Check out this fake can and the others for sale. Ounce is even spelled wrong.

Yah I saw these this morning. When I saw the first one I thought, hmmm? Never seen that before. That's interesting. Then I saw the second, and then the third. I figured something seems fishy!

It can be reported as a fake/counterfeit by using the "Copyright and Trademark" listing..

Then select the "Counterfeit item or Authenticity disclaimer"...

Select "Counterfeit, fake or replica items"....

One has to be very brief in the description; I noted the misspelling of "ounce". There is no way an Oil Company would allow such an item as a "sample" with their name on it, as Keith noted...
