Step 1: Determine the required certifications. Engine oil is rated and certified by organizations such as API and SAE. Any brand of oil will be compatible as long as it meets the required certifications, listed in your operator's manual. John Deere Plus-50 is the recommended oil and meets all required certifications.

Step 2: Determine the required viscosity (or weight) based on the air temperature of the operating environment. Multi-viscosity oils are recommended and cover a broader temperature range.
Modern engine oils are a precise blend of highly refined oils and additives. This blend is designed and certified to give your engine the best performance and protection possible. Additional additives will upset this precise balance and may lead to engine damage. A thorough discussion on the history and use of additives can be found on page 10 of the John Deere Oil Guide. Using proper oils and following the recommended maintenance intervals is the best way to protect your engine. No engine oil additives of any kind are recommended or endorsed by John Deere. Any failure resulting from the use of additives or non-approved oils will not be covered by warranty.
Oil Change Intervals
All John Deere machines do not have the same recommended oil change intervals. For example, engines with larger quantities of oil may require less frequent oil changes. Be sure to read the operator's manual or maintenance guide for each John Deere product you own and follow the proper maintenance schedule.
The oil change intervals listed in your operator manual or maintenance guide are guidelines. Under some conditions, they may be extended if higher grade oils are used. In many cases, oil change intervals must also be reduced if lower grade oils or certain fuels are used. Consult your John Deere dealer before extending any maintenance interval, including oil changes.
Note:* Engine oil should be checked daily with biodiesel use. If biodiesel is found diluted into engine oil, reduce oil change interval by 50% and monitor oil quality closely.
A good quality oil filter is just as essential as good quality oil. Poor quality filters can reduce oil life and engine performance. However, selecting an oil filter is not as easy as choosing oil. There are a number of factors to consider, including:
All John Deere filters have been thoroughly tested in labs and fields across the globe to deliver unsurpassed performance. Before purchasing a competitive filter, use the links below to familiarize yourself with the characteristics that define a good quality oil filter.
Checking and changing oil on a regular basis is important. Equally important know what to watch for. Whenever oil is drained from the engine, it should be thoroughly inspected for the presence of water, engine coolant, or diesel fuel. Water and engine coolant will separate from the used oil and be especially easy to notice in the drain pan. These warning signs will often be accompanied by other problems such as a rough running engine, excessive or odd colored exhaust smoke, overheating, or poor performance in general. Contact your John Deere dealer immediately if you notice any of these signs.
OILSCAN fluid analysis kits are also available, which allow a sample of engine oil to be sent to a lab for analysis. Lab results can provide information about remaining oil life or contamination. See your John Deere dealer for more information about the costs and benefits of OILSCAN kits.
