What is 4-cycle engine oil?
Lubricating Small Engines
Oil burns up in the combustion chamber along with the fuel. A 4-cycle engine, however,
has a circulating pump that keeps oil flowing through the engine while the piston is moving
; this oil returns to the crankcase and gets recycled indefinitely.
Do 4 stroke mowers need oil?
Most mowers have what are called four-stroke engines. This means they burn straight gasoline as it comes from the service station pump, but
they also require motor oil to be added separately to the crankcase of the engine
.

it can cause the engine to choke, overheat, and cause the engine to smoke
.
Do lawn mowers need oil in the gas?
Lawn mowers that run on internal combustion engines burn gasoline as fuel, and like any engine with metal parts,
your lawn mower requires oil to lubricate the pistons and other moving parts
. The oil reduces friction between moving metal parts and protects the life of your engine.
Is there a difference between 4 cycle oil and regular oil?

What happens if you put 4-cycle gas in a 2-cycle engine?
The use of a 4-stroke oil in a 2-stroke engine can therefore cause
smoke formation and engine degradation, as well as disrupt combustion
.
Is 4 cycle oil the same as SAE 30?
It is the same oil that is used for four cycles and for regular engines
