OEM Approvals
ECOSYN GE 4004 and GE 4006 meet and exceed the quality and lubrication requirements for leading gas engine OEMs worldwide.
About Approvals
Engine builder approvals confirm that ECOSYN GE oils meet or exceed the OEM's own lubrication specifications, giving operators confidence that the oil is validated for their equipment.
Models listed without a formal approval badge reflect specific field experience with ECOSYN GE 4004 or GE 4006. Additional OEM qualification tests are ongoing.
Always refer to the equipment builder's operation manual for the final lubrication recommendation. Contact us if you need guidance for a specific engine model.
