Castrol Optigear Gear Oils: A Smart Choice for Industrial Reliability

When it comes to protecting gears and heavy-duty equipment, not all lubricants are created equal. Choosing the right gear oil is not just about cost per liter — it’s about ensuring long-term reliability, reducing downtime, and optimizing overall operating costs.

The Castrol Optigear range — including Optigear BM 100 and Optigear Synthetic PD ES — is engineered to deliver superior performance where conventional gear oils often fall short.

Why Optigear Stands Out

✔ Superior Wear Protection
Optigear gear oils utilize advanced Microflux Trans Plastic Deformation (MFT-PD) technology, which helps smooth gear surfaces under load and significantly reduces wear — even in extreme operating conditions.

✔ Lower Friction & Energy Loss
By reducing friction between moving parts, Optigear helps minimize energy loss, lower operating temperatures, and improve overall system efficiency.

✔️ Extended Oil & Equipment Life
Longer oil life means fewer oil changes, reduced maintenance frequency, and increased equipment uptime — all contributing to lower total cost of ownership.

✔️ Versatile for Industrial Applications
From spur and bevel gears to planetary gear systems and rolling bearings, Optigear Gear oils are designed to perform reliably across a wide range of demanding industrial environments.

Castrol Optigear BM 100 — **Optigear BM 100**

A high-performance extreme pressure gear oil designed for heavily loaded industrial gearboxes and bearings. It provides excellent protection against scuffing, shock loads, and micro-pitting while improving friction performance.

Castrol Optigear Synthetic PD ES — **Optigear Synthetic PD ES**

For more demanding applications, this synthetic gear oil offers even lower friction and enhanced protection across a wider temperature range — making it ideal for high-temperature and high-load environments.

What Makes Optigear Different?

Microflux Trans Plastic Deformation (MFT-PD) Technology

Both Optigear BM 100 and Optigear Synthetic PD ES are powered by Castrol’s proprietary MFT-PD technology.

Unlike conventional additives that wear off over time, this technology actively improves gear surface structure, leading to:

Reduced friction compared to conventional oils
Extended lubricant and component life
Lower wear and reduced micro-pitting
Improved energy efficiency and system reliability

This results in smoother operation, less heat generation, and longer-lasting equipment — especially in high-load or continuous operation scenarios.

A Smarter Approach to Gear Oil Selection

In today’s industrial environment, selecting the right lubricant is a strategic decision. With Optigear, the focus shifts from upfront cost to long-term value — delivering improved reliability, reduced maintenance, and lower total operating costs.
