100% gas in my boat and lawn care equipment. Luckily there is a station in town that still carries it (at least they claim it's 100%). It is super expensive right now($5.69 at last check) but I look at it as preventative maintenance.

Yes sir. The recommended fuel for our 6.2's is 93 octane. I've tried the 10% ethanol and there was a noticeable reduction in horsepower and MPG so I stick with the ethanol free. My wife's truck sits more than it's driven and I tow alot and need/want my horsepower. 

 

Wow, that is surprising to hear.  I guess you gotta use what's recommended.  If the owners manual says to use that, I'd use it too.  First time I've heard of anyone using ethanol free premium in an automobile that gets used on an almost daily basis all year round.

We're lucky we have it here.  But I do wonder about the 100% claim, as that's pretty much impossible.  They usually also claim to have special cleaning additives and I know by law it'll at least contain 10% butane this time of year.  So even 89% gasoline would be pushing it.  But I'm trusting that it at least doesn't contain ethanol.

 

Best thing to do if you can't get ethanol free gas, is to just empty the tank and then run the engine until it dies.  Ethanol will affect gas mileage and power a little bit, but it's real harm comes from sitting around in your engine for a long time, unused, where it can draw in water and corrode the engine from the inside.  So running ethanol should be fine for most small engines, so long as you take the extra step to drain it after every use.  

It’s easy to test gas for ethanol.  Just check YouTube for how to do it.  I’ve tested gas from a few places and I haven’t found any ethanol yet.

When I lived in Ohio I never heard of it either.

Here in TN there are a bunch of people that do it.

I was told to use it for everything - riding mower, weed eater, chainsaw, bonfire starter ...

My in laws only use 100%, he has a full size gmc and she has a lexus SUV

I see a lot of people fill the truck up and then pull the boat up filling everything with 100%

My neighbor says he runs it after a couple of tanks of the corn syrup to clean it out ?

That's actually what I do with my lawn mower and snow blower every year too, even though I only use ethanol free premium in them.  They both have relatively small gas tanks anyways so it doesn't take very long to run the gas out of them.

 

In my outboard, I don't do that.  It has a much bigger fuel tank.  But then again, I only use ethanol free premium in it and I take it to an authorized dealer every October for professional winterization which includes fuel treatment.
