Ethanol is bad for "Vintage" engines

So generally you fill the tank for storage? I was putting my old drained gas into my vehicles as well but didn't want to admit it incase it is a big no no!
 
I always just fill the tank to limit moisture build up. Change the oil in the spring and other routine maintenance such as the chain. I’ve never had any issues. YMMV

Maybe I’m doing it wrong 🤷‍♂️

This is what I was recommended to do by a reputable shop. This is based on being stored in the garage. Wash bike and dry, I prefer using the leaf blower, works great! Fresh gas in tank full with stabilizer, should ride a bit prior to storage to get stabilizer mix into carbs or injectors. Oil change. Trickle charge battery. If you have separate rims/ tires, swap out and put good ones in the house. Any race compound tires, in the house for storage. Bike on stands preferably. Bike cover. Do not start the bike till spring. I was told that it is not recommended because the starting and stopping creates condensation/ moisture and is the worst thing for the bike. The oil change is done before storing so that it is resting with clean oil and is ready to go in the spring.

Too much overthinking.

It’s going for a short winter nap… not a big deal for a motorcycle. Fill it up, protect the battery and focus the next few months on choosing a good oil.
 
Sorry. I WAS WRONG. I apologize wholeheartedly for leading you all astray
We got ethanol blended fuel in the 1800s
... and for all youse with the "eats rubber seals and gaskets" we got Buna-S in 1942. (Gaskets and seals and fan belts and tires aren't made of rubber, they're made of a derivative of Buna). Buna is ethanol resistant.
Over the years, there's been times where a gasket/seal manufacturer has screwed up the formula for buna... and their seals/gaskets leak
Sometimes the oil manufacturers screw up the recipe for their ethanol blended fuels, which causes seals to leak.
Sinking plastic carb floats is not a problem particular to ethanol blended fuel motors, THAT problem has been around since BEFORE plastic floats, the brass ones sink too, in "pure" gas. (and the ONLY carbs I have heard this being a problem is Amals. Amal has "new and improved" ethanol resistant floats... but if your old one work... they work. No worries).
 
Is this true? I thought ethanol had a lower energy content than gasoline? Makes you wonder what else is wrong with that article.

"By 1896, horseless carriages (cars) were showing up on roads in Europe and the United States. Because gasoline is so cheap and abundant, and also because ethanol is taxed at a high level, early US automobiles are adapted to gasoline from the beginning. Racing cars, on the other hand, usually used ethanol (and other alcohols) because more power could be developed in a smaller, lighter engine."
 
Want a conspiracy theory?
Standard oil spent most of the '30s and millions of dollars to get ethanol blended fuels off the market as it cut into their profits.
So the current "ethanol is the work of the devil and is trying to destroy my car" come from a dis-information campaign from Standard Oil... again.
Or if you just want to HATE ethanol blended fuels: a lot of the information we have about using ethanol as a fuel came from the Nazis. They had limited access to oil in WW2, and wanted to use the little oil they could get for lubrication (it's cheaper and easier to synthesize fuel than lubricants)
Ethanol blended fuels is a NAZI plot.
 
This single page seems to have conflicting statements in the same paragraph:


Fuel Economy and Performance​

The impact to fuel economy varies depending on the energy difference in the blend used. For example, E85 that contains 83% ethanol content has about 27% less energy per gallon than gasoline (the impact to fuel economy lessens as ethanol content decreases). FFVs are optimized for gasoline. If they were optimized to run on higher ethanol blends, fuel economy would likely increase as a result of increased engine efficiency.

Ethanol also has a higher octane number than gasoline, which provides increased power and performance. For example, Indianapolis 500 drivers often fuel their race cars with E98 because of its high octane. The Co-Optimization of Fuels and Engines initiative researched the potential to improve engine efficiency through the use of ethanol blends and other high-octane biofuels.

Not in 1896.
In 1896 you bought gas at the drug store in a sealed can and you didn't REALLY know what was in the can.
Today's gas is better in every way. More power, cleaner burn, less residue, less motor maintanence
Ethanol is lower in energy, higher in octane than modern gas.
 
To optimize for ethanol (any alcohol), you have to run a MUCH higher compression ratio.
I know guys with drag cars that run methanol... you NEED minimum of 15-16/1. I know a guy running about 25/1 (I used to build him hi output starters... so the thing would turn over to start. He runs the ignition timing at 60 degrees BTDC) (60 degrees is almost twice what you'd run in a gas motor)
Indy cars run methanol so they can run the compression they need to make the power they need, gas wouldn't work. Funny cars? same deal. (Buddy's methanol fueled Mopar big block uses over 5 gallons of fuel per 1/4 mile run).

We've all heard "There's no replacement for displacement"... well there IS a replacement: compression (and RPM)... and folks are playing with compression where gas just won't work anymore
Bring on the methanol!
