Engine Lubrication: How Briggs & Stratton Engines Work
With this video, you’ll find out how lubrication systems ensure Briggs & Stratton engines perform at their peak and last longer via 3 oil distribution methods.

While the exhaust keeps small engines in your lawn mower or outdoor power equipment from overheating, the engine lubrication system reduces friction to keep it cooler and prevent damage to components.

The innovative Briggs & Stratton design has a lower “pick-up point” for the oil. This strategic design ensures proper lubrication even if the engine is at an angle or you’re running low on oil.

3 Types of Briggs & Stratton Engine Lubrication Systems

Splash System: Oil is distributed via a gear-driven dipper or slinger in the crankcase. Depending on the engine type, it uses a rod connected to the piston (horizontal shaft engines) or spinning gear with paddles (vertical shaft engines) to pick up oil from the reservoir and sling it to components. This prevents clogging in small passages.

Pressure System: Oil distribution occurs as a controlled flow of clean lubricant to prevent deterioration and extend the life of the engine. Pressure lubrication systems use a pump in the oil pan to dispense the oil. It also includes a spin-on oil filter.

Full Pressure System: These work like engines in cars to deliver a continuous flow of oil. Full pressure systems maximize lubrication and protection against engine damage. With high-efficiency pumps and a premium spin-on oil filter, these lubrication systems provide automotive-style oil distribution for unsurpassed durability that removes up to 95% of contaminants.
