Key Facts
- John Deere recommends consulting the owner’s manual for the exact type of oil recommended for the LA145.
- For gasoline-powered engines, including those on riding mowers, John Deere prefers the use of 10W-30 oil.
- The “W” in 10W-30 indicates that the oil was tested at low air temperatures, making it viscous even at temperatures as low as negative 4 degrees Fahrenheit.
- In climates where temperatures do not go below zero, John Deere suggests using 15W-40 oil for temperatures that do not go below 5 degrees Fahrenheit.
- For colder climates, 5W-30 oil is recommended for temperatures between negative 22 degrees and 104 degrees Fahrenheit.
- John Deere recommends using their own brands of engine oil, as they have additives and performance enhancers that reduce corrosion and keep internal engine parts running cleaner.
- Other brands of engine oil can also be used as long as they prevent sludge, resist foaming, perform within the indicated temperature ranges, and reduce corrosion while cooling and lubricating internal engine parts.
Recommended Oil Types
John Deere strongly recommends consulting the owner’s manual for the exact type of oil specified for the LA145 model. The manual provides precise guidelines based on the specific engine and operating conditions. Generally, John Deere prefers the use of 10W-30 oil for gasoline-powered engines, including those found in riding mowers.
