Find Cheap Gas on Cape Cod

Te best gas price near Provincetown seems to be the cash price at the Mobil
station in South Dennis. just off of Route 6, near the Patriot Square Mall.

When I noticed the cost of gas in PTown the other day I found a variety of prices at our four gas stations.
The Sunoco station on Shank Painter Road, is closed for the winter, but is scheduled to reopen in the spring
The Tedeschi station (at Commercial and Bradford streets) sells a gallon of regular gasoline for $2.31, with 6¢ Tuesdays, where the pump price is automatically discounted by 6¢ at the pump, if you gas up on a Tuesday.
At the Gulf station, across the street, the current price is $2.46 for a gallon of regular, every day of the week. There is no significant difference in the quality of the gas sold by small independent stations compared to that sold by brand name refiners, since federal regulations govern octane and cleaning additives used in all gasoline sold in the US, though various major brands might include extra additives of their own. Any distinction in performance, though, would be just the tiniest difference in gas mileage, so bigger does not mean better. You may even choose to pay a higher price in order to support a small, independent gas station rather than a corporate giant.
Cumberland Farms, on Shank Painter Road, currently gets $2.37 per gallon, which will be discounted at the pump by 10¢ per gallon if you pay with their SmartPay card, which automatically makes a withdrawal from your checking account, once you set it up. You can pick up a card at the store and register it online, or order the card online, linking it to your checking account while you're at it, or you can download the app and pay for gas with your cell phone, all at 10¢ a gallon off the posted price, every day.
The price on the sign above, in South Dennis, has held steady for weeks, among the lowest prices in Barnstable County, as long as you pay in cash. Stations in Bourne offer the same price, but that's a long way to go for gas. You'll find this Mobil station at 452 East-West Dennis Road, which is Route 134, at the corner of Theophilis Smith Road. That sounds complicated, but you'll find it pretty easily, within a few blocks of exit 9A off the Mid-Cape Highway, which is Route 6. From the exit, turn south, toward Fresh Pond and Route 28. It'll be on your left, just past Patriot Square, right across the street from the Mid-Cape Home Center.

It may not be worthwhile to go out of your way just for a tank of cheap gas, but if you're on your way up Cape to do some errands, you might as well scope out the best bargain on gas near your destination and fill up while you're in that neighborhood.
