Must two-stroke engines be lubricated?

Question

DentroTest · Accepted Answer

All engines need a lubrication system due to the continuous friction of their internal parts. In two-stroke engines, this lubrication is done by mixing a certain amount of oil directly with the fuel. This mixture can be done manually when refueling or through independent tanks that do it automatically before entering the engine.
