15W40 Super D Gallon

Description

Overview

Shell Rotella T4 Triple Protection 15W-40 Conventional Heavy Duty Diesel Engine Oil (550045126) is designed for heavy-duty diesel engine lubrication across a wide range of on-highway and off-highway applications, including both pre-2007 engines and modern emissions-equipped platforms.

Technical Features

• API CJ-4 Certified Formulation: Meets the API CJ-4 service category standard, ensuring compatibility with the latest heavy-duty diesel engine requirements and emissions hardware.
• Improved High-Temperature Oxidation Resistance: Resists oxidation up to 50% longer than the previous generation of Shell Rotella T, reducing oil degradation under sustained high-temperature operating conditions.
• Enhanced Wear Protection: Delivers significantly lower wear compared to previous formulations, extending engine component life across high-load duty cycles.
• Exceptional Deposit Control and Engine Cleanliness: Improved formulation actively controls deposits, maintaining internal engine cleanliness and supporting consistent performance over service intervals.
• Shear-Stable Viscosity: Offers enhanced protection against viscosity loss due to shear, helping maintain proper oil film thickness throughout the drain interval.
• Low-Ash Formulation: Reduced ash content helps protect exhaust catalysts and diesel particulate filters (DPF) from fouling and premature degradation.
• Emissions System Compatibility: Formulated to sustain the durability of diesel particulate filters and after-treatment systems, supporting compliance with modern emissions standards.

Applications

• Pre-2007 heavy-duty diesel engines requiring conventional 15W-40 engine oil
• Modern heavy-duty diesel engines equipped with diesel particulate filters (DPF) and after-treatment systems
• On-highway and off-highway diesel-powered commercial equipment
• Applications requiring API CJ-4 specification engine oil
