Short answer for this Costco location is "no". The truth is, Costco's Tire shop and Costco gasoline are 2 seperate departments. While most Costco locations have Tire shop, only some are also having gasoline department. In fact, I'm not aware of any Costco on Long Island nor NYC, that sell gasoline. On the other hand, most, if not all, Costco in NY have gasoline on sale. ALSO, if a Costco has gasoline on sale, it only has the "plus" and "premium" grades. They don't have the so-called "regular" grade which is the lowest grade in term of optane-value in other gas stations.
The Costco in Holbrook is the nearest one that sells gas, in Suffolk county. BJs has a gas station closer to Nassau, in Melville
