Description

Lucas Synthetic 50 WT Transmission Oil is designed especially for heavy duty truck transmissions but can be used in many other applications. Common gear oils are mostly base stocks with little more than an addition of sulfur and phosphorus as a total anti-wear package. We at Lucas Oil Products consider this inadequate. Most heavy duty truck transmission manufacturers now consider sulfur and phosphorus to be potentially corrosive to copper and brass and consequently recommend against common gear oils for this reason. The other 50 WT we have tested, synthetic or otherwise, are pure base stock, we consider this also inadequate. Lucas Synthetic 50 WT contains an exclusive additive concentrate derived from synthetic oil that ensures lower operating temperatures and better lubrication, especially to upper bearings and gears. This is a long lasting fluid that is far superior to conventional synthetic fluids and contains nothing that could be harmful.
