AMSOIL Industrial BENZ UCF 1 CALIBRATING FLUID is precision engineered for the calibration of diesel pumps and injectors by manufacturers and professional repair shops. It mimics diesel fuel in viscosity and specific gravity, while delivering wear protection, deposit prevention and a high flash point, providing extended life and superior validation process reproducibility.

• Meets ISO 4113-CV-AW standard to ensure the highest diesel calibration performance.
• Tight manufacturing tolerances for precise and repeatable results.
• Inhibits oxidation to help prevent varnish, sludge and deposit formation in fuel systems.
• Low odor improves working environment.
