What oil does a brigg and stratton 190cc lawn mower engine use?

Briggs & Stratton recommend using SAE 30 weight oil in their 190cc lawn mower engines. You could also use a 10W-30 weight oil if the temperature in your area is consistently above 40°F.

Here are some additional tips for choosing the right oil for your Briggs & Stratton lawn mower engine:

* Always check the oil level before each use. The oil level should be between the "full" and "add" marks on the oil dipstick.

* Change the oil every 50 hours of operation or once a year, whichever comes first.

* Use only high-quality oil that meets the specifications recommended by Briggs & Stratton.

* Do not overfill the engine with oil, as this can cause damage to the engine.
