telekinesis Posted February 22, 2007 Report Share Posted February 22, 2007 Hi everyone, My Caddy recently failed inspection twice. After the first fail, I got a new exhaust, new cat. converter, and an oil change. My EGR valve and selnoid was changed this past summer. After the second fail, I failed the MEAS, the last column, by 200 points. I decided to buy the CRC Guaranteed To Pass Emissions Test Formula. The guys at Kragen says it works, but I want to come online and ask you guys before I actually use it. One thing, the back of the box says that one bottle of that stuff is good for a 16 gallon fuel tank. My cad, I believe, has a 18 gallon fuel tank. The box also says that for anyhting over 16, I should add TWO bottles. What should I do? Should I follow the instructions to the teeth or is 18 too close to 16 to warrant another bottle of that stuff. Is too much of that formula bad? Thanks, roger Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted February 22, 2007 Report Share Posted February 22, 2007 Obviously, it would be best to diagnose and repair the car. If the proper measure is one bottle for 16 gallons, can't you run the car out or nearly out of gas, add the additive, then put in 16 gallons of gas?

telekinesis Posted February 22, 2007 Author Report Share Posted February 22, 2007 Thanks Bruce for your input. The back of the box says to add it to a full tank, as opposed to add it when you're almost empty then fill it up. I suppose I can drive until I have 16 gallons left huh? =) Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted February 22, 2007 Report Share Posted February 22, 2007 Right, or just put in 16 gal then the additive. I think they are concerned that you not run the car on raw additive is all.

kev2 Posted February 22, 2007 Report Share Posted February 22, 2007 MEAS is an abrivation for measured, as compareed to ALLOWED, what part did you fail..No, Co, Hc, also knowing where you live would help.... states have different testing and then there is california.

adallak Posted February 22, 2007 Report Share Posted February 22, 2007 A common reason for which a 4.9 fails emmision test is two plugged EGR tubes inside throttle body. Make sure they are clean, if they are not, clean them with a coat hanger. Any codes storred? The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
KHE Posted February 23, 2007 Report Share Posted February 23, 2007 What section of the emission test failed? That will help point in the right direction. I doubt anything out of a can is going to cure the problem... Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
