Medium Speed Sinopec Great Wall Marine Engine Oil 3012 4012 Anti Wear Dual Fuel

Sinopec Great Wall Marine Medium-Speed Engine Oil 3012 4012 Anti-Wear Dual-Fuel

Sinopec Great Wall Marine Medium-Speed Engine Oil 3012 4012

Great Wall marine medium-speed engine oil 3012/4012 is developed for the lubrication characteristics of four-stroke medium-speed diesel engines. It meets their cylinder and crankcase lubrication requirements and is especially suited to new four-stroke medium-speed diesel engines that run at higher operating temperatures and pressures.

Product Overview

This marine medium-speed engine oil is designed for four-stroke medium-speed diesel engines used at sea and on land. It delivers outstanding anti-wear performance that helps reduce wear on metal parts, and its excellent detergency and dispersancy reduce deposits to keep engine parts clean. Excellent thermal stability and oxidation stability help inhibit varnish formation, while good anti-rust and anti-corrosion performance protects engine parts. The oil meets the API CF specification and suits both single-fuel and dual-fuel operation.

• Outstanding anti-wear performance that helps reduce wear on metal parts.
• Excellent detergency and dispersancy that reduce deposits and keep engine parts clean.
• Excellent thermal stability and oxidation stability that help inhibit varnish formation.
• Good anti-rust and anti-corrosion performance that protects engine parts.
• Meets the API CF specification.
• Suitable for diesel, distillate and dual-fuel (LNG/diesel, LNG/distillate) operation.

Technical Specifications

Typical Data

Applications

• Four-stroke marine medium-speed diesel engines and four-stroke land medium-speed diesel engines running on diesel or distillate fuel.
• Dual-fuel four-stroke marine and land medium-speed diesel engines running on LNG/diesel or LNG/distillate.
• Stern shaft and other auxiliary equipment lubrication.

Why a Marine Medium-Speed Engine Oil Matters

Four-stroke medium-speed diesel engines work continuously under load, and newer designs run at higher temperatures and pressures than before. A marine medium-speed engine oil must control wear at the cylinder and crankcase while keeping the engine clean. This engine oil combines anti-wear additives with strong detergency and dispersancy, so it reduces wear and deposits at the same time. Its thermal and oxidation stability help prevent varnish, and its anti-rust and anti-corrosion protection guards engine parts during long service. For dual-fuel engines, its formulation also suits LNG/diesel and LNG/distillate operation.
