Beware of Contaminated Gas Additives

During the week of November 20 to 26, 2022, I had gone to Walmart in Rohnert Park, Ca. to purchase Lucas Deep Clean Fuel System Cleaner. I noticed that a total of two bottles had been tampered with, the seals had been broken, and the fluid replaced with paint thinner or mineral spirits. I told several managers and left it up to them to deal with. What moron would do such a thing? Paint thinner can damage a fuel system, engine components, seals, cause rust and corrosion of the inside of the tank. This can cause thousands of dollars to fix.
