Oil guard means increased productivity. 

Extended Oil Maintenance Intervals

At the very heart of Vanguard is a passion for helping drive productivity. For a commercial cutter, the biggest productivity robber is downtime for scheduled maintenance. With that in mind, Vanguard looked for ways to reduce downtime associated with the most significant maintenance item – engine oil. The result is the groundbreaking Oil Guard System. Applying the same technology used in other high performance, highly demanding applications, we developed a dry sump system that can be integrated into our Big Block and 810 vertical shaft V-Twin engines.

Benefits of the Oil Guard system:

  • 500-hour recommended oil change intervals (as opposed to typical 100 hours)
  • Cleaner, easier, faster oil changes
  • Reduces downtime for oil maintenance
  • Saves money: up to 60% on oil maintenance costs*

Protects Your Engine. Saves You Money.

Reducing downtime is a key to maximizing productivity. That’s the idea behind the Oil Guard System by Vanguard. By extending oil change intervals from a typical 100 hours to a whopping 500 hours, the Oil Guard System keeps equipment in the field, working longer.

Adapting dry sump technology from other high performance conditions,Vanguard was able to protect the oil by storing it in an external reservoir, rather than the engine sump. The higher volume of oil along with Oil Guard’s aluminum reservoir protects and cools the engine’s oil. Oil Guard’s unique automotive-style cartridge filter is 82% larger and 80% more efficient than our standard oil filters; further protecting engine oil, and in turn the engine.

Time isn’t the only thing you save with the Oil Guard System. It also saves you money. Fewer oil changes means reduced oil maintenance costs as well, saving you up to 60% on oil maintenance costs*, per unit, per season. When added to the reduced downtime associated with scheduled oil maintenance, the savings really begin to pile up.

Extended recommended oil change intervals, cleaner, easier, faster oil changes, reduced downtime for oil maintenance, and up to 60% savings* on oil maintenance costs. Only from the Oil Guard System. Only from Vanguard.


*Cost savings based on standard oil maintenance with 100 hour interval versus Oil Guard System 500 hour service interval.
