2-Cycle Oil
TRICK fuels mix well with popular brands of 2-stroke oils, including synthetic and petroleum based oils. Works well with high quality castor oils.
Compatibility
TRICK Products are compatible in all fuel systems designed to be used with gasoline.
Lead
Fuels containing lead must be used for off highway racing purposes only. Leaded fuels will damage catalytic converters and oxygen sensors when used in vehicles expressly designed for unleaded fuels. Leaded fuels deteriorate quickly when exposed to direct sunlight. Keep storage containers and gas tanks sealed tightly at all times, and place them in a cool environment away from ultra-violet light.
Octane
A numerical measure of the anti-knock properties of motor fuel. The higher the number the stronger the resistance to pre-ignition and knock. Octane is measured using two laboratory tests, the Research Octane Number test and the Motor Octane Number test. The Research test is conducted under easier conditions and usually results in a higher octane number, while the Motor test usually produces a lower number. The average of these two tests is commonly called the anti-knock index or (R+M)/2. This is the octane number used on the yellow octane sticker that you see on the pump at your local gas station. Higher octane ratings allow an engine builder to produce maximum engine power without danger of detonation.
Specific Gravity
For liquids such as fuels, specific gravity is the weight of that liquid divided by the weight of water. Knowing a fuel’s specific gravity is important when it comes to fuel systems. Changes in specific gravity can affect how both carburetors and fuel injection systems meter fuel.
