FUEL & OIL RECOMMENDATIONS
Fuel Recommendations
Gasoline Engines
•
Use clean, fresh regular unleaded gasoline with a
minimum of
85 octane
. Fresh fuel prevents gum
from forming in the fuel system or on essential
carburetor parts. Purchase fuel in a quantity that
can be used within 30 days.
•
Do not use gasoline containing Methanol.
•
Do not mix oil with gasoline.
•
For engine protection use Briggs & Stratton Fuel
Stabilizer
#5041
or single use pouch
#5058
available from your Authorized Briggs & Stratton
Dealer.
CAUTION:
Some fuel, called “oxygenated” or
“reformulated” gasoline, is gasoline blended
with alcohol or ether. Excessive amounts of
these blends can damage the fuel system or
cause performance problems. If any undesir-
able operating symptoms occur, use gasoline
with a lower percentage of alcohol or ether.

Replace inline fuel filter yearly or every
100 hours
,
whichever occurs first. Replace filter if dirt or water
are present. See illustrated parts list for correct
fuel filter.
