Chevrolet Silverado: Fuel / Recommended Fuel (6.2L V8 Engine)

Chevrolet Silverado 2019-2025 Owners Manual / Driving and Operating / Fuel / Recommended Fuel (6.2L V8 Engine)

Premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 93 — (R+M)/2 — is highly recommended for best performance and fuel economy. Unleaded gasoline with an octane rated as low as 87 can be used. Using unleaded gasoline rated below 93 octane, however, will lead to reduced acceleration and fuel economy. If knocking occurs, use a gasoline rated at 93 octane as soon as possible, otherwise, the engine could be damaged. If heavy knocking is heard when using gasoline with a 93 octane rating, the engine needs service.

Do not use any fuel labeled E85 or FlexFuel. Do not use gasoline with ethanol levels greater than 15% by volume.
