Mobil Delvac Extended Life 50/50 Prediluted Coolant / Antifreeze (Case of 6 - 1 Gal. Containers)
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is ready to use right as soon as it arrives. It provides excellent protection of all cooling system metals using organic corrosion inhibitors that protect cooling systems for 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use). Since the organic corrosion inhibitors don't easily deplete, there is no need for Supplemental Coolant Additives that are required when using conventional coolants. Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antrifreeze is phosphate-free, silicate-free, nitrite-free, and borate-free, and has an ethylene glycol base.
