## Overview

Castrol 157EF3 Optigear Synthetic 800/220 is a high-performance synthetic gear oil designed for heavily loaded gears operating across a wide temperature range. Featuring polyalkyleneglycol-based fluids, it offers exceptional thermal and chemical stability, superior anti-wear and extreme pressure protection, and excellent corrosion resistance—even in wet conditions. Compatible with most mineral, ester, and synthetic oils, it extends lubricant and machine life with longer drain intervals, making it the go-to choice for professionals demanding reliability and efficiency.

## Description

Castrol optigear synthetic 800 range (previously called tribol 800) Synthetic gear oils have been developed for the lubrication of heavily loaded gears, bushings and bearings which may operate over a broad range of temperatures from ambient to elevated temperatures (> 80°C/176°f). they are particularly intended to extend the service life of both lubricant and machine parts where unusually high operating and oil reservoir temperatures are encountered. The high performance characteristics of optional synthetic 800 are achieved with select polyalkyleneglycol (PAG) based synthetic fluids. They feature chemical and thermal stability, high viscosity index, water solubility, and compatibility with metals and elastomers most commonly used in machine construction. The naturally high resistance to oxidation of the synthetic based fluid is further enhanced by inhibitors. Corrosion protection Is very effective even in the presence of water. Also, a package of high performance additives acts in combination for superior anti-wear and extreme pressure (EP).
