I have used isopropyl alcohol to pass before. 1 bottle in less than a 1/4 tank of gas, but that was on a 78 Buick. I don`t know how it would work on a fuel injected car. I think there is also a shop around my area that will put a couple gallons of methanol or ethanol into old beaters that will not pass emissions tests any other way. But this is also on carb cars, I don`t know if either way would work on a EFI car.

I used denatured alcohol on my last smog test. I bought the stuff from Home Depot or Lowes, it comes in a blue and orange can. I put in a gallon of it with about 1/4 tank of gas. The car ran awesome. Just remember to get gas right after the smog. And yes, I passed
