Methodology & citation
Counts are computed from the same public dataset that
powers the Costco diesel map, fetched from Costco public warehouse
locator API (ecom-api.costco.com) and refreshed weekly by an automated pipeline. A
station counts as "diesel" only when Costco own service list for that warehouse
includes a diesel fuel service; "fuel station" means gas or diesel.
