HOW OIL GUARD GOES 500 HOURS
- High-capacity 5-quart external oil reservoir keeps oil and the engine running cooler and cleaner
- A unique dry sump system ensures off-angle lubrication and minimizes thermal breakdown of oil
- Easy-fill cap and integrated oil filter make oil changes easier, cleaner and faster
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.
