2-Cycle Engines & Fuel Treatment FT-10™
2-cycle (2-stroke) engines are most commonly used in lightweight, small applications such as outboard engines, chainsaws, leaf blowers, weed trimmers, and other outdoor power equipment.
The 2-cycle engine completes a power cycle in just two piston strokes per crankshaft revolution (vs. 4 strokes in a 4-cycle engine). They can generate a lot of power for such a small package. Because these small engines use a single fill port for both engine oil and fuel, a mixture of fuel and 2-cycle oil is added to the fuel tank. Proper mixture is important for continuously lubricating the engine’s moving parts, i.e., piston, connecting rods, and crankshaft. By including Fuel Treatment FT-10™ in the mixture, you will not only improve critical lubrication, but keep the fuel injectors and pump lubricated and clean as well.
Determining the Oil Mixture
Check your Operator’s Manual for the oil-to-fuel ratio needed for your 2-cycle engine. Often the ratio can be found on the engine label.
Pour the required amount of 2-cycle oil into an approved fuel can. Never mix the fuel and oil in the engine’s fuel tank.
Add the correct dosage of Fuel Treatment FT-10™ (see the chart below).
Add the specified amount of fuel.
Stir or shake the container to thoroughly blend the mixture.
We recommend adding 2-oz. of Fuel Treatment FT-10™ to every 5 gallons of gasoline. For high-performance racing engines, add 4-oz. of FT-10™ to every 5 gallons of fuel. The chart below may be helpful:
REMINDER! Fuel Treatment FT-10™ is NOT a substitute for the 2-cycle oil – keep using the 2-cycle oil in the fuel mixture per the engine manufacturer’s instructions.
FAQ: 2-Cycle Engine Treatments
Why only 2 oz. of FT-10™ per 5 gallons of fuel rather than the standard automobile engine dosage (2 oz per 10 gallons of fuel)? Because 2-cycle engine dynamics are very different – their parameters are more severe than water cooled/oil lubricated engines. Years of usage has revealed the best results in performance, longevity, and economy are with the 2 oz per 5-gallon fuel ratio.
Can I use both Metal Treatment MT-10® and Fuel Treatment FT-10™ in my 2-cycle engine? Sure, but it’s not necessary. Fuel Treatment FT-10™ has just the right amount of MT-10® pre-blended in its formula for optimized performance and critical engine lubrication. However, if you do choose to use MT-10®, don’t use too much! Smoking and spark plug fouling can occur from too much oil in the fuel. Recommended dosage: Blend 1 oz. (30 ml) of MT-10® with 8 oz. of 2-cycle oil. Blend the oil mixture with the fuel and add Fuel Treatment FT-10™ as described above.
