L1605 Antiwear (lubricate) Additive for Diesel

Introduction

L1605 is oil soluble liquid and compatible with all grades of low sulfur diesel. It can enhance the lubricating performance, to protect the diesel engine and improve operation.

Application

Recommended treatment level is 150~300 mg/kg.
Treatment level should be determined by lubricity test of base diesel.
