Purpose and Specifications

SWAG 99 90 6162 is premium green central hydraulic oil based on Pentosin CHF 7.1, perfect for BMW 5 Series (E34) power steering, hydraulic suspension, and central hydraulic systems from 1987-1996 models like 525i, 530i, and M5.

This 1-liter bottle (0.98 kg) delivers smooth steering and reliable hydraulic performance in everyday driving and harsh weather. It stays fluid from -40°C to over 130°C, preventing stiff steering in winter or pump failure in summer heat. Made in Germany for long-lasting protection against wear and leaks.

When to Use / Replace?

• Every 80,000-100,000 km or 4-5 years: Flush old fluid to avoid sludge buildup that causes noisy pumps or jerky steering.
• Use if your BMW service manual specifies CHF 7.1 or MB 343.0 – matches OE numbers like BMW 81 22 9 407 549.
• Ideal for cold climates: Flows easily at low temps for quick response; thickens properly at high temps to protect under load.
• Shelf life: 3-5 years unopened in cool, dry storage.
