Although gasoline prices have been dropping as of late, prices in Connecticut can still vary by more than $1 per gallon depending on where you fill up.

The past week has seen prices drop by 0.5 cents per gallon, averaging $3.67 per gallon on Sunday, according to GasBuddy’s daily survey of 1,540 gas outlets in the state. But prices vary widely, ranging from a low of $3.45 for a gallon of regular at Costco in Enfield to a high of $4.59 for a gallon of regular at a Shell station in Stamford.

In Wilton, both the Gulf station at 287 Danbury Road and Citgo at 384 Danbury Road are charging $3.71 per gallon of regular.

Including the change in gas prices in Connecticut during the past week, prices Sunday were 35.9 cents per gallon lower than the same day one year ago and are 13.3 cents per gallon lower than a month ago. The national average has decreased 7.8 cents per gallon during the last month and stands 26.8 cents per gallon lower than this day one year ago.

However, prices may not stay this low for long.

“The national average has begun to tip-toe higher in the last week, led by states in the Great Lakes and West Coast where gasoline prices have crept up considerably in some areas over the last week,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.

“Oil prices have rebounded, and with the recent strength in stocks trickling over to commodities, I do expect retail gasoline prices to inch up in the weeks ahead. The biggest increases will be along the West Coast where gasoline supply remains at an ultra-tight status, but prices will also increase in many other areas, led higher by the rally in crude prices we’ve witnessed in the last week,” he said.
