Phillips 66 Aviation Smoke Oil is a paraffin based, high quality fluid for use in both piston engine and turbine engine smoke systems. Phillips 66 Aviation Smoke oil can be readily vaporized due to its low viscosity. It also has outstanding low temperature properties that allows it to flow and burn easily in colder temperatures. Of coarse, this is the smoke oil of choice for the Phillips 66 Aerostars Aerobatic team but it is also approved for use by the U.S. Navy Blue Angels.
