Gasoline Engines
FUEL RECOMMENDATIONS
These engines are certified to operate on unleaded
gasoline. Use clean, fresh, regular unleaded gasoline
with a minimum of 77 octane. Do not mix oil with
gasoline. Fresh fuel prevents gum from forming in fuel
system or on essential carburetor parts. Purchase fuel
in quantity that can be used within 30 days to assure
fuel freshness. We recommend the use of Briggs &
Stratton Gasoline Additive. (See your Authorized
Briggs & Stratton Service Dealer for Part No. 5041 or
the single-use pouch.)
In countries other than U.S.A., leaded gasoline may be
used if it is commercially available and unleaded is
unavailable.
NOTE: Some fuels, called oxygenated or reformu-
lated gasolines, are gasoline blended with
alcohols or ethers. Excessive amounts of
these blends can damage the fuel system or
cause performance problems. Do not use
gasoline which contains Methanol. If any
undesirable operating symptoms occur, use
gasoline with a lower percentage of alcohol
or ether.
Kerosene Engines
FUEL RECOMMENDATIONS
These engines are certified to operate on kerosene
and start on gasoline (petrol). Fresh fuel prevents gum
from forming in fuel system or on essential carburetor
parts. Purchase fuel in quantity that can be used within
30 days to assure fuel freshness. We do not recom-
mend the use of fuel additives in kerosene engines.
Do not mix kerosene with gasoline.
Do not use fuel additives.
Do not mix oil with kerosene or gasoline.
LUBRICATION
Use a high quality detergent oil classified “For Service
SF, SG, SH, SJ” or higher. Briggs & Stratton strongly
recommends the use of synthetic oil. If synthetic oil is
not available, Briggs & Stratton non-synthetic 30
weight oil P/N 1000005 (20 oz.) or P/N 1000028 (48
oz.) is an acceptable substitute.
No special additives should be used with recom-
mended oils.
Do not mix oil with gasoline.

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