What is not counterfeited these days? Really, I do wonder. I usually do not hear much about fake petroleum. They are not a lot of fakes, as oil is really cheap. If oil trades at $100 a barrel, and a barrel holds 53 gallons, you can see how cheap a single gallon is.
When I buy oil for my car, I usually open it and start pouring it into my engine. I don’t inspect it, and have really not seen anyone either. If I bought counterfeit oil and put it in my car, it could destroy the engine, and it will cost me a lot of money and time to remove the fake oil from the car.
