To determine the correct oil, you should:
* Check your owner's manual: This is the most reliable source of information. It will specify the recommended oil viscosity (e.g., 5W-30, 10W-40) and type (conventional, synthetic blend, or full synthetic).
* Look for an oil fill cap sticker: Sometimes, the recommended oil type and viscosity are listed on a sticker under the hood, usually near the oil fill cap.
* Use a reliable online resource: Websites like the manufacturer's site (Chevrolet) or a reputable parts store (like AutoZone, Advance Auto Parts, etc.) can help you find the correct oil based on your El Camino's year, make, model, and engine. You'll typically need the Vehicle Identification Number (VIN) for the most accurate results.
Simply knowing it's a Chevy El Camino isn't enough to determine the correct oil. The engine size and year significantly impact the oil requirements.
