Delo Introduces New Extended Life Coolant

February 13, 2008

SAN RAMON, CA – Chevron’s Delo brand of technologically advanced engine oils, lubricants, and coolants, has introduced the latest member of its product line, Delo Extended Life Coolant/Antifreeze — Nitrite Free (DELO ELC-NF). The new Extended Life Coolant (ELC) is recommended for use in on- and off-road heavy-duty equipment, as well as stationary applications, requiring a nitrite-free OAT formulation, as mandated by engine manufactures like Detroit Diesel.

In 2006, Detroit Diesel published DDC 93K217, which only allows the use of nitrite-free extended life coolants (OAT) in its engines. Delo Extended Life Coolant/Antifreeze — Nitrite Free helps ensure operators meet OEM warranty requirements.

Delo Extended Life Coolant/Antifreeze — Nitrite Free offers a service life of 600,000 miles, 12,000 hours, or six years, with no chemical extender needed. Other benefits of the new Delo ELC-NF include: increased corrosion protection and lower electrical conductivity; added protection against pitting, corrosion, and erosion even on hard-to-protect metals like aluminum; better heat transfer compared to silicate containing coolants; and improved water pump life due to its silicate-free formula. DELO ELC-NF is 100 percent compatible with DELO ELC, which contains nitrite. Like other extended life coolants in the Delo line, the new nitrite free ELC product is dilution tolerant up to 25 percent.

Delo Extended Life Coolant/Antifreeze — Nitrite Free is currently available in North America in pails, drums, and bulk, and will soon be offered in gallon jugs. 

Delo Extended Life Coolant/Antifreeze — Nitrite Free meets or exceeds the requirements of the Detroit Diesel/MBE, Cummins, MTU, European OEM’s like Volvo, Japanese OEM’s, ASTM D 3306, Performance requirements of ASTM D6210 and TMC RP 329, and OEM’S requiring a nitrite free extended life coolant based on carboxylate technology.

A new Texaco Extended Life Coolant, known as Texaco Extended Life Coolant/Antifreeze - Nitrite Free, has also been made available by Chevron Products Company. Texaco Extended Life Coolant/Antifreeze — Nitrite Free also meets the Detroit Diesel coolant specification 93K217 and offers identical performance characteristics to the new Delo product.
