Review: The escort passed the MOT because of this! - I put this in my 1997 Ford Escort after it failed the MOT on emissions. Filled up the tank, added this treatment, and drove it around for a few days. Took it back for the retest — passed with no issues! Not sure exactly what it did under the bonnet, but clearly it helped clean things up just enough to get through. Cheap fix compared to garage bills. Definitely recommend if you’re borderline on emissions.
Review: Worth the Money - This is really good , increases mpg , engine runs smoother ,.
