The super-dri gives a great smoke plume in bigger (gasser) engines, even a 1.2 4stroke is barely big enough for smoke though, the plume lasts 12 seconds then mufflers too cool to make smoke.  Diesel is definately NOT the same, I've run diesel in my yak (100cc) and it doesn't smoke near so good as the super-dri.  Just got a 5gal bucket of the new 'Robart smoke fluid' will see how it does in the next wk or so...
Just out of morbid curiosity might try water one of these days, see if it makes steam or something... but doubt anything can come close to the super-dri plume...
