Quote:
The major performance difference between extended life and conventional antifreeze is the life-span of the product. Conventional antifreeze lasts only two or three years due to depletion of the antifreeze corrosion inhibitors. Because the corrosion inhibitors are different, automobile extended life antifreezes last five years or 150,000 miles. Heavy-duty extended life antifreezes last between 400,000 and 600,000 miles with the use of a one time extender.
...
Old World Industries manufactures two extended life antifreezes. PEAK Global® LifeTime™ features a patented, advanced organic acid technoloy [sic] for automobiles and light-duty trucks that, with a complete flush and fill, provides a LifeTime protection guarantee - for as long as you own the vehicle. Final Charge® antifreeze is a red colored heavy-duty antifreeze. Because it is organic acid based, Final Charge antifreeze does not require SCAs when used in heavy-duty applications. Elimination of SCAs greatly reduces the cost and variability associated with heavy-duty cooling system maintenance.

* Provides 150,000 miles or 5 years of maximum protection when a complete cooling system flush and fill is performed
If Peak LongLife is a DexCool clone distinct from Peak Global Lifetime, then Peak manufactures three different extended life antifreezes: Peak Global Lifetime, Peak LongLife and Peak Final Charge. So who is right, Peak's Technical web pages or the Peak Tech Dept?
