Mobil Delvac™ Extended Life 50/50 Prediluted Coolant/Antifreeze
Ready-to-use, ethylene glycol-based coolant providing exceptional corrosion protection
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is a ready-to-use, phosphate-free, silicate-free, nitrite-free and borate-free, ethylene glycol-based coolant that is designed to provide exceptional wet sleeve liner cavitation and corrosion protection of all cooling system metals.
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is formulated with organic corrosion inhibitors to provide total cooling system protection for 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use). Since the organic corrosion inhibitors do not readily deplete, Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze eliminates the need for Supplemental Coolant Additives (SCAs) as required when using conventional coolants.
- Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is recommended by ExxonMobil for use in:
- All types of heavy-duty diesel, gasoline and natural gas engines
- Stationary engine applications regardless of fuel type being used
- Marine cooling systems where freeze protection is needed
- Mixed fleets where both light-duty and heavy-duty trucks are present
Features and Benefits
- Long Service Life: 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use)
- Designed for use in engines running EGR and SCR technologies that can increase cooling system temperatures
- Eliminates the cost of SCAs, test strips and manpower required to test the coolant and add SCAs
- Can accept up to 25% mixing with conventional coolant technologies, with no detrimental effect to corrosion protection or reducing the extended life properties
- Fully compatible with other quality Organic Acid (OAT) and Nitrited Organic Acid (NOAT) heavy-duty extended life coolants
- Nonabrasive formula can improve water pump seal life
- Optimal hard water compatibility and reduced hard water scale
- Provides outstanding long-term elastomer compatibility

To assure success using Mobil Delvac Extended Life 50/50, the system should be drained and flushed. Mobil Delvac Extended Life 50/50 is a ready to use product. To insure the proper concentration level of the inhibitors and boil-over/freeze protection, do not add water or mix with other unknown coolants.
With Mobil Delvac Extended Life 50/50 there is no need to use an initial charge of supplemental coolant additive or pre-charge spin on water filter.
Mobil Delvac Extended Life 50/50 is compatible with other ELC and conventional heavy duty coolants. Dilution with conventional coolants will reduce extended life benefits.
Mobil Delvac Extended Life 50/50 a new patented technology OAT – ELC + Nitrites – Molybdates, provides extended life protection that ensures performance to 1.000.000 km (600.000 miles) or 12.000 hours when refill is done with the same Mobil Delvac Extended Life 50/50.
