recommended for use in truck, motor home / RV, and automotive front
or rear differentials, manual transmissions and lower gear units
of marine engines that specify use of an API GL-5 or GL-4 fluid.
an ultra-tough, high performance, GL-5 automotive gear oil designed
to provide maximum protection to heavily loaded gears while maximizing
power output throughout the drive train. It outperforms other GL-5
gear oils because it combines the highest quality synthetic oils
with Royal Purple's proprietary Synslide additive technology.
additive technology, Royal Purple's tough, EP lubricating film,
provides maximum protection under boundary lubrication conditions
typically caused by heavily loaded, slow speed and / or shock load
conditions. This tenacious, slippery film significantly improves
lubrication and reduces wear by increasing the oil film thickness
and toughness, which helps to prevent metal-to-metal contact in
gears and bearings.
additive technology is noncorrosive to gears and bearings, including
case-hardened gears that are easily pitted by conventional sulfur-phosphorus
EP oils. Synslide® additive technology displaces water from
metal surfaces and excels in protecting equipment in wet environments.
It also fortifies the oil against the detrimental effects of heat,
which causes oil to oxidize.
