Don’t dump a full bottle of PI in gas tank

I'm sure for a vehicle a full bottle will be fine, and will most likely provide a certain level of improvement, based on previous maintenance regime. But overall this reminds me of that one time when I put a gallon of Marvel Mystery Oil in a 30 gal gas tank of a 1995 Chevy Tahoe. Same result really. Had to replace spark plugs because the sputtering was still there 3 full tanks of gas only later.
