![]() ![]() Of course, AMSOIL Dealers are much too educated on the technical aspect of lubrication and on the principles of ethical salesmanship to be swayed by unscientific and unprofessional marketing tactics. When all the appropriate, scientifically valid, repeatable tests are applied Series 2000 is clearly the better oil. Is AMSOIL 20W-50 Racing Oil better than Red Line? The fact is, lubricant performance should notÄepend on the uncontrollable reactions of blowby gases with the oil. Clearly, if blowby gases improved the anti-wear characteristics of lubricants, then lubricant manufacturers would expose their products to such gases during the manufacturing process. Red Line's claim that their oil is designed to become more effective as it reacts with blowby gases is absurd. This failure is the result of testing an oil along with its contaminants. The results were inconsistent with Red Line's and failed to meet the repeatability requirements of the ASTM D4172 test method. AMSOIL attempted to replicate Red Line's findings by testing samples of used oil. While Red Line states the service conditions under which the samples operated were the same, variables including fuel and glycol dilution, contaminant levels, filtration, driving conditions sampling techniques and many more are virtually impossible to control. First, the conditions of testing are uncontrollable. ASTM tests, as any informed entity in the lubricants industry knows, are designed for use with new (unused) lubricants, not used oil. The article, however, goes on to report results of used oil testing using the ASTM D4172 Test. That is, AMSOIL 20W-50 provided nearly three times better wear protection than Red Line 20W-50. Initial Red Line testing of an unused sample of AMSOIL 20W-50 Racing Oil in the ASTM D4172 Four Ball Wear Test yielded results consistent with those appearing on the product label. AMSOIL finds the article flawed in both its marketing approach and scientific methodology. Recently Red Line Synthetic Oil Corporation mailed an article to AMSOIL Dealers outlining results of testing done on AMSOIL 20W-50 Racing Oil and Red Line products.
