Unleaded vs. Super Unleaded
Here in Iowa, super unleaded (10% ethanol) is usually about 8-12 cents a gallon cheaper than the regular unleaded blend (I'm guessing due to many ethanol plants in the region). I'm not sure if this is the case for many of you or not, but I was just curious as to which blend you fill up with?
Naturally, the ethanol blend is probably the most popular here since it's the cheapest, and that's always what I used to put in my car. A few weeks ago I switched to regular unleaded our of curiosity. While I had been averaging 33-35 mpg, I got 37 on the last tank. Obviously I'll need to try it over a handful of fill-ups to know for sure, but if that increase holds, that probably makes up the price difference.
While the ethanol industry insists otherwise, I've also heard from a few sources that the ethanol-blend might be a bit harder on the engine.
