OiURecommendations
We recommend the use of Bdggs & Stratton Warranty
Certified oils for best performance. Other high-qualky de-
tergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity
for the engine. Use the chart to select the best viscosity
for the outdoor temperature range expected.

* Below 400F (40 C) the use of SAE 30 wi result in hard
starting.
** Above 800 F (270C) the use of 10W30may cause
increasedoil consumption.Check oil levelmorefrequently.
How to Check/Add OiU
1. Remove the dipstick and wipe with a c_ean cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level It should
be at the top of the full indicator on the dipstick.
4. If low, add oil slowly into the engine oil fill. Do not
overfill After adding oil, wait one minute and then
recheck the oil _evel.
5. Replace and tighten the dipstick.
FueU Recommendations
Fuem must meet these requirements:
o Clean, fresh, unleaded gasoline
o A minimum of 87 octane!87 AKI (91 RON). High alti-
tude use, see below.
o Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
CAUTmON: Do not use unapproved gasolines, such as
E85. Do not mix oil in gasoline or modify the engine to run
on alternate fuels. This will damage the engine compo-
nents and void the engine warranty°
To protect the fuel system from gum formation, mix a
fuel stabilizer into the fuel. See Storage. AHfuel is not the
same. If starting or performance problems occur, change
the fuel providers or change brands. This engine is certi-
fied to operate on gasoline. The emissions control system
for the engine is EM (Engine Modifications).
High AUtitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane/85 AKI (89 RON) gasoBine is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause de-
creased performance, increased fuel consumption, and
increased emissions. See a Craftsman Service Dealer for
high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude kit is not recommended.
