SWEPCO 202 SAE 75W90 Gear Oil
Background:
The SWEPCO family of high performance gear oils has a new member: SWEPCO 202 SAE 75W90 Gear Oil. This long awaited version is ready to meet or exceed your needs. For many years the usual automotive gear oil viscosity was among others: 80W90, 90, or 80W140. These oils performed well and will continue to do so for years to come.
Enter the Clean Air Act requiring the reduction of emissions from all sources. One way to reduce emissions is to improve fuel economy by reducing friction. This led to changes in fuels, fuel systems, engine oils, and now transmissions / differentials. To reduce friction in gear oils required a change in base fluids, additives, and improving low temperature properties. This new oil has low temperature properties and requirements below previous specifications.
The Product:
SWEPCO 202 SAE 75W90 is a fully synthetic gear oil with a high performance automotive additive package. It has been proven that synthetic oils have lower internal friction and lower resistance to flow, making them ideal for reducing overall friction. They also provide better low temperature properties for ease of shifting at start up and on cold days. Synthetic fluids also have long drain intervals (using oil analysis!) and when properly formulated, good seal compatibility.
SWEPCO 202 SAE 75W90 Gear Oil contains Lubium® II for extended oxidative life and better yellow metal protection for critical parts. This will protect the fluid and components from high temperature operations, inhibit sludge formation, and long hauls for longer fluid life. A premium performance package is utilized for maximum gear protection, wear reduction, and superior performance. MolyXP is included in this high performance package to further reduce friction and provide a layer of Molybdenum Disulfide on the gear surface.
The name 202 was chosen to separate these unique properties from the other gear oil lines. As an added bonus, SWEPCO 202 SAE 75W90 Gear Oil also contains Limited Slip Additive for use in differentials equipped with that option.
Applications:
Use SWEPCO 202 SAE 75W90 Gear Oil where this unique viscosity is called for. Most new trucks with manual transmissions require this grade both in the transmission and the differential. Many late model cars with manual transmissions also require 75W90 synthetic oils.
