Infineum D3398

Infineum D3398 is a high-performance additive package developed by Infineum for the formulation of heavy-duty diesel engine oils. Designed to formulate lubricants meeting API CI-4 performance requirements, Infineum D3398 supports the production of SAE 10W-30, 15W-40, and 20W-50 engine oils when used with approved base oils and suitable viscosity modifiers. Its balanced additive technology provides reliable protection for modern diesel engines operating under severe service conditions.

Formulated for use with Group I and Group II base stocks, Infineum D3398 provides excellent wear protection, soot dispersancy, piston cleanliness, and oxidation control, making it well suited for both on-highway and off-highway diesel engines. Its proven performance profile also supports long engine life, reduced deposit formation, and dependable performance under high-load operating conditions.

Recommended Dosage

The typical treat rate is 12.0% by weight, depending on the approved base oil selection and target formulation. Additional viscosity modifier and pour point depressant additives may be required to achieve the desired SAE viscosity grade and finished lubricant performance.

Blending and Storage

• Blend under controlled manufacturing conditions with continuous agitation where possible.
• Avoid localized overheating during blending and storage.
• Use electrical, steam, or hot-oil heating systems with a self-limiting maximum temperature not exceeding 120 °C (250 °F).
• Store in clean, dry, well-ventilated conditions.
• Protect from moisture, contamination, and direct sunlight.
• Follow standard lubricant additive handling and storage practices.

Packaging

Infineum D3398 is available in standard industrial packaging and bulk quantities, depending on regional availability and customer requirements.
