Vanguard Expands Oil Change Intervals

By Briggs & Stratton   


April 27, 2017 - Briggs & Stratton Commercial Power introduces the Vanguard™ Oil Guard System for its 810cc EFI V-Twin and BIG BLOCK™ commercial engines.

Oil Guard is a first-of-its-kind solution for the commercial engine market, offering major productivity gains and allowing for 500-hour oil change intervals.

Vanguard engineers developed the system in conjunction with Ferris®, a Briggs & Stratton brand. The technology first launched on 2017 Ferris mowers, and Vanguard is actively exploring additional commercial applications for the innovative system.

“Oil Guard completely alters the way our customers look at oil changes. But, at its core, this new system is about increasing productivity — the same driving force behind all Vanguard innovations,” said Rick Zeckmeister, vice president of marketing and planning at Briggs & Stratton. “Vanguard’s ability to work with its sister company, Ferris, provided unique development insights from the perspective of an equipment manufacturer and helped us engineer a better overall solution. This oil management system shows strong potential for commercial applications outside of turf.”

The Vanguard Oil Guard System works by continuously exchanging oil between the engine and a 5-quart external oil reservoir. Its design protects oil from thermal breakdown, which extends oil maintenance intervals and produces a cooler-running engine. Direct access to the oil filter and drain tube results in quicker, easier and mess-free oil changes.


Contractors operating commercial equipment with a Vanguard engine featuring the Oil Guard System will extend their recommended oil change intervals from 100 to 500 hours. This decreases the time and costs associated with conducting oil changes.

The Vanguard Oil Guard System is a factory-integrated technology, not an aftermarket add-on, so Vanguard’s 3-year commercial engine limited warranty applies.
