Oil
Oil Capacity
Engine holds approximately 1-1/2 quarts (48 ounces or
1.4 liters) when changing oil and filter.
Oil Recommendation
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 unavailable, Briggs & Stratton
non-synthetic 30 weight oil P/N 1000005 (20 oz.) or
P/N 1000028 (48 oz.) is an acceptable substitute.
Do not use special additives.
Choose a viscosity according to the table below.
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.

SAE Viscosity Grades
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.
** SAE 30 oil, if used below 40° F (4° C), will
result in hard starting and possible engine
bore damage due to inadequate lubrication.
Checking and Adding Oil
Check oil level before starting the engine.
Keep oil level at FULL. Do not overfill.
Check level daily, or after every eight (8) hours.
Oil Fill
1. Place engine level and clean around oil fill and
dipstick.
2. Remove dipstick and wipe with clean cloth.
3. Tighten dipstick down. Remove and check oil
level.
4. Remove oil fill cap. Pour oil slowly. First add 1 qt
(32 oz or 1 liter). Start and run engine at idle for
30 seconds. Shut off engine and wait 30 seconds.
Then add more oil slowly to bring level to FULL
mark on dipstick.
5. Fill to FULL mark on dipstick. Recheck.

6. Tighten dipstick firmly.
Oil Pressure Switch
If engine is equipped with oil pressure switch, the
switch will either activate a warning device or stop the
engine when the engine runs low on oil. (Read the
operating instructions supplied by equipment
manufacturer to determine how your engine is
equipped.)
