Costco is the strongest pull in SpeeDee Oil Change & Auto Service's top 10, scoring 0.83 — but the more telling structural fact is that the Costco ecosystem occupies three of the top four positions: Costco Optical at 0.82 and Costco Gasoline at 0.82 form a tight cluster alongside the parent brand, pointing to one distinct audience neighborhood. A second neighborhood emerges further down, anchored by Asian-market grocery chains: 99 Ranch Market at 0.81, H Mart at 0.80, and Patel Brothers at 0.79 form a coherent bloc of general grocery stores with a culturally specific footprint. Between these two peaks sit Honda at 0.81 and Jollibee at 0.78 and L&L Hawaiian Barbecue at 0.77, which bridge the two clusters.

Notably, SpeeDee's own subcategory — Maintenance and Repair Services — does not appear among the top 10 neighbors at all. The nearest automotive entries are Car Makers: Honda at 0.81 and Infiniti at 0.77. The audience shape here is defined not by other repair shops but by a combination of warehouse retail loyalty and community-anchored grocery shopping, with fast casual dining as a secondary thread.

This two-peak structure — bulk retail on one side, specialty grocery on the other — suggests an audience that organizes its consumption around value-oriented, membership-style shopping and culturally specific food retail rather than around automotive services broadly.
