BoostnBenz, your location isn't listed, where did you say you were, Michigan? You are in one of the few states that is able to get 50 cetane minimum Amoco Premier. Seek it out, and use it exclusively, it's by far one of if not the best fuel in the country. Minimum 50 cetane, low aromatics, low sulfur, better basestocks, great additive package, etc. You will have quicker starts, better mpgs, and more power. It's worth a bit of a drive to use.
Where in Michigan are you? There are a few places that sell Amoco Premier and Biodiesel. One place called Wacker Oil, sells a B20 (20% biodiesel) mix of Premier and Bio, talk about a sweet sweet mix!!!!
