For the 2016 Chevrolet Silverado 2500 HD with the 6.6L 8-cylinder LML diesel engine, the oil capacity is 10 quarts (including filter replacement). The preferred viscosity for temperatures above -18°C is SAE 15W-40, though 5W-40 is recommended for all temperatures when ambient conditions are below 0°F (-18°C) to improve cold starting. AMSOIL recommends using Signature Series 15W-40 Max-Duty Diesel Oil or Heavy-Duty 15W-40 Synthetic Diesel Oil paired with a high-efficiency oil filter.
What oil does a 2016 Chevrolet Silverado 2500 HD 6.6L LML take?
This vehicle requires an engine oil with a CJ-4 specification. For most operating conditions above -18°C (0°F), SAE 15W-40 is the preferred viscosity. However, if you operate in environments where ambient temperatures frequently drop below 0°F (-18°C), using a 5W-40 viscosity is recommended to improve cold starting performance.

About this vehicle
The 2016 Chevrolet Silverado 2500 HD is a heavy-duty pickup truck designed for high-capacity utility, specifically engineered for demanding tasks like towing and hauling. It is part of the Silverado range manufactured by General Motors and shares mechanical commonality with its GMC Sierra counterpart.
At the core of this vehicle is the 6.6L Duramax V8 diesel engine, a powerplant produced by DMAX, a subsidiary of General Motors. The Duramax engine family has been a staple in GM trucks since 2001 and is recognized for its heavy-duty reliability and long-term durability. Because these engines are specialized diesel powerplants, they require specific maintenance focuses, including turbocharger health, diesel injection component care, and strict adherence to fluid service intervals.
Owners of this platform often research towing capacities, Diesel Exhaust Fluid (DEF) management, and methods to improve engine longevity under heavy loads. Given the high-performance nature of the Duramax, proper lubrication and filtration are central to maintaining the vehicle’s performance profile.
Common questions about this vehicle’s diesel oil and maintenance
What is the oil capacity for my 6.6L Duramax?
