The price of gasoline has spiked in just the last week. It's up 18 cents to $3.54 a gallon, the biggest weekly increase in two years.
Analysts say the following factors may be fueling the price hike:
- A stronger economy.
- The price of oil has been climbing steadily in recent weeks as many refineries are doing maintenance at this time of year. It's close to $100 a barrel again.
- Tensions in the Middle East.
AAA officials say, if Mideast tensions don't escalate, gas is unlikely to hit last year's highs.
