I have been experimenting with removing the ethanol from gas by mixing 1 cup water to 1 gal. gas and shaking vigorously, then pouring the mixture into a coned bottom container and letting it settle for about an hour, then crack open the draincock and removing the ethanol/water mixture from the bottom.You must start with 93 octane because removing the 10 percent ethanol will bump down the octane by 2 to 3 points. I have used it in my 2-stroke dirtbikes and it makes a big difference in starting and all around performance. I also used it in the lawn mower and weed-eater and they run and idle much better. I will be putting some in the boat soon. Has anyone else tried this method yet. It may sound crazy but from what I have seen it really works.
