Q:
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.
A:
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
A:
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?
