Chevron Marine Lubricants has introduced a new range of premium high-performance gear oils designed for use in industrial and marine clutched gear systems, where extreme load and shock load protection is required.

In developing Meropa MG gear oils, Chevron Marine Lubricants has responded to customer and original equipment manufacturer (OEM) demand for gear box oils designed to ensure optimal performance in Renk and Flender/Siemens, Reintjes and Brunvoll clutched gear boxes, extensively used in marine vessels. Meropa MG gear oils carry approvals from those gear box manufacturers, and also meet or exceed various industrial standards.

Chevron says the advanced formulation of Meropa MG gear oils is balanced to help provide both extreme pressure protection, while providing defence against yellow metal corrosion. Oils in the range are designed to offer long lubricant life, corrosion protection, good wear protection with high load carrying capacity and robust micro-pitting wear protection. Additionally, the thermal and oxidative stability of Meropa MG gear oils helps to minimise deposit formation, prevents varnish and sludge and keeps the components clean which can extend bearing and gear life.

Uniquely, says Chevron, the new gear oils are suitable for use in clutched gearboxes required to pass the Ortlinghaus clutch test, a seal of approval not granted to regular oils that usually do not meet its requirements.

Meropa MG gear oils are also formulated to alleviate a common issue encountered with the use of gear oils. Over-aggressive chemistries in some other oils frequently attack gear box paint coatings and can cause filter plugging. However, the chemistry of Chevron Marine Lubricants’ new gear oils is designed to be compatible with multiple types of sealant and paint coatings and helps to prevent this issue, minimizing the possibility of leaking seals and paint blistering on the inside of the gearbox.

Meropa MG gear oils are available in the ISO VG 100/150/220 viscosity range and will be supplied in all Scandinavian ports. Depending on demand, supply areas could be expanded in the near future.
