Most modern lubricants work for their intended application. Few engines, transmissions, and differentials fail in normal low-mileage automotive service due to lubricant related causes. But most automotive lubricants are made for normal automotive service, not 150+ MPH or endurance racing. Under high-performance conditions is where we can see dramatic differences and failings of many conventionally formulated lubricants.

Red Line lubricants also excel in wear protection. Red Line provides several different antiwear additives in each lubricant to provide wear protection over a very wide range of conditions. The data from two ASTM wear tests below indicate that Red Line has a distinct ability to carry a greater load (film-strength), and that less wear is produced per unit of load. Across the range of loads which your automotive equipment can encounter, Red Line can provide less wear and a much lower chance of catastrophic failure than other petroleums and synthetics. This can make the difference between an engine saved and one which is destroyed when a mechanical component such as a connecting rod bolt breaks.

Another significant difference between Red Line and other synthetics and petroleums is the ability to withstand high temperatures without decomposition. The polyol esters used by Red Line have a significantly greater degree of thermal stability compared to the synthetic hydrocarbons and petroleum lubricants. In fact, the polyol esters are the only lubricants capable of properly lubricating a modern jet turbine engine. This enhanced thermal stability can provide improved lubrication in the extreme temperature regions such as turbocharger bearings and upper ring area, provide improved cleanliness, and allow extended high-temperature operation. The chart above compares the ability of several synthetic and petroleum lubricants to withstand decomposition at a temperature of 500°F for three hours.
