Consumer Benefits
  • Beneficial Formulation — The concentrated corrosion inhibitors are diluted in a 50/50 mix of water and ethylene glycol. Use of Delo FleetFix CME will not affect the freeze point of a cooling system for either conversion/maintenance/ extender as long as the cooling system is currently at a 50/50 dilution.
  • Easy to Use — Delo Fleetfix CME is easy to use - simply add to the cooling system at the appropriate level, whether it is being used as an extender, maintenance fluid or converting a system to Delo ELC. The Chevron Kool Tools Kit contains easy to use recommendation charts to assist with conversion/ maintenance/extending Delo ELC and protecting your cooling system.
  • Convenient Packaging — Delo FleetFix CME is available in 12/1 quart cases and can be used straight out of the box at the recommended level based on the cooling system requirements.

Long Service Life — When using Delo FleetFix CME properly, the Delo ELC coolant will have a service life of 600,000 miles/1,000,000 km/12,000 hours/6 years if correct top-up and maintenance practices are followed.


Wide Service Application — The Delo FleetFix CME product can be used by customers with on-road, off-road or industrial cooling systems.


Cooling systems converted using Delo® FleetFix® CME will meet the performance requirements of most major U.S. OEMs. This process has been used successfully in major engine types including Detroit Diesel, Caterpillar, Cummins, International, Mack and Volvo.
