Steps to Better Engine Maintenance

For optimum performance, you should change the oil in your small engine at least once per season, or every 25 hour of use.

Step 1 - Getting Started:
Start the engine and run it until it is warm. Stop the engine. WARNING: Be sure to disconnect the spark plug wire, and secure it away from the spark plug to prevent accidental starting. Clean around the oil fill and drain plug area to prevent dirt and debris from falling into the crankcase (see photo at right). Remove the dipstick, if equipped.

Step 2 - Draining the Oil:
Tilt the mower deck with the air filter or spark plug side up, and position some newspaper and an oil pan or jug beneath the mower. Use a 3/8" drive socket wrench and extension (no socket) to turn the plug counter clockwise (see photo at right), allowing the old oil to drain. If the plug also serves as a fill cap (normally yellow or white in color), it may have two prongs so you can loosen it by hand or with a screwdriver or hex key for additional torque.

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 - Engines with Oil Filters:Oil Change Engines with Oil Filters
If your engine has an oil filter, replace it at least once per season.

Replace the oil filter by twisting counterclockwise on the body, using a filter wrench or pipe wrench.

Examine the sealing surface on the oil filter adapter for debris or gasket material. Clean if necessary.

Lightly oil the filter gasket with clean engine oil. Install a new filter, screwing in by hand until the gasket contacts the filter adapter (see photo at right). Tighten the filter an additional 1/2 to 3/4 turn.

Step 4 - Fill with New Oil:Oil Plug
Pour in the correct amount and approved type of oil for your engine, based on your operator’s manual. If you have two oil fill plugs (normally yellow or white in color) on each side of the engine, either one can be used to fill the engine with oil to the correct level. Please DO NOT fill the engine with oil without using the correct measuring device as illustrated in your operator’s manual.

Oil Recommendations:
To optimize engine performance, use Warranty Certified Briggs & Stratton Small Engine Oil. Briggs & Stratton offers a Synthetic 5W-30 oil that provides the best protection at all temperatures as well as improved starting with less oil consumption.

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.

Reduced Emissions

Briggs & Stratton engines featuring ECO PLUS™ Emissions Reducing Technology deliver significantly improved environmental performance.

ECO PLUS engines offer reduced evaporative emissions performance by up to 59% compared to engines which do not feature ECO PLUS.
