Browsing thru I found this old post and I wanted to add my comments. Although Red Line Oil is touted as a top-notch synthetic oil, oil analysis results show that, at least in passenger vehicle applications, it may not be formulated properly. Red Line oils are for TRUE racing applications. On passenger vehicles (cars and trucks)it has been determined thru testing that when using Red Line there is excessive wear metal content, low tbn value, excessive oxidation percentage and Molybdenum levels which are "over range". These results would seem to indicate that after a fairly short oil drain interval the Red Line Oil used was showing unacceptable levels of oil degradation, and the Polyolester base stock seems to be reacting negatively with the aluminum and lead materials in the engine. In addition, the "over range" Molybdenum levels indicated that Red Line may be using a solid extreme pressure additive in its oils. Although this may be useful (but is not necessary with top-quality basestocks) in RACING applications where metal components of an engine may be more likely to come in contact with each other, it is not necessary in a passenger vehicle engine and can actually be harmful to the engine. This would make sense, otherwise there would be no reason to indicate the levels of Molybdenum to be "over range".
