I agree with Rick on Hess for what is't worth. Best bang for your buck so to speak. I commmute three counties for work every day, and find that they have the best consistancy from station to station. Texaco "premium" diesel seems to give a LITTLE better kick in the pants, but the $.30 a gallon differance doesn't justify the addition cost per tank. Only one Hess (in Brooksville) publishes the cetane rating on the pump that I frequent.
