This is like car companies telling you that plugs will last 100,000 miles. The Car Dr. agrees they will, but try to get them out at that mileage and you will see that they have degraded to the point where easy removal is an impossibility. Dexcool was initially marketed as a long life universal automotive engine coolant that would last 5 years or 100,000 miles of service. It is now marketed to last to 150,000 miles of service. Manufacturers of traditional antifreeze/coolants generally market that their antifreeze/coolants will provide dependable thermal control and corrosion rust protection for 24 months or 30,000 miles. The major difference in Dexcool over traditional coolants is in the corrosion inhibitor protection. Traditional antifreeze/coolants contain inorganic salts of borate, phosphate, silicate and other chemicals to prevent rust and corrosion, whereas Dexcool's corrosion inhibitor components are based on organic acid technology. Since the suit covers cars going back to 1996, it is clear that the class action is charging that the cancerous-like conditons get worse and worse over time. The product going into our Elises is, as far as I can tell, identical to Dexcool. Note that Dexcool is manufactured, and marketed by Chevron/Texaco, and
Texaco is the offerer of Havoline brand
products, of which the coolant in the Elise is. P.S. - Being the supplier of your own coolant in all the cars produced by car companies means having access to large, continuous profits. Do you think they are going to scrap Dexcool unless they are forced to? I'm sure the 'powers that be' are fully aware of the short-comings in their product but would rather continue to tweak it over whatever time is necessary, hoping to eventually come up with a less volatile coolant. So what if internal parts wear out in half the time they would using traditional coolant. The bean counters would consider that a long-term good thing, since more parts would be sold more quickly. For them it's a win-win.
