Where is my Briggs and Stratton model number?

How Do I Identify a Briggs & Stratton Engine? The Model, Type and Code numbers, stamped directly into the engine, are used to identify our engines. Engines used in lawn mower applications usually have the model numbers stamped directly into the blower housing, muffler heat shield, or a few inches above the spark plug.

When did Briggs and Stratton go out of business?

In 2019, Briggs & Stratton announced they would be closing their engine factory in Murray, Kentucky, with production being moved to their Poplar Bluff, Missouri facility. On July 20, 2020, Briggs & Stratton filed for Chapter 11 bankruptcy. KPS Capital Partners purchased a majority of the company stake for $550 million.

What type of oil does a Briggs and Stratton lawn mower take?

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.

What fuel does my Briggs and Stratton use?

All Briggs & Stratton engines can use up to, and including, 10% ethanol petrol. Always use clean, fresh, unleaded petrol with an octane rating of at least 77 for side-valve engines or at least 85 for overhead-valve engines.
