G2P Fuel System treatment

has anyone ever used this stuff called Guaranteed To Pass (G2P)? its this fuel additive thats supposed to help pass smog guaranteed. i failed smog already and just want to know if this stuff will help me pass or if its just bs.

you can try it, you may get lucky. but if that doesnt work make sure your tuneup components are in good shape.... and the one that gets a lot of cars to pass... change your oil, then drive it down the highway for about 30 miles. reason being, hydrocarbons from cylinder blow-by are in the oil, since every car burns even tiny amounts of oil sometimes this will cause the car to fail a smog test

Well, i used G2P and still failed. i actually did way worse than i did without it. what a waste of seven bucks man. how do u know when its time for new catalytic converters or O2 sensors?
