1025R Engine Oil Capacity(+ Best Recommended Oils)

One of the most important aspects of maintenance is monitoring and replacing engine oil. In this guide, we’ll cover everything you need to know about the 1025R engine oil capacity, recommended oil types, and maintenance tips.

1025R Engine Oil Capacity

The John Deere 1025R engine oil capacity is approximately 5.3 quarts (5 liters) with a filter change and about 4.8 quarts (4.5 liters) when topping off without changing the filter.

It is recommended to use diesel engine oil that meets CJ-4 or better specifications, with common grades including 10W-30 for moderate climates, 15W-40 for high-temperature or heavy-duty use, and 5W-40 for cold conditions.

Regular oil checks and changes every 100 hours of operation or annually help maintain engine performance and prevent wear, leaks, or overheating.

Always ensure the oil level is between the “full” and “add” marks on the dipstick, replace the oil filter with every oil change, and use high-quality oil to prolong engine life.

Recommended Engine Oil for John Deere 1025R

Choosing the right oil type is just as important as maintaining the correct oil level. John Deere recommends using diesel engine oil that meets the specifications for CJ-4 or better.

Synthetic or semi-synthetic oils are preferred for their superior performance and longer service life.

Here are the most commonly recommended oil grades for the 1025R, depending on the operating temperature:

  • 10W-30: Suitable for most conditions and commonly used in moderate climates.
  • 15W-40: Ideal for high-temperature environments or heavy-duty operations.
  • 5W-40: Best for cold climates, ensuring smooth starts and proper lubrication at low temperatures.

Using oils that meet John Deere’s specifications ensures that your engine maintains optimal performance while protecting against wear, deposits, and corrosion.

How to Check and Change Engine Oil

1. Park the Tractor on Level Ground: Ensure the tractor is on a flat surface and the engine is turned off. This allows for an accurate oil level reading.

2. Locate the Dipstick: The dipstick is usually located near the engine block. Pull it out, wipe it clean, and reinsert it fully. Then, remove it again to check the oil level.

3. Assess the Oil Level: The oil should be between the “full” and “add” marks. If it’s low, add the recommended oil gradually and recheck.

4. Drain the Old Oil: Place a suitable container under the drain plug, remove the plug, and allow the old oil to drain completely.

5. Replace the Oil Filter: Unscrew the old filter and replace it with a new one. Apply a thin layer of oil to the rubber gasket of the new filter to ensure a proper seal.

6. Add New Oil: Pour the correct amount of new engine oil based on the 1025R’s capacity. Start with slightly less than full capacity, then run the engine for a few minutes and recheck the level. Top up as needed.

7. Check for Leaks: After adding oil, inspect the engine for any leaks around the drain plug or oil filter.

Oil Change Interval

John Deere recommends changing the engine oil on the 1025R approximately every 100 hours of operation or at least once a year, whichever comes first. If you operate in harsh conditions such as dusty environments or extreme temperatures, it may be necessary to change the oil more frequently.

Regular oil changes remove contaminants and prevent the buildup of sludge, ensuring that the engine continues to operate efficiently and reliably.

Signs Your Engine Oil Needs Attention

Being proactive about oil maintenance can save you from expensive repairs. Watch for these signs that your engine oil may need attention:

  • Dark or Dirty Oil: Fresh oil is typically golden brown. Dark, dirty oil indicates it’s time for a change.
  • Unusual Engine Noises: Knocking or ticking sounds may signal inadequate lubrication.
  • Oil Leaks: Puddles under the tractor or oil stains indicate a leak.
  • Excessive Smoke: Blue or black smoke from the exhaust may indicate oil burning or contamination.

If any of these signs appear, check your oil level and condition immediately.

Tips for Maintaining Your 1025R Engine

  1. Use High-Quality Oil: Always use oils that meet or exceed John Deere specifications.
  2. Monitor Oil Levels Regularly: Check your oil at least weekly, especially during heavy use.
  3. Change Oil and Filter Together: Replacing both ensures contaminants are removed effectively.
  4. Keep the Engine Clean: Dirt and debris around the engine can affect oil performance and lead to overheating.
  5. Record Maintenance Dates: Keeping track of oil changes helps maintain a consistent schedule and prolongs engine life.
