It'll be fine. Just keep it fresh. I would switch to non ethanol if you have the option though. Over winter keep the tank full and some stabil in it too.

Yes,

Today's Gas works fine in the Model A. The ethanol does play havoc with the cork floats in the gas gauge though.

I add Marvell Mystery Oil to the gas to help.

We also add MMO. I believe fresh gas makes a real difference. That is one of the reasons we don't keep more than a quarter tank and any time.

Not a problem on a stock Model A but if you have added any rubber fuel hoses replaced them with some that are resistant to the new gas.

I've used it for years here in Florida with no adverse effects except for lower MPG in parades with temps in the 90's as well as general driving in those temps. Some have problems some don't. You need to tweak what you use for your car.

Yes, as long as you use it quickly !
Don't leave the eth. gas too long in your tank.

I bet by morning your "carb-o-rator" will be clean and you'll need a "pit stop"...

That's actually good news about fuel containing ethanol.

Ethanol does mix with any water that condenses in the tank. That happens often with cars like ours that aren't driven much, have an "open" fuel system, and that go through heat and cool cycles as the weather changes. The Ethanol holds the water in suspension.

On the other hand, fuel without ethanol just floats on the water that condenses in the tank. This can rust out the bottom of the tank over time and also cause hard starting and rough running since it is the water that will get to the carb before the gas.

Of course if there is too much water condensing in the tank to be suspended by the ethanol, the remainder will go to the bottom of the tank and eventually you'll experience the same rust and driveability problems as the no ethanol fuel.

The cure for the condensation is to add a couple of ounces of methelhydrate (gas line antifreeze) it will mix with the water and make it combustable.
