Oil Companies Are in the aftermarket Additive Business, Proving they Work!
Thursday, April 16th, 2009
So many articles are written regarding how aftermarket additives do not work; buyer beware, fine chemical balance, waste of money and they just do not work. Most of the time these comments come from marketers of motor oils. Their customers ask them if an aftermarket additive will benefit their vehicle. The marketer, who sells motor oil, doesn’t want the customer to think his oil is inferior so tells the customer do not use. It becomes such a hassle explaining many have invested a great deal of time on blogs and other web activities telling the public to beware of additives.

Oxidation and Bearing Corrision Inhibitors
Tuesday, June 26th, 2007
Excessive engine heat causes oil oxidation, which in turn results in permanent thickening of the oil. Oxidation products can attack some bearing metals. This was a common problem in engines until research produced a chemical compound capable of interrupting or slowing down the rate of oil oxidation. It was discovered that several different oil-soluble chemicals would accomplish this. (more…)
