How to save more on gas in Cranston
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Rhode Island
Rhode Island shares pipeline and tanker supply with Massachusetts and Connecticut, so pump prices closely track Boston-area trends. The state gas tax is around 35 cents per gallon, higher than Connecticut and lower than Massachusetts. Providence sees the most competitive pricing in the state, with Costco in Cranston and Warwick, BJ's Wholesale, Sam's Club, and Cumberland Farms competing aggressively. The state's small size and dense retail competition keep prices reasonable despite New England-wide RFG requirements. Newport and the South County beach communities sometimes run 5 to 10 cents above Providence during peak tourist season because of summer demand spikes, with limited Costco and Sam's Club presence pushing more Newport buyers toward Cumberland Farms and independent stations.
