Product Range — Gear Oils

German-formulated gear oils built for heavy loads and constant shear.

Rovex Gear Oils protect manual transmissions, axles and differentials under extreme pressure and high temperatures — formulated in Germany, blended at our Saudi Arabia plant for Gulf and African fleet conditions.

Gear Oils
Why Rovex Gear Oils

Engineered for extreme pressure, not just lubrication.

Gear oil works under conditions engine oil never sees — metal-on-metal shear, shock loading, and sustained high temperatures inside sealed housings with no airflow. Rovex Gear Oils are formulated with extreme-pressure (EP) additive packages that hold up under that kind of stress, across manual transmissions, differentials, and final drive axles.

Our Gear Oils Range

Full gear oil range — GL-4 to GL-5, light to heavy duty.

From manual car transmissions to heavy-duty truck differentials, Rovex covers the full range of gear protection needs.

Common Questions

Gear Oils FAQs

What's the difference between GL-4 and GL-5 gear oil?

GL-5 contains a higher level of extreme-pressure additives, designed for hypoid differentials under heavy shock loads. GL-4 has a moderated additive level safe for manual transmission synchromesh systems, which GL-5 can damage in some applications.

Can Rovex Gear Oils be used in both axles and manual transmissions?

Yes — our GL-4 grades are formulated for manual transmissions, while GL-5 grades are built for hypoid differentials and axles. Check your equipment manufacturer's specification before selecting a grade.

Are synthetic gear oils worth the extra cost?

Synthetic gear oils offer better low-temperature flow, extended service intervals and improved fuel efficiency, making them worthwhile for fleets prioritizing reduced maintenance and operating costs.

Do you supply gear oil to distributors across Africa?

Yes. Rovex Gear Oils are available to distributors across African markets in addition to our core Gulf operations.
