What oil does a 2018 GMC 3500 Duramax take?
The recommended oil for a 2018 GMC 3500 Duramax diesel engine is 5W-40 synthetic oil. This engine oil specification ensures proper lubrication and performance for the Duramax V8 diesel powertrain in the 2018 GMC 3500 heavy-duty pickup truck.
Detailed Explanation
The 2018 GMC 3500 is a heavy-duty pickup truck powered by the Duramax 6.6-liter V8 diesel engine. This robust engine requires a specific type of engine oil to function optimally and maintain its long-term reliability.
According to the manufacturer's recommendations, the 2018 GMC 3500 Duramax should use a 5W-40 synthetic motor oil. This oil viscosity provides the necessary lubrication and protection for the engine's critical components, even under heavy-duty hauling and towing conditions.
Key Reasons for 5W-40 Synthetic Oil
- Viscosity: The 5W-40 rating ensures the oil flows easily at low temperatures during cold starts, while also maintaining sufficient thickness at high operating temperatures to prevent wear and tear.
- Synthetic Formulation: Synthetic oils are engineered to provide superior performance, better oxidation resistance, and enhanced protection compared to conventional mineral-based oils.
- Diesel Engine Requirements: Diesel engines like the Duramax V8 have unique lubrication needs due to the higher pressures and temperatures they operate under. 5W-40 synthetic oil is specifically formulated to meet these demands.li>
Using the recommended 5W-40 synthetic oil in your 2018 GMC 3500 Duramax will help ensure optimal engine performance, extended component life, and compliance with the manufacturer's warranty requirements.

What kind of oil does a 2024 Duramax take?
If your 2024 Chevrolet Silverado is outfitted with a 2.7-liter turbocharged engine, you will want to use SAE 5W-30 viscosity grade motor oil. If your Silverado comes equipped with a 3.0-liter Duramax turbo-diesel, it's important to use SAE 0W-20 DexosD diesel engine oil.
Which is better, 5W40 or 15w40?
Both will have a viscosity of a 40 grade. That cannot be said for both oils during the dead of winter. The 5w-40 will have a lower viscosity when the engine is started than the 15w-40; consequently the 5w-40 will start easier and lubricate quicker in the cold than the 15w-40.
