Zaxby's is the single strongest signal in Express Oil Change's top 10 — a fast casual dining chain sitting at 0.90, well above every other neighbor. That gap is the defining structural feature of this data.
The shape is a spike, and the rest of the top 10 confirms it: scores fall from 0.90 down to 0.80 across nine other neighbors, none of which share Express Oil Change's own subcategory of Maintenance and Repair Services — except Joe Hudson's Collision Center, which appears just outside the top 10 at position 16 (0.80). Within the top 10 proper, the neighbor set is almost entirely cross-kind. Inky Johnson (0.84, Athletes) and Waffle House (0.83, Casual Dining) are the next closest, followed by Booger McFarland (0.82, Athletes) and The Gospel Coalition (0.82, Blogs). Tallying the subcategories across all ten: Athletes appear three times (Inky Johnson, Booger McFarland, and Joe Burrow at 0.80), dining brands appear twice (Waffle House and Shoe Station is Footwear — correcting: dining is Waffle House and Zaxby's), and the remainder span Blogs, Sporting Events, TV Shows, Journalists, and Footwear. The two most prominent threads are college football–adjacent figures and Southern dining brands — a combination that points to a distinctly regional audience profile.
The overall picture is an automotive service brand whose audience shape is defined less by automotive peers than by college football media, Southern restaurant chains, and faith-oriented content — a tight regional and cultural cluster anchored hard by one fast casual outlier at the top.
