Watched something the other day about the ethanol fuel and the damage that it does to the vehicles that it runs in. You see, when they say that it burns cleaner, well, that just means that it produces less emissions. There are a lot of vehicles that have had issues with injectors going bad, oil going bad quicker than normal, etc etc etc. I guess that the ethanol really takes a toll on the oil the most. If you do not follow a strict changing schedule, then better start or you could end up with issues in the long run.
