Best Gear Oil for Differential


In small reservoir high-speed differential applications, conventional commercial gear oils offer little in the way of proper protective lubrication. When these differential units are exposed to too much foaming, this ultimately raises temperatures which lead to other problems that ultimately ruins both the differential unit and the lubricant. This gear oil was designed especially for these smaller reservoir high-speed differential units. It is the premier oil for differentials that will vastly reduce foam, heat, wear, and extend the equipment life of both the differential and the lubricant.

Best Gear Oil for Differential utilizes the finest 100% paraffin base stock oils with a viscosity index minimum of 95. These heavy-duty paraffinic base oils are extremely resistant to broad temperature changes. What this means is that Best Gear Oil for Noisy Differential will maintain its correct viscosity when temperatures are high or when temperatures drop. These base oils go through a 3 step refining process to reduce any undesirable impurities that could contribute to the formation of unwanted contaminants such as varnish and sludge. Most conventional oils do not formulate their products using base oils that have gone through this rigorous 3 step refining process. To these super-refined impurity-free base oils is added a robust and abundant quantity of additives, making Best Gear Oil for Differential the finest lubricant on the market for your hardworking differential.

With the advent of specialized aerodynamic bodies for over-the-road trucks and vehicles, which are designed to reduce air resistance, a byproduct of these aerodynamics is that they reduce the amount of cooling air flowing to the transmission area. Less cooling air results in higher operating temperatures. Add to that heavy loads and traveling at slower speeds creates an extreme operating environment for transmissions and differentials. Best Gear Oil for Noisy Differential was formulated to lubricate at much higher temperatures than conventional commercial gear oils. It is rated to perform at up to 100 degrees Fahrenheit higher. Overall, between the base oils and chemistry, this oil provides superior thermal stability, reduced parts wear, and the ability to extend oil drain intervals. This means less downtime and a savings and maintenance cost.

Many final drives and transmissions are forced to operate at much higher temperature ranges from 280 degrees Fahrenheit all the way to 320 degrees Fahrenheit. Operating at these extreme temperatures can cause an issue called synchronizer coking. Synchronizer coking causes difficulties in changing gears. If these deposits can be removed, then, of course, these shifting issues will disappear. Best Gear Oil for Differential utilizes its own proprietary additive chemistry engineered to perform at extremely high temperatures and offer the ability to prevent the formation of detrimental deposits such as gum and sludge. Consider the fact that this gear oil also offers superior thermal oxidation stability. Its resistance to oxidation helps to extend oil drain intervals and reduce unnecessary parts wear. Of course, with this heavy-duty additive package, synchronizer coking is non-existent due to its ability to withstand high temperatures. By keeping transmissions and final drives clean from sludge, gum, and unwanted deposits, the gear oil has a clear path to lubricate all bearings and gears when oil passageways and filters are not clogged with dangerous deposits.

Broad-based industry testing of transmissions and final drives has shown that temperatures around the seal area are exposed to high amounts of heat 30 degrees Fahrenheit to 50 degrees Fahrenheit range, which is beyond what is seen in the sump areas. These higher temperatures often lead to deposits forming around the seal area. These detrimental deposits can lead to elastomer losses, which can cause premature leakage. There seems to be evidence of a relationship between how severe the number of deposits found around seals and premature leakage. Best Gear Oil for Differential was engineered as a high-temperature gear oil that utilizes base oils and specialized chemistry that is fully compatible with seal material. It is proven to prevent unwanted deposits on and around seals. Also, our chemistry is fully compatible with seal materials. This gear oil will offer long life to seals when operating at extremely high-temperature situations and will eliminate and reduce the potential for premature leakage around seal areas.

Transmissions and final drives are subjected to extreme pressure loads and it is critical that the choice of gear oil offers protection against such shock loads. Best Gear Oil for Differential is formulated with the finest heavy-duty EP additive chemistry available on the market. Our oil was put through the industry-standard Timken OK Load test. Our SAE 90 Gear Lube scored a 70 pound Timken OK Load rating and our Best Gear Oil for Differential SAE 140 rated a full 75 pound Timken OK Load. These are superior results compared to conventional gear oils. By utilizing Best Gear Oil for Differential in extreme shock load operating conditions, gears will get the finest protection against wear. When gears are protected against unnecessary wear, temperatures drop, parts last longer, and maintenance costs are dramatically reduced. When comparing conventional GL-5 gear oils, Best Gear Oil for Differential has always outperformed the competition. Oil analysis has proven its superiority because it provides better gear surface spalling/fatigue resistance. These oil analysis shows must lower amounts of iron metal wear than conventional gear oil products.
