It sounds too good to be true — a coolant that lasts at least 600,000 miles in your dump truck or 6,000 hours or six years in your excavator, tractor-loader-backhoe or other earthmoving equipment. That’s up to three times the life of a conventional coolant. Yet, that’s exactly the kind of performance you can expect from extended life coolants. So, what’s the catch? You’ll probably pay about 50 percent more for an ELC and you’ll have to add an extender at 300,000 miles, 3,000 hours, or three years. But look at what you get:• No need to add supplemental coolant
