Using John Deere Turf-Gard™ Oil ensures you are using the exact oil specified by John Deere engineers. The System uses John Deere Turf-Gard™ Oil. Remember, the System replaces a portion of your engine oil. John Deere's recommended oil service for 100 Series Riding Lawn Tractors 1, is to change the System every 50 hours or once a season, whichever comes first. And a cooler running engine and better filtering helps increase engine oil life. Which means you’ll get a cooler running engine. What’s more, the filter media is designed to resist breaking down in oil over time. This fully synthetic filter media has greater surface area which increases its capacity to hold harmful contaminants. We have developed a better filtration system and filter design for our 100 Series Riding Lawn Tractors 1. What do you mean, I will never have to drain oil from my engine again? How is that possible? The answer is simple. In fact, this System increases the amount of oil in the engine by nearly 40%. Here’s why: The new System captures contaminants and recharges your engine with nearly a quart (0.8qt) (0.76 l) of new oil.
