OEM brand risk
An informal oil buyer at a branded pit is a brand-risk event if that oil is dumped or mislabelled. Treat used oil like parts: serialise the vendor.
Throughput math
Oil-change bays produce predictable litres. That predictability is what recyclers pay for. Publish monthly volume on a BioTradX listing instead of waiting for a collector to guess.
Multi-brand independent workshops
Same SOP, smaller lots. Weekly van pickup beats waiting for a tanker. Still demand authorisation documents.
