Mixed by volume and by ratio.
If it is a 2 cycle then use only 2 cycle oil mixed with the gasoline. If it is a 4 cycle use SAE 10w30 synthetic unless the manufacture recommends a different weight.
If your talking about oil, NO you cannot. Two cycle oil is meant to be mixed with gasoline. It lubricates the internal parts and eventually ends up getting in the combustion chamber and burnt. 4 Cycle oil is menat for 4 cycle engines with no gas mixed with the oil.
If it is a 4 cycle engine, yes, it does need oil. If it is a 2 cycle the oil is mixed with the gasoline.
You will cause severe engine wear.
10w30 weight if it is a 4 cycle. Use 2 cycle oil if it is a 2 cycle.
4 cycle oil also known as 4 stroke oil. Reason: 4 cycle oil is not meant to be mixed with gasoline as the weedwacker has 2 separate lines for fuel and lubricant. Conversely 2 cycle weed wackers require 2 cycle engine oil to be mixed at a ratio of 40:1 with the gasoline.
No, absolutely not. You must use 4 cycle oil. 2 cycle oil is only used in a 2 cycle engine mixed with the fuel.
You cannot mix your own 2 cycle oil. You must purchase 2 cycle oil just like you purchase 4 cycle oil.
Any 4 cycle or automobile oil of the correct weight.
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
in place of the crankcase oil yes, mixed in the gas it shouldn't if it isn't to strong
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
