Lawn Mower Oil & Engine Lubrication Guide

A key part of being an owner of outdoor power equipment, such as a lawn mower or snow blower, is knowing how to maintain your machine’s small engine. And a key part of small engine maintenance is keeping it well-lubricated.

In this guide, learn more about how lawn mower oil and engine lubricant keep your engine running right for years of productive use.

The Importance of Engine Lubrication

How important is engine lubrication, and how does it work? The lubrication system plays an integral role in maintaining engine performance. Briggs & Stratton® engines are designed to provide proper engine lubrication under a wide variety of operating conditions.

Proper engine lubrication ensures engine reliability and longevity. Oil reduces engine temperature and friction between components, for better performance and longer engine life.

Briggs & Stratton sets the industry standard for small engines with a lower oil “pick-up point,” which protects engines against wear when operating at angles or running low on oil. This is great news for owners of outdoor power equipment featuring Briggs & Stratton engines.
