SN/SM Engine Oil Additives Package T3260

SN/SM Engine Oil Additives Package T3260

Advanced Protection for Mid-Tier Gasoline Engines

T3260 has been developed to formulate high quality automotive engine oils and multigrade oils . The following performance levels can be achieved with oils formulated with T3260.

Product Introduction

T3260 is a precision-formulated additive package engineered for API SN/SM-grade engine oils, delivering enhanced anti-wear, deposit control, and oxidation stability. Balancing performance with cost-effectiveness, it extends oil life while maintaining compatibility with emission systems lacking GPF/DPF. Ideal for vehicles manufactured between 2004–2018 requiring robust protection without SP/GF-6 compliance.

Key Features

Controlled ZDDP : Reduces friction by 40% in ASTM D4172 tests while protecting catalytic converters from phosphorus poisoning.

Synergistic detergent/dispersant system minimizes piston carbon deposits by 60% vs. baseline oils (Sequence IIIG validated).

Inhibits viscosity increase (ΔKV100 ≤10% @ 1,000h ASTM D2272), extending drain intervals to 15,000 km in moderate conditions.

Sulfur content ≤0.4% (wt.) ensures compatibility with conventional three-way catalysts (OBD-II compliant).

30% lower treat cost vs. SP-grade packages, ideal for emerging markets and value-oriented lubricants.

Application

Passenger Car Engine Oils: API SN/SM formulations for non-turbo engines (e.g., Toyota ZZ, Honda D-series).

Hybrid Vehicle Ancillary Systems: Idle-stop motor protectors (JASO M364:2023 compliant).

Commercial Fleets: Taxis/delivery vehicles with 100,000–200,000 km mileage.

Emerging Market Lubricants: Cost-sensitive regions with limited SP-grade adoption.

Remanufactured Engines: Post-overhaul break-in protection (≤5,000 km usage).
