Marinas sell it for boats. Marketing thing. Most say it is just expensive gas.

thanks for all the informed responses. sort of hard to get a consensus from it all...guess i'll stick w/87 or 89 & continue to treat w/stabil red & their version of ethanol treatment (2 separate products). & just rotate supplies best i can during off season. yes, would be good to hunt down non ethanol for the small engines, but will stick w/same gas for everything like i do motor oil..... btw, (being of old school) do you remember the days when you could dial in the octane rating @ the pump? (sunoco i think) or was it the leaded additive? thank again, cheers for the season......

I would have thought the same thing, but one station that sells it, only sells non-ethanol gas and has 87,89 & 91 grades + Marine grade. I will ask him next time I stop there what the Marine grade is.

my 2cts/ marine gas is a marketing ploy-it is 100% gas,also called conventional gas,ethanol-free gas or in other words "gas like it used to be"
Here in the southeast, 100% gas is not available at all terminals and price varies wildly among different suppliers.
E-10 gas or gas with 10% ethanol is a death sentence to small engines or storage that sits with no movement for extended periods of time. That stuff loves moisture, in fact it can actually separate in tank,become very cloudy in appearance and becomes DEAD GAS.Some of these small engines parts are not even compatible with E-10 gas/ o-rings,gaskets, etc
my thoughts-the older gasoline engines are better served by running 100% gas w/93 octane/you know when it was built it ran on leaded gas/the 93 octane probably burns a little cleaner ?
As far as all the gas being the same/ not really-it all comes thru the same pipeline but each branded supplier has their own additive package that is injected at time of loading at terminal/ some even put markers in additive package so if they want to take a sample at a retail location,that marker better show up or they know you are trying to sell unbranded product thru a branded site, a definite no-no.
You just can't go wrong with 100% gasoline.......... no problems-no worries

3 years ago our marinas stopped selling ethanol free gas. All we can get is 89 octane E10.

I remember Compression Ratio's of 11 to 1 and Higher. now a 9 to 1 or close is the norm. You needed the high Octane so you would not get pre ignition. Sunoco 260, 240 and 220.
It might have been suggested here already....
Consider shifting to Stabil blue/green product, that they market for marine use. It is more $ initially, but not in use, as the treatment ratio is better than red Stabil.
According to Stabil, they have boosted the level of detergents in the marine version. Ethanol aside (agreed it is a big issue), what you should be getting in Premium gas is a better additive/detergent package. If you are using Stabil already, you can accomplish the same by shifting to Blue, for probably less money than using red.
