Purpose and Specifications

Castrol 15D675 is a premium semi-synthetic hydraulic oil designed for heavy-duty automatic transmissions and hydraulic systems in trucks, buses, and industrial equipment. This 1-liter bottle delivers exceptional wear protection, smooth shifting, and long-lasting performance in demanding conditions.

It meets strict approvals like Allison TES 389, MB 236.9, MAN 339 Typ V1, Volvo 97341, ZF TE-ML 04D, and Ford MERCON, ensuring compatibility with top manufacturers. The advanced formula resists oxidation up to 18,000+ hours in lab tests—far longer than standard oils' 2,000 hours—meaning fewer changes and less downtime. It handles normal operations up to 99°C while staying fluid in cold starts, preventing pump damage and leaks.

• Practical benefits: Cuts varnish and sludge buildup for reliable power transfer.
• Superior foam control and filterability keep systems clean and efficient.
• Protects against rust and water contamination for equipment life extended by thousands of kilometers.

When to Use / Replace?

Use Castrol 15D675 in high-pressure hydraulic systems, automatic transmissions, and power shifts where OEM specs match. Ideal for construction, mining, and fleet vehicles operating in varied temps from -25°C to 99°C.

Replace every 50,000-100,000 km or 24 months under severe duty (dust, heat, heavy loads); double intervals versus conventional oils thanks to premium stability. Shelf life is 5 years unopened in cool, dry storage.
