409 MINERAL GEAR LUBRICANT
Non-EP Gear Lube For Manual Transmissions
PRODUCT DESCRIPTION
PENNZOILŪ 409 MINERAL GEAR LUBRICANT is a non-EP, straight mineral oil
manufactured from high quality,
high viscosity index paraffinic base stocks. These base oils offer inherent
oxidation stability for long service life, and
their high viscosity indices aid in maintaining optimum thickness and fluid
film strength as temperature increases.
PENNZOILŪ 409 MINERAL GEAR LUBRICANT contains no active extreme pressure
additives, and therefore will not
contribute to corrosion, etching, or wear of yellow metals, such as brass or
bronze. It is inhibited against foaming and
prevents rust from forming on metal parts. This lubricant meets API
designation GL-1.
Even though it is classified as an SAE grade 80W-90 multi-viscosity gear
oil, PENNZOILŪ 409 MINERAL GEAR
LUBRICANT contains no unstable polymers to artificially boost its viscosity.
This means that the lubricant will retain its
"body" and will not shear down during use, maintaining a strong, stable,
protective film, even under heavy loads and
high speeds. The low temperature flowability of an SAE 80W fluid provides
for smoother shifting in cooler weather and
better protection during lower temperature start-ups.
