As it turns out the feds icreased the excise taxes on diesel to 24.4-27.5 cents per gallon[cpg]. The states followed suit and increased there taxes on diesel as well. Then, of course, there's the local taxes too. All of these government agencies teamed up to put a whopin on all the 3/4 and 1 tonners out there. Over the road haulers took a serious hit as well.
The reason was supposedely to clean up or pay for diesel emissions{ Yeah, right}.
I've found the lowest tax rate seems to be Georgia @ 7.5 cpg for both gasoline and diesel the highest looks to be Penn. @ 31.1 for gasoline and 35.1 for diesel. Add that to the inflated refinery prices and throw in the federal taxes and Boom! we get more expensive diesel fuel. On the plus side, I have job security working for one of the big guys that raked in $36 BILLION in one quarter. Even as an employee it still pisses me off.
