You MUST check your owner's manual. It will specify the correct oil type (conventional, synthetic blend, or full synthetic) and viscosity (e.g., 5W-30, 10W-40). The viscosity is particularly important and using the wrong one can damage your engine.
If you don't have the owner's manual, you can:
* Check the oil fill cap: Sometimes the recommended oil type is printed on the cap.
* Look for a sticker under the hood: Many vehicles have a sticker detailing maintenance recommendations, including oil type.
* Use a vehicle identification number (VIN) lookup: Several online services allow you to input your VIN to get information about your vehicle's specifications, including recommended oil.
Do not guess. Using the wrong oil can severely damage your engine. Always refer to your owner's manual or a reliable source to determine the correct oil type and viscosity for your specific 1995 Chevy Silverado.
