Pass Again
Size: 1 Count (Pack of 1)
This product never fails (no pun intended), I have been using this for the last 10 years my car has never failed a smog test. I highly recommend this and that you use it correctly. You will not be disappointed.

Really Helps-Especially for Star Station Tests-Haven’t Failed Since Using in Two Older Vehicles
Size: 1 Count (Pack of 1)
Ever since the new CA State mandate that older cars and trucks have to go to a Star Emissions Station for their smog check I have become very familiar with Guaranteed to Pass. The first year of getting smogged under the new regulations my 1995 truck barely failed. It’s a tougher series of tests and it really sucks to have to pay more for a smog test that is designed to get older cars and trucks off the road that would normally pass a regular smog check. It came at a bad time, having just been laid off and losing my health insurance and income and trying to figure how to come up with money for truck repairs to get my registration renewed so I could be a viable job candidate in the really bad job market of a few years back (and still today, may I add.) But that is a whole other issue that gets my blood boiling. So back to my experience with Guaranteed to Pass. My 1995 Ford Truck barely failed and I mean barely according to the emission numbers so I had the manifold cleaned out, used premium gas for a tank and added Guaranteed to Pass. Having two gas tanks was handy as I could switch the tank to a fresh tank without the remainder of the additive in it for the retest. It passed with flying colors.
So for our other older 1993 mini-van and the truck in the few successive years since I always run the premium gas with Guaranteed to Pass in the tanks before the smog check. We’ve had the van and truck tested 3-4 times combined since and they pass every time. So I’m sold on Guaranteed to Pass and will vouch for it.
