How it works
Changing oil, tips for better engine maintenance
Step 1: Getting Started
Step 2: Draining the Oil
Replace the drain plug by twisting clockwise and tightening with a box wrench or adjustable wrench. If your engine does not have an oil filter, skip this step.
Step 3: Fill With New Oil
For optimum performance, you should change the oil in your small engine after the first five hours of use and then, every 50 hours of use:
Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines.
Check oil level regularly.
Air-cooled engines burn about an ounce of oil per cylinder, per hour.
Fill to mark on dipstick. DO NOT OVERFILL
Change oil after first 5 hours of use, then after every 50 hours or at the beginning of the season.
