Lucas Oil Lucas Oil 50W Synthetic Transmission Lubricant, 5 Gallons

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.
