You will notice that your local gas stations in Michigan no longer post if their gas has ETHANOL on the side of their pumps. Ex Gov Granholm mandated that removal before she left us with our deficit. If you have a newer vehicle..including any gas engine (lawnmower, etc..)...you should be OK. However, older engines will be affected and it will possibly ruin the fuel lines since Ethanol has extreme additives that will eat the lines.
My friend's weed wacker is ruined because of the ethanol...and that was the Stihl mechanic who advised him. There are additives you can add to the gas to avoid the problem. Mobil and Shell and BP did not use the Ethanol until late last year. As time goes on, people with older engines will be affected. 'You Tube' has a lot of examples of additives to use to prevent problems. Guess what...Obama, if re-elected, vows to up the Ethanol content from 10% to a new mandated 15%! Warning ! Danger Will Robinson!
(Please...I don't want to hear the rebuttals from the Obama Lovers!)
