethanol-free benefit, so be it. It's cheap insurance.

Not just Babcock, car manufacturer's say so too.
Modern gas engines use the computer to adjust timing for all conditions, including fuel. It's how they achieve max efficiency.
When "knock sensor"says too much advance for the fuel and conditions the computer retards spark.
A far, far, cry from distributor's with vacuum and centrifugal advance mechanisms.

I was not disagreeing,,, I know very little about today's autos !!!
I can figure out how to change the oil & that is about it !!!
Unless FORD has change there thinking,,, they always said if an engine was setup to run on 87 octane,,, that it was a waste of money to run higher octane fuel !!!

That is correct. Most of the time, the timing parameters are set up to retard spark on a knock condition but will not keep advancing until knock if a higher octane fuel is used. However, there are certain engines, for example the Ford Eco boost, that will do that.
When I worked in the auto electronics company, we worked with Toyota racing. They used our cylinder pressure sensors and changed timing on each cylinder independently. Certain engines now do the same thing using various methods to detect knock. We would actually do a signal analyses on the pressure sender output to detect right when a ping was detected and back off the timing slightly on that cylinder as well as modify fuel delivery.
