OIL CAPACITY

Engine holds approximately 3 ounces (90 ml).
TYPE OF OIL TO USE
• Use a high quality detergent oil classified "For Service
SF, SG, SH, SJ" or higher, such as Briggs & Stratton
SAE 30, Part Number 100005 (20 oz) or Briggs &
Stratton Synthetic Oil, Part Number 100074.
• Do not use special additives.
Note: Synthetic oil meeting ILSAC GF-2, API certifica-
tion 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.

ADDING OIL

CAUTION
: KEEP ENGINE LEVEL
Engine must be level, with oil fill facing up, to check
oil. If engine is not level, dipstick reading will not be
accurate. This will lead to possible over or under
filling causing damage to the engine.
• Check oil level before starting the engine.
• Check oil level before every use.
• Keep oil level at FULL.
• DO NOT overfill, use oil measure cup for filling.
• Add only 1 oz. – 0.5 oz. of oil at a time.

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
CAUTION:
Air cooled engines run hotter than
automotive engines. The use of non-synthetic
multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40° F (4° C) will result in higher
than normal oil consumption. When using a
multi-viscosity oil, check oil level more frequently.
* CAUTION:
Synthetic oil must be used when
operating engine under 40° F (4° C) or engine
damage will occur.
** CAUTION:
SAE 30 oil, if used below 50° F
(10° C), will result in hard starting and possible
engine bore damage
lubrication.
