Anybody have experience with E15 gas? I often get gas on the way to the lake and was not too worried about the E10 being in 87 octane fuel. I wonder, will this be another option to purchase at the pump or will it replace the current E10 that's available.
I have an older 90's 2bbl carb on my 4.3 merc

Can't stand the junk.

I've seen and heard of it messing up cars even that aren't built to handle more than E10. Dad's buddy did it once and had to get the tank drained it ran so bad.

Wife's car is even rated for it and developed a miss after running a tank of E15 once.

I only run non-ethanol in the boat for a reason.

I'm not worried about it. If your engine ran OK on E10 I cannot imagine E15 will be a problem.

Honestly, I have not heard of any ethanol-related engine issues for a long time.

The E10 fuel is approved for use in your late-model marine engine, but the E15 is absolutely NOT approved for use in marine engines. Outboard and sterndrive engines have been designed and tested to operate on E10, but not on E15.

OPIE and NMMA has been pushing to keep E15 out of equipment and motors for over 12 years now

Its not good in any non-multifuel system

Its not a performance thing, its a your motor will fail type of thing. Small engines for lawn and guarden and marine have had warning stickers for the past decade

Don't know about IB motors, but most OB motor manufacturers recommends max E10 fuel contents, E fuels will screw way faster and prematurely general rubber and plastic components, o'rings and fuel pump's diaphragms compared to non E fuel use. In Brasil where they use much higher than 15E fuel contents are having tons of related problems with OB use...

Happy Boating

If you look at the specs for current gas powered yard equipment (e.g., small two stroke air cooled motors) they are rated for a 50 hour life expectancy. So no matter what you burn in them they don't last. Best bet is to add a touch more "quality" oil (Stihl Ultra) and run it like you stole it.

There's one gas station near me that still sells non-ethanol 91 octane gas. That's all I run in ALL my stuff; truck, motorcycle, chainsaw, weed wacker, etc...

The bigger issue is the is something that is inherent to using a gas/alcohol mix:
inaccurate mix by tanker truck drivers
when the E-10 change over started here in 2004 or so, samples were tested and many had more than 10%. That combined with the cleansing effect of ethanol caused big problems in older fuel systems.
But yes bringing our energy industry back to where it was in the 1970s was a horrible move of poor judgment and a lack of standing up for what just makes sense. I am old enough to remember
"energy shortage" #1, 1973/1974 this was NO shortage, it was pure political hostage taking to retaliate for our backing our ally in the middle east
"energy shortage" #2, 1979, the Shah of Iran is deposed, more politically induced problems, again no shortage
in college they made us read a book called "The Limits to Growth" (circa 1974) they predicted that we'd be out of oil by about 1985.
anybody remember what happened about then? gas prices dropped from about $1.50 a gallon to about .85
So much for predictions, and the accuracy of the media's take on things.
