"Salado Sales has a brand licensed as Gate, but this bottle doesn’t list Salado Sales as the manufacturer. From our perspective, this Gate product is unlicensed."

In addition, the API says, the donut symbol is not displayed properly. "A service category must be included in the upper portion of the donut."

Weigel's

"Weigels is a licensed brand under Warren, but we wouldn’t consider the bottle you picked up as licensed because it doesn’t carry the API marks. We do, however, have some concerns about placing API SM inside a symbol. This might be considered as infringing on the API marks."

Advisory: Whereas the Gate product has a logo that looks very similar to API's, according to the American Petroleum Institute (API) the Gate Petroleum product shown is "unlicensed." In addition, the API donut is improperly displayed.

PQIA notes that if this product is manufactured by Salado Sales, it may be licensed, but mislabeled.

Date of purchase: 6-9-2010
