Many analysts are expecting the national average for fuel prices to rise above $4 within the coming weeks, although it may fall back down again shortly thereafter.According to USA Today, the national average is currently $3.91, although prices have spiked above $4 in nine states, as well as Washington D.C. Some major cities like New York and Los Angeles have also seen prices above $4 for several weeks now.

However, a small amount of relief may soon be on the way. Many oil refineries have been operating at reduced capacity as of late as they switch over to what is known as "summer blends" of gasoline, mixtures attuned for warmer weather. As production ramps up again, gas should be more readily available and will likely fall back down below $4.

Still, the primary factor behind high gas prices continues to be unrest in the Middle East, which could possibly be exacerbated by the recent death of Osama Bin Laden.

With the future relatively shaky for fuel prices, drivers may be experiencing an unexpected increase in their monthly expenditures. Those who want to save more money each month may want to consider auto loan refinancing, which can leave them with more cash to put toward gas prices and other expenses.
