While prices differed by more than 50 cents a gallon across the country, Kentucky's rates stood at $1.66 for regular gas, $1.78 for midgrade and up to $1.87 for premium. Average price for diesel was $1.62.
The U.S. Energy Department is predicting prices will go a dime higher during April and May. Triple-A reported drivers in California, Hawaii and Nevada had the highest rates -- over $2 a gallon. South Carolina and Oklahoma had the cheapest gas, about 40 cents a gallon less than the western states.
Although Middle East producers are cutting production, this is less than half the cost of gasoline. The Department of Energy lists refining costs at 19 percent, distribution and marketing at 9 percent and taxes at 26 percent.
