Smoke Fluid - How Much Is Enough?

I usually put 15 drops in my big engines when I am done running for the day or night.The fluid slakes in good and the units smoke great the next day without having to blow in them every 16 seconds.Nick

I have put up to 20 drops with no problem. I let the smoke unit cool down and put fluid in after I power down for the night or let it cool down before another fill up on a longer running session. 

I have never heard anything but drops for the recommended fluid measurements? No matter what drop size I get, I follow the 10-15 drops method (or 15-20 for a new engine). After running for a few minutes if it isn't smoking well I add another 10 drops or so. I have a needle bottle I use, so I get the fairly small drops as well.

This has worked for me for at least 3 years with no problems unless the engine's smoke unit had problems. Which just happened for the first time a couple weeks ago. After a little fiddling, some great assistance from the OGR forum members here and loading a new PS3 file, all is better now.

Well it doesn't matter to me because I have no way of measuring the size of my drops in mms.

It depends on the unit. Not all reserve chambers are identical, so its not an exact measurement. Even the denseness of packing would cause variance of a few drops let alone size of the drops

 I do it this way, dry (like rebuilt, or not used for a year or more) resting on paper towel, 5-10 drops wait 5-10 min. check towel, test. repeat till it leaks or stops smoking from too much fluid. Once leaks settle run it till it smokes again, then stops smoking. Repeating with measured drops give you a "wet" measurement. For me, this varies from 4-5 on a PW General to 1 1/2 whole droppers full of fluid.  .
