Assessing stations for ethanol blends: what to document
Component-level inventory, manufacturer documentation and traceable decisions without assuming compatibility by brand or year.

In this article
A useful assessment identifies each component and finds the documentation that applies to that unit. Brand, station age and a generic parts list do not establish compatibility.
Before setting dates or budgets
The ethanol-blend schedule is regulatory information that can change. See the Panama E10 status record, which lists its sources and review date, and recheck official documents before recommending a date or purchase.
Inventory before conclusions
Record manufacturer, model, product number, configuration and material for tanks, lines, pumps, hoses, nozzles, filters, meters, seals and monitoring systems. Station age or dispenser brand does not prove compatibility.
Exact documentation
Locate the document that applies to each unit and blend. Catalogs from OPW, documentation from Wayne/Dover Fueling Solutions and manuals from Gilbarco show that compatibility is stated by product and configuration, not by a general brand rule.
Decision matrix
Classify each item as confirmed, incompatible or pending evidence. “Pending” is the correct result when the nameplate, revision or listing is insufficient. Only then should the team decide whether to keep, inspect, replace or consult the manufacturer.
Use this template for the installed equipment. Fields without documentation remain pending; the table does not establish compatibility or authorize a purchase.
| Component | Part number and revision | Document and edition | Specified blend | Decision |
|---|---|---|---|---|
| Tank | To record | To collect | To confirm | Pending |
| Hose | To record | To collect | To confirm | Pending |
| Filter | To record | To collect | To confirm | Pending |
What an assessment should not promise
It should not invent a degradation period, guarantee future tightness or assume one standard retrofit fits every model. The useful deliverable is a traceable matrix showing the source used and the gaps that remain open.
