75W140-S
100% Synthetic lubricant for gearboxes

Description

PROLAB's 75W140-S 100% synthetic oil for gearboxes offers exceptional properties and outclasses standard oils by its polyvalency, its performance and its durability. 

Characteristics and Benefits

PROLAB's 75W140-S 100% synthetic oil for gearboxes contains excellent antifriction properties which considerably reduce bearing and gear wear while at the same time lowering operating temperatures. PROLAB's 75W140-S allows for lower inventories: as it can be used in a wide range of temperatures, it can replace a number of oil grades, namely, SAE 75W, SAE 80W140, SAE 85W140 and SAE 140. It also decreases production loss due to work stoppage for seasonal oil changes.  PROLAB's 75W140-S increases durability and improves heavy equipment performance even under very demanding weather conditions, from very hot to very cold.

Types of Application

Use PROLAB's 75W140-S in industrial gearboxes working in extreme conditions as well as in high-performance vehicles transmissions and differentials.

Directions for Use

Follow the manufacturer's instructions for the lubrication of the specific piece of equipment.

Notes

For better results, it is highly recommended to use PROLAB's DE-25 Decontaminant prior to using a new lubricant.

Warning

The 75W140-S 100% synthetic oil for gearboxes can be incompatible with some yellow metals (copper-zinc alloy, copper, etc.) depending on operating temperatures.
Do not hesitate to consult your PROLAB representative.
