Gulf Oil's closest audience match is the New England Patriots (0.78) — not another gas station brand in the top 10. The shape is two-peak: one cluster built around Boston sports teams and their athletes, a second anchored by Dunkin' (0.77) as a distinct regional consumer brand.

The sports-team cluster is the dominant peak. The Boston Bruins (0.76), Red Sox (0.74), and Boston Celtics (0.68) all appear in the top 10, joined by athletes Julian Edelman (0.74), David Ortiz (0.74), Vince Wilfork (0.72), and Danny Amendola (0.70) — four of the top 10 neighbors are athletes by subcategory, and three are sports teams. The second peak, Dunkin', sits just below the Patriots at 0.77 and represents a different kind of overlap: a regional quick-service brand rather than a franchise or player. Tree House Brewing Co. (0.71) rounds out the top 10 as the lone brewery, adding a craft-consumer note to an otherwise sports-and-Dunkin' structure. Mobil — the only other gas station subcategory neighbor — does not appear until well outside the top 10 in the similarity results shown here.

Gulf Oil's audience shape is defined by a concentrated New England regional identity, bridging professional sports fandom and everyday consumer habits.
