If I use the Startron, can avoid empting my fuel tank? My tank is plastic. I don't see many deposits in my fuel filter other than the gel that I understand is from mixing the two fuels.
I made sure I ran all of the pre ehtanol fuel out of my tank. After all I read all over the internet I did not want to take a chance on mixing the two. I would do the same again. Get rid of the gas, clean the tank, and refill it.
