Q: How do I mix gas and oil? A: Mix 3.2 ounces of Poulan 2-cycle air cooled engine oil to one gallon of fresh unleaded gasoline to obtain the recommended 40:1 fuel to oil ratio.
Poulan suggests a ratio of 40 parts fuel to 1 part oil.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
A: The fuel-oil mixture ratio is 40:1. You can obtain this ratio by mixing 3.2 oz. of two cycle air cooled engine oil with one gallon of regular gas.
You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you`re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture.
Poulan/WEED EATER brand synthetic oil is recommended. Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 ounces (95 ml) of oil with 1 gallon (4 liters) of unleaded gasoline.
A 40:1 ratio is recommended for this particular model. To obtain the correct mixture, pour 3.2 ounces (95 ml) of 2-cycle synthetic oil into one gallon (4 liters) of fresh unleaded gasoline.
Mix at 50:1 (20mls oil per 1 litre fuel) when you`re using STIHL 2-Stroke oil.
For two-cycle handheld equipment manufactured after 2002: Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil.
This is why STIHL recommends always using fresh fuel or specially formulated fuel mixes like STIHL MotoMix® in your equipment. STIHL MotoMix® is a high-grade, high-octane, ethanol-free premixed fuel containing STIHL HP Ultra synthetic oil.
All STIHL gasoline-powered equipment uses a 50:1 gas and oil mixture.
All Weed Eater brand two-cycle gas trimmers use a 40:1 ratio of gas to oil. That`s equal to 3.2 ounces of oil to 1 gallon of regular gas. The gas should be 87 octane with no more than 10 percent alcohol. The oil must be formulated for two-cycle engines.
50 to1 means 50 parts of gas to 1 part of oil. So the 40 to 1 mixture is more oily and provides better lubrication for your piston rings. The downside is it will foul out your spark plug sooner, but that`s no big deal because it`s simple to pull the plug out and clean it and stick it back in.
If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
What is the ratio for 2-stroke fuel mix? Most modern petrol garden machinery requires a 50:1 ratio mix of petrol to oil. This means for every 1 litre of petrol you must mix 20ml of oil.
100:1 – Mix 50ml of oil per 5ltrs of fuel
Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.
The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
Use a 32:1 gasoline to oil ratio. One gallon of gasoline combined with 4 oz of two-cycle engine oil.
STIHL recommends that customers use a minimum of 89 octane fuel. If a customer chooses to use a 91 or 93 octane fuel, no damage to the engine will result. However, using an 87 octane fuel could lead to serious engine damage.
If you are treating 1 gallon of clean unleaded gasoline, a 50:1 ration translates to 2.5 ounces of two-cycle oil, while preparing a 40:1 blend calls for 3 ounces of oil. Use the same type of container designed for gasoline storage, measure correctly and mix the fuel completely before filling your chain saw.
The T-00745 Synthetic 2-Cycle Fuel Mix, 2.6 oz. is 50:1 synthetic fuel mix with fuel stabilizer for improved engine performance.
Fuel tank capacity: 0.59l. Weight: 5.2 kg.
STIHL currently recommends that you do not store or use fuel older than 60 days, and preferably no longer than 30 days, even with a stabilizer. Read more about storing your outdoor power equipment.
Your chainsaw will need an unleaded, mid-grade gasoline with an octane rating of at least 89. This is one of the few times you`ll want to spend the money for premium gas. Unlike other small engines, most chainsaws us a high-performance engine. If the octane rating is not at 89, you risk knocking your engine.
