Oil capacity by engine

Engine	Oil Type (viscosity)	Capacity w/ Filter	Capacity w/o Filter	Notes
6.0L — High Country, 6.0L Eng VIN G, RWD, 6.0L Eng	API - SAE 5W-30	6.00 QTS.	5.50 QTS.	Use only engine oil licensed to the dexos1 specification, or equivalent. ACDelco dexos1 Synthetic Blend is recommended. Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Check to be sure the oil is approved to the dexos1 specification. For areas of extreme cold, where temperatures fall below -20Deg.F (-29Deg.C), it is recommended a SAE 5W-30 synthetic oil or a SAE 10W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. DO NOT use other viscosity grade oils such as SAE 10W-30, 10W-40, or 10W-50.

Frequently asked questions

What type of oil does a 2018 Chevrolet Silverado 3500 HD take?

It depends on the engine: 6.0L uses 5W-30; 6.6L uses 15W-40.

What is the oil capacity of a 2018 Chevrolet Silverado 3500 HD?

Oil capacity depends on the engine: 6.0L holds 6.0 quarts with filter; 6.6L holds 10.0 quarts with filter.

How often should I change the oil in my 2018 Chevrolet Silverado 3500 HD?

Most 2018 Chevrolet Silverado 3500 HD owners follow a 5,000–7,500 mile interval with conventional oil, or up to 10,000 miles with full synthetic. Always check the oil life monitor if equipped, and consult your owner's manual — Chevrolet recommends intervals based on driving conditions, not just mileage.

Can I use synthetic oil in my 2018 Chevrolet Silverado 3500 HD?

Yes. 5W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 2018 Chevrolet Silverado 3500 HD. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
