The science of triboligy is the quality and grading of lubricants.Of the 5 classes of motor oil or transmission fluid class 1,2,are crude oil products used in most autos engines and transmissions Class 3 are semi-synthetic
or fully synthetic oils i.e.:Castrol Syntec.Class 4 motor oil or trans. oil is
exclusive Mobil 1 Fully synthetic,Class 5 is a ester based oil. Ester base oils
are unique synthetic formula that is the same molecular structure as whale oil.The classification is what the base stock of a quart of oil is made from.
A fully synthetic oil made with a ester base stock has a much higher burning point.Test for yourself:Very hot day :engine oil is hot:open fill
cap watch as the oil inside your engine is smoking.Next oil change use Red Line and same test:no smoke.
30000 mile transmission oil changes are better with Red Line ATF-4 than with BMW oil.Red Line starts with Ester base oils the same oil that is used in every Jet aircraft engine turbine and hydraulic system.
