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.
Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil.
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.
Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. Poulan/WEED EATER brand synthetic oil is recommended. Mix gasoline and oil at a ratio of 40:1.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
Mixing Your Fuel
Your strimmer runs off a mix of semi-synthetic 2-stroke oil and unleaded petrol (40:1). Our petrol tools come with a measuring jug with guide lines. Find the side marked 40:1, add your petrol to the first line and your 2-stroke oil to the second.
Two-stroke (or 2-cycle) engines require a mixture of fuel and oil be added to the fuel tank. This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
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 fuel / oil ratio of 50:1 is recommended for all Husqvarna 2-stroke products.
This ratio indicates how much fresh, regular unleaded gasoline (containing no more than 10% ethanol) to mix with how much oil. For all Remington 2-cycle products, the ratio is 40:1. This means you`ll want to add 3.2 oz of oil to every gallon of gasoline.
What happens if the mixing ratios in a 2 stroke engine are incorrect? If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine, blow excessive smoke which is particularly bad for the environment and may (with time) cause the engine to stop operating correctly.
