"With some European resolve in regards to the Greece debt situation, oil prices took off late last week," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst. "While the national average has remained relatively subdued in the last couple weeks, we may see a slow climb in the national average this week. The national average for gasoline has barely climbed, even as crude has gained some $20/bbl from the lows we saw nearly six weeks ago. As we approach heating oil season, we'll also see support for diesel prices, which is sure to frustrate diesel consumers, who are paying as much as eighty cents more per gallon than gasoline consumers," DeHaan added.
