Contact

Flag us down

One address reaches us: contact@ethanolshield.org. Paper mail finds the same desk at 214 Mill Pond Rd, Suite 4, Conway, SC 29526 — though the inbox is read far more often than the mailbox.

Write when a page is wrong, a link is dead, a price looks stale, or a question about sizes and doses is not answered by the guides. We read everything and answer within a couple of working days — usually faster during the storage season, when the mail gets interesting.

What we cannot do from this address is see your order. Purchases, deliveries, returns and refunds all live at the partner storefront where the buying happened; their order page is the fast lane for anything with a tracking number on it. Questions about the formula itself — chemistry, compatibility, a label edge case — are best put to the maker, B3C Fuel Solutions, whose contacts are printed on every bottle.

If you flag us down about a mistake on the site, thank you in advance: the catalog stays sharp exactly because people write.
