What engines need mixed gas?

Many string trimmers, chain saws, polesaws, brushcutters and leaf blowers run with a 2-stroke engine. 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.

Do all 2-stroke engines require mixed gas?

Without lubrication, the metals can melt and potentially grate against each other, transferring metal to and from one another and permanently distorting them.

Which is better 2 stroke or 4-stroke?

Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. … Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.

Can you put 2 stroke fuel in a 4 stroke engine?
