What type of fuel do i need to use for my p/w? Does it require oil/gas mixture? Thx.

40 to 1

Two cycle engines run on a mixture of gasoline and oil. Each engine type is designed to run on a specific gas-to-oil mix ratio.
IMPORTANT: Use only oil that is labeled for use in "Two-cycle" or "Two-stroke" engines. Home Depot and other stores now have "premixed fuel" of gas and 2 cycle oil.
To mix two-cycle fuel, start by putting correct amount of oil in gas can. Then slowly add correct amount of gasoline. Do not try to mix gas and oil directly in gas tank of equipment.

IMPORTANT: Do not use any fuel that is over 30 days old. Do not mix more fuel than you are likely to use in a month. Old fuel can gum carburetors and prevent starting. Always use fresh fuel.

The chart below shows correct amount of oil per gallon that each mixing ratio requires. Expect that yours will be between 32 gas to1 oil and 50 to 1. 32:1 and 50:1 are most popular.
Ratio GAS:OIL UNITED STATES OIL per 1 U.S. GALLON Gasoline
(128 oz.) *INTERNATIONAL OIL per 1 IMPERIAL GALLON Gasoline
(160 oz.) *INTERNATIONAL OIL per 1 LITER Gasoline
(metric) 32:1 4 oz. 5 oz. 31.25 mL 40:1 3.2 oz. 4 oz. 25 mL 50:1 2.6 oz. 3.2 oz. 20 mL

Two-stroke oil with a 50:1 (Gas:Oil) mix ratio is required for the Husqvarna 125B leaf blower. Using the wrong oil or improper mixture ratio can drastically affect the performance of the leaf blower.

For almost all modern two-stroke engines, a 50-to-1 mixture is recommended. That requires about 2 1/2 oz. oil for every gallon of gasoline.

• Use only two-cycle oil for your mixture. This oil is made especially for these engines and can be purchased at gas stations, hardware stores or any other place where you buy regular motor oil.

1. Check your manual for the proper gas-and-oil mixture. For almost all modern two-stroke engines, a 50-to-1 mixture is recommended. That requires about 2 1/2 oz. oil for every gallon of gasoline.

   Pour the proper amounts of gas and oil into a fuel can. Shake the can well to mix it.

   Label your gas can with the mixture ratio. You can use the same mixture for other two-stroke engines.
   

5. 
   

   Shake your fuel can thoroughly every time you refuel. After a while, the oil will settle out of the gas, and shaking it up ensures that the oil and gas are properly mixed again before you put the fuel into your chainsaw.
   

Pump regular gas and no oil mix. Your engine has a dipstick which means its a four stroke engine.

The oil goes inside the motor. For summer use I recommend 30 weight non-detergent oil.

Change it out once a season *(Beginning would be preferred). Drain the gas out at the end of the season.

Hope this helps!

Most two stroke engines in weed eaters require a premixed fuel combination of gasoline and two cycle oil. I am assuming you have a gas model which needs a gas and oil mixture. A possible problem is the choke is turned on, and once it starts you need to move the choke to run. Another possible problem is the gas oil mixture is incorrect, and you may need to remix the fuel to the manufactures recommendation.

The header says that it is an electric saw which would only require bar oil. A 2-stroke gas engine, however, does require fuel mixed with a modern saw oil at 40:1 ratio plus bar/chain oil in it's own tank as well. Always premix the fuel and oil in a separate can and shake well even before filling the saw. Hope this helps!

The 4200 gas backpack leaf blower requires 50:1, 2 cycle oil mixed in the gasoline
