I cannot find any reference to 2 ethyl hexanoic acid (2-EHA) with regard to Peak Long Life Coolant or Peak Extended Long Life Coolant at the Peak web sites (www.peakauto.com and
http://www.peakantifreeze.com). But I did manage to find a technical discussion of the extended life antifreezes produced by Peak. See
http://www.peakauto.com/tech/tech_e.html which includes the following paragraph:
Quote:
Old World Industries manufactures two extended life antifreezes. PEAK Globalâ 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 Chargeâ 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.
To wit, in their technical discussion of extended life antifreeze products, Old World Industries only mentions Peak Global Lifetime and Peak Final Charge, their SCA pre-charged coolant for heavy duty diesel applications. What happened to Peak Long Life and Peak Extended Long Life? If you examine the filing dates on the MSDSs for these products, Peak Long Life was introduced a few months before Peak Global Lifetime (in 2004). Peak evidently decided that they needed a more aggressive marketing position for their extended life coolant and introduced the Peak Global Lifetime product name with a longer warranty. In the technical discussion, Old World Industries neglects to mention the marketing synonyms (Peak Long Life, Peak Extended Long Life) for Peak Global Lifetime because there are no technical differences among these products.
One more observation: on Peak's application chart, Peak Global Lifetime and Peak Long Life are recommended for EXACTLY the same set of applications, which includes essentially all recently manufactured light cars and trucks. (Many manufacturers forbid the use of 2-EHA in their vehicles so Peak Long Life cannot contain 2-EHA if Old World Industries is honestly representing their products.) In this chart, the only stated difference between Peak Global Lifetime and Peak Long Life (other than warranty) is color. Peak Global Lifetime is "amber" while Peak Long Life is "yellow". But the MSDS for Peak Long life states the the color is AMBER.
Has anyone bought bottles of the three Peak extended life antifreeze products for cars (Peak Global Lifetime, Peak Long Life and Peak Extended Long Life) and compared their appearance? I bet that they are indistinguishable.
