An engine must also have proper lubrication. All
engines use some oil. On 4-cycle engine,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oil check plug or
dipstick opening to keep dirt from falling into
the engine when checking the oil. Always check
with the machine on a level surface. On engines
with dipstick, keep the level up to, but not over,
the FULL mark. When adding oil, allow time for
all of the oil to flow dow n the fill tube to prevent
a false full reading when the level could actually
be low and result in engine damage.

level plug, don’t be fooled onto
thinking the engine has
sufficient lubricating oil if you
can see “some” oil in the
opening – the level should
always be brought up to the
top of the fill hole.
PRIMARY MAINTENANCE
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil. A 2-cycle
engine that is mistakenly run on straight
gasoline will be ruined in less than 5
minutes! If you keep straight gasoline in
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked
to avoid mix-up.
Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA certified TC-W
oil such as Snapper’s 2-cycle engine oil.
Many of the 2-cycle engine oils on the
market today make fantastic claims, but for
the best performance and long engine life,
always use Snapper 2-cycle oil. Pre-mix the
fuel and always shake the container before
filling the tank.
Change oil at regular intervals using a high
quality oil such as Snapper’s small engine
formulated 4-cycle engine oil. Refer to the
