Ethanol-blended fuels can cause problems and damage to engines, especially older ones.
Unfortunately, the ethanol molecule separates from the petroleum molecule with the slightest moisture and clogs fuel lines.
Using Amsoil PI for gas motors (cars/trucks) and Quickshot for Powersports is very cost beneficial and a problem avoidance tactic.
You also get better fuel economy.
