1. What is the correct fuel/oil ratio for most 2 cycle engines and products?
A 50:1 ratio with 89 Octane fuel can be used in all almost all 2-stroke equipment, provided the oil is JASO/FC and ISO-LEGD certified. JASO/FC and ISO-LEGD oil must be used with a mid-grade (89 octane) or premium gasoline in all 1997 and newer engines
2. Why should I use JASO/FC and ISO-LEGD certified oil?
ALL TWO-STROKE OILS ARE NOT EQUAL:
It is best to use mix oil that exceeds ISO LEGD standards and is JASO/FC registered (registration #001EPA646). These oil are fully compatible with all air - cooled, outdoor power equipment 2-Stroke engines at 50:1 ratio.JASO/FC and ISO-LEGD oil must be used with a mid-grade (89 octane) or premium gasoline in all 1997 and newer engines.
These oil's are made for high revving, (7000 RPM and up) air-cooled 2-stroke engines that are E.P.A. and C.A.R.B. emissions certified. Make sure the oil has a GD certification. Oils that are GA/GB/GC are of lesser quality, designed for applications such as water-cooled boat engines, low RPM lawnmower engines, or snowmobile engines. Prior to 1997, oils were not manufactured to these higher standards. Some or most of the oils were simply 30 or 40 weight 4-stroke engine oil with minimum amounts of additives.
Echo oil (by most accounts) is one of the highest quality 2-Stroke oil available.
ISO-LEGD or JASO/ FC oil will provide maximum protection against engine wear and carbon buildup.
3. Why is it important to use Premium gas?
Gasoline must be 89 octane or higher octane. Premium gasoline has greater amounts of detergents and anti-oxidizing additives to keep the engines clean. Poor gas will build-up varnish, gum and tar deposits on the piston surface and ring grooves shorten the life of the engine.
4. What are the fuel/oil storage recommendations?
Store fuel in a cool dry area in a closed container. Do not store fuel longer than 30 days. Fuel will deteriorate and lose volatility over time. Adding a fuel stabilizer can extend storage up to 90 days by forming a barrier on the surface of the gasoline and prevents contaminants from entering the fuel.
Do not allow moisture to enter the fuel container. Water is heavier than gasoline and will settle to the bottom eventually finding it’s way into your engine’s fuel tank where it could cause severe engine failure.
Use only fuel approved containers. The additives in today’s fuels can cause other than approved containers to deteriorate and contaminate fuel that is otherwise okay. Once this contaminated fuel enters an engine it tends to cause the moving parts to stick together and possibly cause serious damage to the unit.
5. How do I mix the Fuel and oil?
A 50:1 ratio with 89 Octane fuel or higher
Add half of the amount of fuel being mixed in an approved container. Add complete contents of Bottle of Premium 2-stroke engine oil (containing stabilizer) and mix thoroughly. Add the remaining amount fuel being mixed and mix thoroughly.
