Mobil Commercial Vehicle Lube, United States

Product Description 

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 base 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 a 50/50 mix of Mobil Delvac Extended Life Coolant/Antifreeze and deionized water.

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

Application

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.
