SMOKE FLUID/OIL

The very best oil one can get is manufactured by TEXACO OIL CORPORATION under the specification "CORVUS OIL 13", approximately $2.00 per gallon.

This type of oil is light and does not need any dilution. TRY IT. Your injection nozzle should be as close as possible to the exhaust port of the engine. You may have to increase or decrease your supply line/nozzle to achieve volume/pressure and with the right amount of temperature you will get good lasting smoke.
