What is Oil Guard?
The engine is one of the most important parts of a lawnmower, and Oil Guard can only be found on Commercial Vanguard Engines. The Vanguard Oil Guard System is a groundbreaking system that allows professional landscapers to reduce downtime by increasing oil life and mower efficiency. The system has three main components. One, an easy fill cap with an integrated oil filter, allowing for easier, cleaner and faster oil changes. Two, a dry sump system which ensures off-angle lubrication and minimizes the thermal breakdown of oil (read on to learn about dry sump systems). Three, a high capacity (6 qt.) external engine reservoir. These three components make up the most advanced oil system ever found on a small engine.
Benefits of the System
Now that you know what three components make up the Vanguard Oil Guard, let’s discuss the benefits the system brings. The system as a whole will allow for more time between oil changes and save you up to 60% per year on oil. The recommended oil change interval is 500 hours which is generally an entire mowing season. Also, your engine will remain fully lubricated even when mowing at an off-angle because of the location of the reservoir and the amount of oil it holds. Read on to learn more about each of the components and how they make the Vanguard Oil Guard a great choice for any commercial mower.
Easy Fill Cap w/ Integrated Oil Filter
The Easy Fill Cap and Oil Filter makes changing oil easier and faster than ever before. No more lifting the mower or fussing with a screw on oil filter. The integrated oil filter uses cyclonic filtering technology which is 80% more efficient than a standard screw on filter. Moreover, the cyclonic filter reduces oil aeration. Furthermore, you don’t need tools to do an oil change anymore. Simply unscrew the oil plug and remove the old filter. After a few minutes, replace the oil plug and insert a new oil filter. From there, all you do is ill the oil tank with 5 qts. of fresh oil and your mower is ready to go!
Dry Sump System
You may have heard of a dry sump system before, but probably not in the context of small engines. Dry sump systems are common in high-performance race cars and equipment of the sort! A dry sump system keeps the oil stored outside of the engine. A traditional small engine has a wet sump system in which the oil is stored in the crank case of the engine. This means the oil is being constantly heated and there is only space for about 2 qts of oil on average.
Introducing a dry sump system reduces thermal breakdown by storing the oil outside of the engine. In addition, the oil has time to cool down before cycling back through the engine because it is cooled on the way back to the reservoir. The reservoir itself is made of aluminum which further helps the cooling process. Beyond allowing the oil to cool, there is just more oil to begin with.
High Capacity Reservoir
The Vanguard Oil Guard System holds a total of 6 qts of oil. The reservoir holds 5 qts and there is about 1 qt held up within the engine. Having this massive amount of oil reduces the risk of engine failure and allows you to comfortably mow at off-angles. Additionally, the external reservoir allows the filter to function more efficiently. This means the oil stays cleaner longer.
