Joseph, Yes, certain brands are being "Faked"... I collect Veedol/Tydol/Flying A... There are a number of Sellers on Ebay; selling fake Tydol and Flying A Cans; thankfully they are not close to being correct in color and in some instances, the graphics are way off...

My advise, is before you buy any cans. You look into purchasing a couple of the Oil Can "Guides"... Amazon usually has some used ones for a pretty fair prices. Ebay occasionally has a few and occasionally Oldgas Members will sell one's they have... Better to wait until you get some knowledge before buying some fakes and/or marginal conditioned cans... But, that is just my opinion....
