Through a new formulation, Chevron Products Co. is boosting the lifespan of its Delo and Texaco Extended Life Coolants (ELC) to 8 yr./750,000 mi., and to 15,000 hr. for off-road use.
If an extender is added at 4 yr./500,000 mi./10,000 hr., the ELC should last for 8 yr./1,000,000 mi./20,000 hr., Says Chevron.
According to Carmen Ulabarro, coolant marketing specialist, “You just need to check the coolant's freeze point every two years to make sure it's protecting down to between -12 and -62°F., topping it off as needed with a 50/50 coolant-water mix, and making a visual check of coolant to see if it's still red and that there's no debris in it.”
Ulabarro also said that since the new ELC “has tested well in EGR engines, we think we're prepared well to handle 2007, though we won't know for sure until we get it in some of the '07 engines and see what happens.”
