Use exactly what the manufacture of the equipment you are using recommends. I know that Echo recommends 89 octane in their 2 cycle engines. Some may recommend 87. Read the owners manual that came with the equipment.
A four cycle engine does not use a gas/oil mixture. The oil is in the crankcase and the gas goes in the gas tank. If you put oil in the gas on a 4 cycle engine it will run poorly and smoke a lot.
You may use any quality TCW3 rated, 2 cycle oil.
No - 2 cycle oil is the only oil you should use in a 2 cycle motor. Because 2 cycle oil is designed to mix with the gas and lube the motor. Your "truck oil" is not the 4 cycle oil will not mix it is designed to just lube in the crank case.
Electric chainsaws do not use gas !! They do however use oil on the chain.
Answerif it,s a 2 cycle mix gas 50 parts to 1 part oil,if it,s a 4 cycle . none, gas treatments will cause a lawn mower engine to over heat,I have small lawn equipment that used gas/oil ratio, I use a gas treatment in mower to keep from getting gunky over winter months, should I use a gas treatment for equipment that uses gas/oil ratio
No, you can not use engine oil in place of two cycle oil.
2 cycle oil is meant to be used when your engine requires fuel/oil mix gas. If you have a dip stick for oil, your machine doesn't use mixed gas/oil.
2 Cycle oil does not "burn" so that it leave behind a oil film when the gas burns off. you may see the words "ash-less" on some brands of 2 cycle oil. 4 cycle oil will burn and turn sticky, gumming up your engine.
2 cycle oil. mix 2.6 ounces per gallon of gas
2 stroke oil
Use a quality 2 cycle oil only. I recommend you use a synthetic 2 stroke oil.
The type of oil you use depends on the type of engine you have. A good way to tell if it is a two-cycle or 4-cycle is to look for an oil filler cap - usually a screw-in cap about 1 to 1-1/2 inches in diameter. If the engine has an oil filler cap, it is a 4-cycle engine and you add 30-weight oil through the filler hole. If there is no oil cap, then the engine is a 2-cycle and you must mix 2-cycle oil with the gasoline. If it is a 2 cycle be sure and use only 2 cycle oil in the mix.
