Service SF, SG, SH, SJ" or higher, such as Briggs &
Stratton SAE 30, Part Number 100091 (3.2oz) or
Briggs & Stratton Synthetic Oil, Part Number
100074.
• Do not use special additives.
• Choose a viscosity according to the table below.

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
** Use of SAE 30 oil below 50° F (10° C) will result in hard
starting and possible engine damage due to inadequate
lubrication.

• Check level daily, or after every eight (8) hours of
use.
