Fuel tanks breathe, as the liquid and air warm up they expand and push out air, that evening they cool and condense pulling in replacement air which is generally very moist and the cycle starts all over again. This happens all year long, anytime it’s warmer during the day than it is at night.
Sorry, you do not put anything in your fuel tank that has oil in it. If your going to use something, use something with PEA(Poly Ether Amine) that will actually do something good. The GM top engine cleaner does not have oil in it.
