Since the conversation is evolving a little. Daily driving I use ethanol blended but in my cars that sit more often exspecially through the winter months non-ethanol blend. Better shelf life without the corn additive.
Speaking of additives. seems to be past marketing would claim the higher grades had the better additives… don’t see that promoted much anymore around here. Anyone else know if you move up in grades you get more detergent as well or no?
