| Well I certainly never said ethanol wasn't a good cleaner. It also mixes well with gasoline and water. There is a big difference in boats and cars. Cars usually consume lots of fuel regularly. Boats not so much. Fuel sits for long periods in most boats. Fuel tanks can and will collect moisture through condensation. Cold air, warm water. Warm air, coldwater. They are also used in moist environments so susceptible to even more condensation.
This is why they have water separating filter. Almost all boats and marine engines have this. Even my 15hp does. So some one else besides me recognizes the potential for water in fuels in a marine environment unless this is propaganda too. So let's just say there is a slight chance this could happen to some one. Ethanol can hold water well but when it gets saturated it separates. Not just the water but both the ethanol and the water at the same time. This renders the water ethanol mix unusable. It also leaves the gasoline unusable since the ethanol is used to give it octane and has now been removed. You now have a complete tank of useless fuel.
When gasoline is contaminated with water the water separates. The water of course is useless. The gasoline is still good. The water is collected in the filter where it can be removed. The gas is still good. Not so with E10.
You can test this on your own if you want. Its called science and it works very well. You will need a test tube, e10 fuel and water. Makes sure you have something to give accurate measurements. You will find out how much water you can add before it separates. It will be .5% of the volume at 60 degrees depending on the ethanol content. Less the colder it gets. It could be even less if the fuel already has water in it. Its alot of fun and a good way to determine how much ethanol is in the fuel you are buying. Be careful though because its flammable.
I definitely think you should try the experiment. It's great science.
Have fun. | |
