Here in Eastern SC, the price of unleaded gas has gone up to about $3.20 from around $3.00.

At the same time, diesel has gone from $3.25 to over $4.00 in some areas.

20 cents versus 75 cents maybe they need to pass a little more price increase on to gas users not just stick it to people that use diesel.

The real question we need to ask is why the US Federal Government needs a 50 cent a gallon tax on top of the local and state fuel taxes. They haven't done a thing to produce, transport or even market the fuel they are taxing. Sounds like free money for Uncle Sam if you ask me. Yes, I know it helps to maintain the roads we ride on every day.
The quickest way to remove government waste would be to invent a shovel with a kickstand.

But, I could be a little biased, I am a trucker.
