Go Longer – A Lot Longer – Between Oil Changes with Oil Guard. Only on Vanguard.

While others are in a seemingly endless cycle of oil changes, Oil Guard lets you run 5X longer than typical engines between oil changes. The innovative 6-quart total oil capacity system extends the life of the oil and better protects the engine: extending your oil maintenance intervals to an industry-leading 500 hours. It’s like skipping four oil changes for every one you do. So, your teams can be more productive, and you can save more money.

  • Cost Savings - up to a 60% savings on oil maintenance costs, on every unit, every season*

  • Extends Engine Life - system minimizes thermal breakdown and keeps cooler, cleaner oil moving through the engine

  • Maintenance Simplified - fewer, faster, and easier oil changes

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