Every month or so, we’ve tried to provide you with lists of key terms to know for discussing Interim Tier 4 engines. Engine oils are an important component in maintaining your IT4 engine and ensuring the highest level of performance. Keep these terms in your back pocket when looking for engine oils for your new John Deere IT4 machines:

  • API – The American Petroleum Institute. This organization is responsible for classifying all engine oil types in the United States to make it easy for operators to find the right oil for their equipment.
  • ACEA – The European Automobile Manufacturers’ Association.  Similar to the API, this organization is responsible for classifying all engine oil types in Europe.

  • SAPS – Acronym for “sulfated ash, phosphorus and sulfur”, this term refers to the concentration of SAPS in different blends of engine oils. Interim Tier 4 engines require lower levels of SAPS to ensure maximum efficiency of the diesel particulate filters and diesel oxidation catalysts.
  • CJ-4 – The API oil classification type required for Interim Tier 4 engines. CJ-4 oil is backward compatible for use in Tier 3 and older generation engines. You can find a complete list of API licensed CJ-4 oil grades here. CJ-4 oils use certain new additives with rebalanced chemistry to reduce SAPS, and thus extend the service life of the diesel particulate filters and diesel oxidation catalysts.
  • E9 – The ACEA oil classification type required for Interim Tier 4 engines.
  • CI-4 – The API oil classification type used for Tier 3 and older generation engines. Interim Tier 4 engines should not use CI-4 or previous oil grades, only CJ-4 oils.
