"After oil prices briefly dropped to $75 per barrel in the last two weeks, we've seen a mini-rally take place, driving prices up to a more recent mark of $82 per barrel. The volatility we continue to see in oil prices isn't surprising, and will likely continue as a fragile economy and some upbeat investors play the market," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst.
"What this means for motorists is a continued roller coaster ride at the gas pump. While I don't expect a huge of movement in either direction, these up and down fluctuations in gas prices will become the norm ahead of a volatile Spring 2012 time period," DeHaan adds.
