I recently did not pass my emissions inspection... by a small margin..



I purchased Emission Pass Liquid and followed the directions... it said
to add to a full tank of gas and then another bottle when the gas was
almost empty before a fill up............ I did and it passed the
emissions inspection......... I am just wondering what did it do, how
did it work...



Any other tips... would be appreciated as well.................



Thanks so much and god bless.....................

the additive is typically alcohol that will burn with 0 emmisions and will lean out the fuel system a very very small amount and that is why it worked.

your engine will not compensate for more than that small bottle.so 2,3,10 bottles will make that engine run bad.
