LUBRICATION
Oil has four purposes. It cools, cleans, seals and
lubricates. Briggs & Stratton engines are lubricated with
a gear driven splash oil slinger or a connecting rod
dipper.

Oil Recommendations
Use a high quality detergent oil classified "For Service
SC, SD, SE or MS." Detergent oils keep the engine
cleaner and retard the formation of gum and varnish
deposits. Nothing should be added to the recommended
oil.
RECOMMENDED SAE VISCOSITY GRADES
*If not available, a synthetic oil may be used having 5W-
20, 5W-30 or 5W-40 viscosity.
Change Oil (Crankcase)
Change oil after first 5 hours of operation. Thereafter
change oil every 25 hours of operation; more often under
dirty operating conditions. Remove oil drain plug,
Fig. 1, Ill. 1 or 2 and drain oil while engine is warm.
Replace drain plug. Remove oil fill plug or cap and refill
with new oil of proper grade. Replace oil fill plug or cap.
Check oil level regularly – at least after five hours of
operation.
BE SURE OIL LEVEL IS MAINTAINED.

Check Oil (6 to 1 Gear Reduction Models)
6, 8, 60000, 80000, 100000, 130000
Remove the oil plug in lower half of gear cover every 100
hours of operation to check the oil level. Fig. 2.
Add SAE 10W-30 oil at upper oil fill plug until oil runs out
of lower hole. Replace both plugs.
NOTE: Filler plug has vent hole and must be placed in
top opening.
