Is smoke oil the same as Deisel fuel used for automotives?

No, aviation smoke oil is not diesel fuel. <div></div><div>Some do, indeed, use diesel fuel to generate smoke, but like most of the 'home brew' alternatives to aviation smoke oil, it has its drawbacks.</div>

Its probably closer to brake fluid than diesel fuel....what size engine are you working with,,it needs to be fairly large to bother with smoke oil anyway...your OS .40 will smoke for about 10 seconds if your lucky...Rog

The Super-Dri brand smells and feels like it might have mineral oil in it. I could be wrong of course.

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...

Try ATF for your car tranny

A mix of auto trans oil and Diesel works well, have to mess around with the mix and flow rate to get the best smoke. Concrete form oil works well also, only it is getting hard to get. On smaller motors you have to regulate the flow of oil or you will flood the muffer and cool it down, less is more.

Cheers

in our planes (full size planes) we use concrete mold release agent.  We have found that it works extremely well. <input id="gwProxy" type="hidden"><!Session data></input><input onclick="jsCall();" id="jsProxy" type="hidden"/><div id="refHTML"></div>

WOW! you're allowed to do that? -1 for the environment ... burn baby burn

IMO, there's 2 kinds of smoke oil : Super Dri, and the ones that don't work very well.<div>
</div><div>ATF fluid has a couple of drawbacks, imo.  First, its smoke is not as "dense white" to me.  Second, it attacks covering far more than ASO does.</div><div>
</div><div>Concrete mold release, as mentioned above, is not the greatest environmentally, and from what I've seen, is now even MORE expensive ($45 a gallon on ebay, but I didn't search very hard) than ASO.  Of course, bowers says he's using it in 1:1 applications, so maybe there's a cheaper source in large quantities or something.</div><div>
</div><div>Diesel will certainly work...but again, the smoke isn't as thick, and it takes a LOT of it to get large plumes...more than you care to carry around in an airplane, I'd wager.</div><div>
</div><div>Finally, for me at least, ASO is a known entity.  In the video below, there's no "heating coils", no fancy "smoke muffler", not even a fancy "smoke pump" that's somehow slaved to the throttle.  None of that.  It's a $9 windshield washer pump dumping ASO into stock DLE mufflers.  Period.</div><div>
</div><div>All ASO does is produce thick, dense, white smoke...every time...without messing with things.</div><div>

Check out the link below, freedom form release $57.82 for a 5 gallon pail. organic based. I find it funny that it is environmentally friendlier to burn oil or deisel or super dry than it is to burn form release agent. Garanteed none of it is GOOD for the environment, but if that was the main concern we would all go electric and walk to the feild.

Shhhhhhhhhhhhhhh!

The "green police" will hear that then smoke will be banned.

we use transformer oil in our 802 also we may try the form oil next time, we get it in 55 gallon drums though, some ag pilots do use automatic tranny fluid for the smoker too, the transformer oil somkes very well but again we are pumping it into the exhaust of a 1300shp turbine too, dunno about a model but im going to try it on one when i get an airplane built that i want smoke on., a friend of mine he flys a sukhoi 26 (full size) and actually uses the super dri model smoke for his airshow routine,
