WEST SPRINGFIELD, Mass. (WWLP) - The average price for a gallon of regular gas went up this week by 12 cents to $3.67.
And some experts are worried that at this rate, we'll be paying $4 per gallon by spring.
Usually gas prices rise around this time of the year because of refinery activities.
Many refineries temporarily close for scheduled maintenance, and they begin the complicated process of switching over to summer blends of fuel.
The switch to summer blends is required to meet air quality standards, but they cost more to produce.
Oil prices have also gone up.
But experts say seeing this kind of increase is still unusual.
Usually we see a weekly jump of 10 cents between March and May.
So the 22News Pump Price Patrol is working for you with a look at some of the area's lowest gas prices.
$3.61 buys you a gallon of regular gas at Pride on Montgomery Street in Chicopee.
You'll pay $3.59 at Shell on Boston Road in Wilbraham.
And $3.63 at Pride on West Street in Springfield.
