The recommended oil viscosity for a Chevy 454 engine typically depends on the specific model year and operating conditions. Generally, a 10W-30 or 10W-40 oil is suitable for most climates, while a 20W-50 may be recommended for warmer temperatures or high-performance applications. Always consult the owner's manual for the specific vehicle to ensure the correct viscosity is used.
