See full version: Is 2 cycle oil the same as 2 stroke oil
Subsequently, question is, does a 2 cycle engine need oil? Two-stroke engines require oil to be added to the fuel since the crankcase is exposed to the air/fuel mixture unlike in a 4 stroke engine. The main difference is a two-stroke engine fires once per crankshaft revolution, where as a 4 stroke engine fires every other crankshaft revolution. more
Two-stroke (two-cycle) engines require you to mix the oil with the gas in exact amounts so the oil acts as a lubricant for the crankcase, while four-stroke engines take oil and gas separately. In a 2-stroke engine, it takes one full revolution (2 stages) to complete 1 power stroke. more

Automotive engines have transformed over the years, but two main gasoline powered combustion engine designs remain: the 2-stroke and the 4-stroke. While we’re sure you’ve at least heard these terms before, do you really know the difference between them? How do they work, and which is better? Read on to learn the answers!
In order to understand how these two engines are different, you first need to become familiar with the basics.
Two-stroke engines are typically found in smaller applications such as remote-controlled cars, lawn tools, chainsaws, boat motors and dirt bikes. Four-stroke engines are found in anything from go-karts, lawnmowers and dirt bikes, right up to the typical internal combustion engine in your vehicle. It’s up to you to decide which engine you prefer, and for what purpose.
The Difference between a 2-stroke and a 4-stroke engine is how quickly this combustion cycle process occurs, based on the number of times the piston moves up and down during each cycle.
During an engine’s combustion cycle, the piston moves up and down within the cylinder. The terms “top dead center” (TDC) and “bottom dead center” (BDC) refer to the piston’s position within the cylinder. TDC is its position nearest to the valves, and BDC is its position furthest from them. A stroke is when the piston moves from TDC to BDC, or vice versa. A combustion revolution or combustion cycle is the complete process of gas and air being sucked into the piston, igniting it, and expelling the exhaust:
Two-stroke (two-cycle) engines require you to mix the oil with the gas in exact amounts so the oil acts as a lubricant for the crankcase, while four-stroke engines take oil and gas separately. In a 2-stroke engine, it takes one full revolution (2 stages) to complete 1 power stroke.
A two-stroke (or two-cycle) engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. [links]
One may also ask, can you use 2 cycle oil in a 2 stroke engine? Since all 2-cycle small engines use the same fill port for both fuel and oil, a 2-cycle oil mix is necessary for your outdoor power equipment to function properly. The Specific oil/gas ratio your small engine requires can be obtained in your Operator's Manual.
Let’s try to understand their differences in detail.
Well explained . Thank you [links]
