I filled up my Hyundai SUV and neglected to replace the gas cap before running it through a very powerful car wash. I feel certain water entered the gas tank. The car is performing OK for now, but need to add something to it to be safe. A mechanic friend recommended the B-12 additive. I wanted to make sure that was the one that I should add to be safe.

B-12 (#0116, #0112 and #1112) disperses water, causing it to be broken into smaller globules that can be carried out of the tank and burned through the combustion system or trapped in the fuel filter. The small amount of water that is carried through to combustion actually aids in the removal of carbon build ups in the combustion area. If larger amounts of water are present such that the filter plugs readily, remove the filter and spray B-12 through from the outlet side to flush out contaminants. Replace the filter and continue to repeat the process until the water is removed and then replace the used filter with a new one.
