if you have a container under the seat next to your fuel that says "OIL" you have a 2 stroke scooter and can cause serious damage to the engine by running crankcase oil instead of 2 stroke engine oil. 2 stroke engines depend on burning oil to lubricate and cool themselves. 4 strokes (like your passenger car in the driveway) have 4 stroke engines with a sump (oil pan) beneath the engine that stores oil that gets lapped up by the rotation of the engine crankshaft, all that oil is used for is lubrication, nothing else. It does not get anywhere near the combustion chamber and should not burn. In a two stroke the oil is injected into the engine and burned with the fuel to create a mixture of oil and fuel.
I hope this helps you understand the differences between 2 & 4 stroke engines.
