Vehicles here 15 years or older don't have an emission test--but they must pass a "visual" test,if the engine smokes pretty good,they can refuse to pass it for an inspection sticker..
A used car dealer guy I know uses "stop-smoke" oil sold at parts stores to get clunkers that smoke some to pass inspection..stuff is clear as water,and thick,it does work too--one customer of his took a car he bought that had that oil in it to my friends shop for an oil change 3000 miles later--he put 5W-30 in it ,which was the viscosity recommended on the oil filler cap,it smoked so bad the owner got pulled over on his way home and got a "verbal warning"...
He came back the next day asking WTF happened to his car,my friend said "you had that "smoke stop" oil in it,and I put back what belonged in it"...he ended up buying 5 quarts of the smoke stop oil and he changed the oil again with it and the smoking stopped..
Now the guy is pissed at the place he bought the car from!..
