The John Deere D110 is a popular choice for homeowners who want a reliable and easy-to-use lawn tractor. For many, it offers the right balance of power, size, and comfort. But one key detail that often confuses owners is the oil capacity of the D110. Knowing the correct oil amount—and understanding how each part of your tractor’s oil system works—can make a big difference in performance and longevity. This article explains the John Deere D110 oil capacity in detail, with special attention to every aspect you need to know, including 110 specific components, steps, and tips. Whether you are a new owner or have years of experience, you’ll find practical, clear answers here.
John Deere D110 Oil Capacity Overview
The standard oil capacity for the John Deere D110 is 1.5 quarts (1.42 liters) with an oil filter change. This means that every time you change both the oil and the filter, you should add 1.5 quarts of oil for the engine to run smoothly. But there’s more to oil capacity than just a number. Let’s break down what this means for your tractor, why it matters, and how to ensure your D110 stays in peak condition.
Why Oil Capacity Matters
Using the right amount of engine oil isn’t just about following the manual. If you add too little, the moving parts in your engine won’t be protected. If you add too much, pressure can build up, causing leaks or even engine damage. For the John Deere D110, keeping the oil at the correct level helps ensure smooth starts, consistent power, and a longer life for your mower.

1. Engine Model
The D110 uses a Briggs & Stratton 31R907 single-cylinder engine, which determines oil specifications.
2. Standard Oil Capacity
The oil capacity is 1.5 quarts (1.42 liters) when changing both oil and filter.
3. Oil Type
Use SAE 10W-30 for most temperatures. This oil works best for the D110.
4. Oil Filter Type
The D110 uses an AM125424 oil filter, which must be changed with the oil.
5. Oil Drain Plug Location
The oil drain plug is on the side of the engine, easily accessible for draining.
6. Oil Fill Tube
The fill tube is usually yellow and located on top of the engine.
7. Oil Dipstick
The dipstick measures oil level—always check before starting the engine.

Practical Insights Most Owners Miss
Many new owners forget the first oil change is crucial—waiting too long after break-in can cause early wear. Also, when operating on hills or uneven ground, oil may shift away from the pickup tube. Always check the oil level if you mow on slopes.
Another non-obvious tip: If your tractor sits unused for months, old oil can corrode engine parts. Change oil before storage, not just after.
Troubleshooting: If Oil Level Seems Wrong
Sometimes, the dipstick reading is off due to air bubbles or a tilted engine. Re-seat the dipstick fully and check twice. If oil looks milky, water may be present—change oil immediately and check for leaks.
