1. More torque: In general, 4 stroke engines always make extra torque than 2 stroke engine at low RPM.
2. More fuel efficiency: 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes.
3. EPA Approved: As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.
4. More durability: We all know that more the engine runs, quicker it wears out. 2 stroke engines are designed for high RPM. If an engine can go for 10000 rpm before it wears out; a 4 stroke engine with 100 rpm will run for 100 minutes than the other 2 stroke engine which has a higher rpm of 500 & will run for only 20 minutes.
5. No extra addition of oil: Only the moving parts need lubrication intermediately. No extra oil or lubricant is added to fuel
