Has anyone noticed anything wierd recently with their car in regards to the manditory 10% ethanol content in gasoline? The mandate was across the USA, and most of Europe as well. My fuel economy went from about 6.7l/100km (35 mpg) to 8.5l/km (27 mpg) after the switch. That's a lot of fuel being wasted. Here in Germany, they introduced the manditory E10 blend at the begining of the year, and I've seen a ton of horrible effects. I've even had to put the factory intake back on to try to reclaim some of the FE I'm now missing. My biggest problem is that the engine my car has isn't designed to run on the E10 blend, and I know it's messing with the power-curve. Anyone else having any major problems?
