Chevron’s Delo brand of technologically advanced engine oils, lubricants and coolants, has introduced the latest member of its product family, Delo 400 LE SAE 10W-30. The new Delo 400 LE multi-grade diesel oil is specifically formulated for new low emission engines running on ultra low sulfur diesel (ULSD) fuel.

Delo introduces new nitrite-free extended life coolant
Chevron’s Delo brand of technologically advanced engine oils, lubricants and coolants, has introduced the latest member of its product family, Delo Extended Life Coolant/Antifreeze – Nitrite Free (DELO ELC-NF). Its maker says 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, 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.

Cooling Systems: Problems & Solutions
Some while back, Bob Deierlein, our long-time research editor, wrote an article on cooling systems. In that article, he referenced some maintenance records of a large over-the-road fleet, which indicated that a substantial percentage of the fleet’s engine problems could be traced back to the condition of the truck’s cooling system. We published that article more than 20 years ago.
