Oil Recommendations
Oil has four purposes. It cools, cleans, seals and lu-
bricates. During normal operation, small particles of
metal from the cylinder walls, pistons, bearings and
combustion deposits contaminate the oil. Dust par-
ticles from the air also contaminate the oil, forming
an abrasive mixture that can wear internal engine
parts if the oil is not changed regularly. Fresh oil as-
sists in cooling. Old oil gradually thickens and loses
its cooling ability and its lubricating qualities.
Briggs & Stratton OHV V-Twin engines are lubri-
cated with a gear-driven oil pump.
Use a high quality detergent oil classified “For Ser-
vice SJ or HIGHER” such as Briggs & Stratton 30
weight oil part #100005 or #100028. Detergent oils
keep the engine cleaner and retard the formation of
gum and varnish deposits. Do not use additives with
recommended oils.

Air cooled engines run hotter than automotive
engines. Use of multi-viscosity oils (10W-30,
etc.) in ambient temperatures above 40 F
(4C) will result in high oil consumption. If
multi-viscosity oil is used, check oil level more
frequently to prevent any possible engine
damage due to lack of lubrication.
** SAE 30 oil, if used in ambient temperatures
below 40 F (4 C) will result in hard starting
and possible engine damage due to inade-
quate lubrication.
Synthetic oil meeting ILSAC GF-2, API certifi-
cation mark and API service symbol with “SJ/
CF ENERGY CONSERVING” rating or higher,
is an acceptable oil at all temperatures.
NOTE: Use of synthetic oil does not alter
the required oil change intervals.
