Review: Not really useful - The engine check light disappeared for two days and came back. Before every time I reset the error code the engine check light would not come back before few days, but after using this product the it would come back next drive. Review: 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. ## Features - ADVANCED FORMULA: This product uses a powerful detergent to soften and dissolve sludge in the fuel system; removing deposits and residue. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CIPUR8 | | ASIN | B000CIPUR8 | | Best Sellers Rank | #57,145 in Automotive ( See Top 100 in Automotive ) #267 in Oil & Fluid Additives | | Brand Name | CRC | | Contains Liquid Contents? | No | | Customer Reviews | 3.9 3.9 out of 5 stars (3,135) | | Customer reviews | 3.9 3.9 out of 5 stars (3,135) | | Global Trade Identification Number | 00078254050638 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 Ounces | | Item model number | 05063 | | Product Dimensions | 20.98 x 8.99 x 5.54 cm; 0.28 g | | UPC | 078254050638 | | Unit Count | 1 Count | ## Product Details - **Brand:** CRC - **Global Trade Identification Number:** 00078254050638 - **Has liquid contents:** No - **Item weight:** 0.01 Ounces - **Unit count:** 1 Count ## Images ![05063 Guaranteed To Pass Emissions Test Formula - 12 Fl - Image 1](https://m.media-amazon.com/images/I/81n1sZdCpRL.jpg) ## Questions & Answers **Q: How do I get my money back it did not work** A: I once submitted all the required paperwork for the money back and they never sent me a dime. I did see slight lowering of some numbers but very little. Basically buy it but don’t expect to actually get a refund much less twice the amount **Q: Does this clean oxygen sensors and catalytic converter?** A: This product cleans out just about everything totally from the gas tank to the exhaust tailpipe. Severely clogged systems may require a second treatment but anyone that lets it get to that point is probably going to need a lot more than an oil change and a few spark plugs. **Q: Does it have to be done right before the test or a week before is okay?** A: i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter; if you're not passing due to HC, that is a tune up and maybe new O2 sensor... **Q: Will this help with the egg smell I get once in a while after I floor it. Doesn't stink all the time only once in a while** A: Yes, it will. The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips. This product cleans all of these areas. ## Customer Reviews ### ⭐ Not really useful *by F***I on 23 November 2020* The engine check light disappeared for two days and came back.
