2019 Chevrolet Silverado 3500HD Oil Capacity & Filter Guide

The 2019 Chevrolet Silverado 3500HD takes either 6.0 quarts of 5W-30 oil for the 6.0L V8 gas engine, or 10.0 quarts of 15W-40 or 5W-40 oil for the 6.6L Duramax V8 turbo-diesel engine, including the filter replacement. Getting the correct fluid capacity and spec is critical to keeping this heavy-duty workhorse running smoothly whether you are towing, hauling, or daily driving.

Quick answer

Here are the essential oil change specifications for the 2019 Chevrolet Silverado 3500HD.

For the 6.0L V8 Gas Engine:

• Capacity: 6.0 quarts (5.7 liters) with filter
• Recommended Weight: 5W-30
• Oil Spec: GM dexos1 Gen 2 / Gen 3 (API SP)
• OEM Oil Filter: ACDelco PF48E
• Aftermarket Filters: Fram PH10060 (or XG10060), Wix 57060, Mobil 1 M1-113A

For the 6.6L V8 Duramax Diesel (L5P):

• Capacity: 10.0 quarts (9.5 liters) with filter
• Recommended Weight: 15W-40 (for temperatures above 0°F) or 5W-40 (for all temperatures/severe cold)
• Oil Spec: API CJ-4 or CK-4
• OEM Oil Filter: ACDelco PF26
• Aftermarket Filters: Fram PH9100, Mobil 1 M1-303

Capacity by engine option

Because the heavy-duty Silverado was offered with two vastly different powertrains in 2019, you must verify which engine is under the hood before buying your oil.

Oil change interval

Your 2019 Silverado 3500HD is equipped with GM's Oil Life System (OLS), which calculates oil deterioration based on engine RPM, temperature, and miles driven. However, general guidelines apply:

• Normal Duty: For standard highway driving and light loads, you can typically go 7,500 miles (gas) or up to 10,000 miles (diesel) between changes, or when the OLS dictates.
• Severe Duty: If you frequently tow heavy trailers, carry maximum payloads, idle extensively, or drive in dusty environments, reduce your interval to 5,000 miles. Diesel owners doing heavy towing should monitor the OLS closely, as it will drop rapidly under extreme loads.

Drain plug torque

• Drain Plug Torque: 18 lb-ft (25 Nm) for both the 6.0L gas and 6.6L diesel engines.
• Crush Washer: The factory drain plug uses an integrated rubber seal or a separate crush washer. Always inspect the gasket on the plug; if it is flattened, torn, or weeping, replace the plug or the seal before refilling.

How to change the oil

1. Warm up the engine: Run the truck for a few minutes to warm the oil, allowing it to drain faster and suspend any contaminants.
2. Locate and remove the drain plug: Position a large drain pan (minimum 12-quart capacity for the diesel) under the oil pan. Remove the 15mm drain plug and allow the oil to drain completely.
3. Replace the oil filter: Move the pan under the oil filter. Use a filter wrench to loosen and remove the old filter.
4. Install the new filter: Lubricate the rubber O-ring on the new filter with a dab of fresh oil. Thread it on by hand until the gasket makes contact, then tighten it another 3/4 to 1 full turn. Do not overtighten.
5. Reinstall the drain plug: Wipe the mating surface on the oil pan clean. Install the drain plug and torque it to 18 lb-ft.
6. Refill the engine: Pour in the required amount of fresh oil (6.0 qts for gas, 10.0 qts for diesel).
7. Check the level: Start the engine and let it run for a minute to build oil pressure and fill the filter. Shut it off, wait five minutes, and check the dipstick to ensure the level is correct.
8. Reset the Oil Life System: Navigate through your driver information center menus to the Oil Life screen, press and hold the checkmark (or trip reset button) to reset it to 100%.

Common issues / tips

• L5P Duramax Filter Location: The oil filter on the 6.6L L5P is easily accessible from the bottom, but it holds a significant amount of oil. Loosen it slowly and let it drain over the pan to avoid a massive mess.
• Diesel Exhaust Fluid (DEF) Contamination: Never mix oil and DEF. If you accidentally spill DEF into the engine oil fill, do not start the truck, as it will cause catastrophic engine failure.
• Check Your Dipstick: HD trucks consume a small amount of oil under heavy towing conditions. Make it a habit to check your oil level at every fuel fill-up, especially if you are towing across the country.
