"I have a sneaking suspicion that the election in Greece may stir up oil prices this week, and we could see oil prices gain as markets feel more upbeat about the economic situation," said Senior Petroleum Analyst Patrick DeHaan. "While any gains in oil prices won't likely be immediately felt, the debt situation in Europe bears keeping a close eye on as it has far reaching global implications. Outside of that situation, West Coast wholesale gasoline prices are now among the lowest in the nation...their averages drop back under $4/gal," DeHaan said.
