OT, but you don't have No. 1 diesel or blended diesel in the winter?

Last I checked E85 is not 15% ethanol....E15 is 15% ethanol. E85 is anywhere from 53%-85% ethanol.

As Dillonbuck has explained, blending is the norm - including octane derivation. Old practice. In the mid 1950s I worked R&D at a Sunoco refinery helping perfect a pump that blended low octane with a high octane concentrate - your blend level selected at the pump - and that setup was quite successful back in those days where a range of octane ratings responded to consumer needs. The concentrate itself - Sunoco 260 - was a big deal for those of us who raced high CR engines. Some brands advertised a few proprietary additives back then - delivered in the tanker - probably added at some distribution point as Dillon buck explained.

Today - stay away from ethanol in small engines and any vehicle where it will sit in the tank for very long. Alchohol takes on H20 and also eats some components.

It's actually 70%-84% ethanol depending on whether you have Class 1 80%-84%, Class 2 75%-79%, or Class 3 70%-74%. No way to tell which class you're buying because the pump will still show E85. It takes around 25% more ethanol to make the same power as gasoline.

WASHINGTON, DC – As the Memorial Day weekend kicks off the summer boating season, Boat Owners Association of The United States (BoatUS) and National Marine Manufacturers Association (NMMA) urge boaters to be mindful when selecting fuel for their boats, especially as the federal government’s Renewable Fuel Standard (RFS) is increasing the risk of consumer misfueling. Even one mistake at the pump can be the source of expensive, warranty voiding repairs and dangerous engine failure.

“Boaters can’t assume that every fuel sold at gas stations will work in marine engines,” said BoatUS President Margaret Podlich, “Boats can only run on 10% or less ethanol content (E10) fuel – and we know many boaters prefer to use ethanol-free (E0) when possible. Unfortunately, as a result of the federal ethanol fuel mandates (RFS), boaters may face a much harder time this summer finding the E0 fuel they want. And with more E15 (gasoline with 15% ethanol) forced into the fuel supply by the RFS, the threat of accidental misfueling—especially at gas stations with blender pumps—is growing.”

“Our priority is always to keep boaters safe,” said NMMA President Thom Dammrich. “By increasing the share of fuels in the marketplace that are unsafe for marine engines, the federal government’s RFS is putting boaters at risk. Research shows the costly price of accidentally misfueling a boat with E15 can include stalling, corrosion, fuel leaks, damaged valves and complete engine failure – each of which could put boaters and their safety in jeopardy. Now more than ever, with E15 on the rise, the threat of misfueling is real.”

An estimated Ninety-five percent of boats are filled at retail gas stations, but a 2016 Harris Poll commissioned by the Outdoor Power Equipment Institute found a startling 60 percent of consumers believe any gas sold at retail stations is suitable for all engines and products. Further, only 36 percent know E15 is harmful to some engines – with just five percent aware that its use in those engines is also illegal.

The federal ethanol mandates, known as the RFS, require increasing amounts of biofuels—including corn ethanol—to be blended into the US fuel supply every year. This growing mandate forces higher quantities of fuels such as E15 into the marketplace, often at the expense of E0 ethanol-free fuel, and even though fuels with more than 10 percent ethanol are illegal to use in marine engines, motorcycles, outdoor power equipment and cars model year 2000 and older.

Though the government is aware that the RFS is changing the makeup of the fuel supply, it has undertaken no serious education campaign—beyond requiring small warning labels on fuel pumps—to inform boaters and other consumers about the problems they may face from improper or accidental fueling. The boating industry and others have sought to fill the gap and inform the public about the need to be vigilant when fueling and not assume that just because a gas station sells several fuel types from the same pump that each is suitable for marine engines.

I don't run ethanol in my Husky lawn tractor or chainsaw or weed-trimmer - ever. I've never had to have a carburetor rebuilt on those yard implements, either.

Maybe those yahoos on you tube videos showing how to remove the ethanol are on to something for small engine use.

I have run ethanol gas in every chainsaw and outboard I have ever had. I have a 2000 Yamaha 40 that has never missed a beat and a 1996 Husky saw that has never had problems. I add StaBil to all my gas tanks at each fill up. Your results may vary...

BINGO!!!!!!

Back in the 80's I ran a motor fuels lab for a couple of companies and later ran an ethanol plant and did some pilot production of ETBE, an ether derived from ethanol. The only ether to see large scale use in gas was MTBE which was nasty stuff and easily absorbed into groundwater. It hasn't been used in years. Non oxygenated means that there is no alcohol or ether in the gasoline, the same thing as no alcohol.

I haven't worked in the fuels industry in over twenty years and have no dog in this fight. I would not run a 10% ethanol blend in any two stroke or marine motor but have had no problems in newer model cars or motorcycles. Keep in mind that it was politics that led to ethanol being mandated in gasoline. It was a means of keeping corn prices high and Nebraska, South Dakota, and Kansas have more senators than New York and California. Ethanol was something that Bob Dole and Tom Daschle were in complete agreement on and that made it unstoppable.

It's a matter of avoiding pre-ignition - no need for higher octane if this is not an issue in a given engine setup.

Yep. Three of my automobiles require 93 octane.

Yes. Star Tron is even better, but expensive, like everything else about alcohol.

Unless your a corn farmer.

You can run 91-93 octane with Sta-Bil and be perfectly fine. I have a 15 year old two-stroke Wal Mart Brand weedeater that fired up once more this spring.

FUEL GOES BAD if you don't add a preservative.

Both are the same!

The term oxygenated goes back to 1994-1996. At that time up to 10% ethanol (mainly, though some states used MTBE) was added to reduce tailpipe emissions of carbon monoxide. Now we put the same stuff in and call it an ethanol blend.

That is 100% correct.
