Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality deter-
gent 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 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil
consumption. Check oil level more frequently.
How To Check/Add Oil
Before adding or checking the oil
Place engine level.
Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 1) and wipe with a clean
cloth.
NOTE: On some models, the dipstick is accessible through
an opening behind the operator seat.
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 (B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not
overfill. After adding oil, wait one minute and then
recheck the oil level.
5. Replace and tighten the dipstick.
