If you don't have the owner's manual, you can try these steps:
1. Locate the engine: Pop the hood and look for a sticker on the engine or in the engine bay. This sticker might specify the recommended oil type and viscosity.
2. Check the oil fill cap: Sometimes, the recommended oil type is printed on the oil fill cap.
3. Look up your vehicle's information online: Websites like the Dodge website (if they have historical information available), or a parts website using your VIN number (Vehicle Identification Number) may provide the information. Be very careful to use the correct VIN to avoid ordering the wrong parts.
4. Consult a mechanic or auto parts store: Provide them with the year, make, model, and engine size of your Shadow, and they can look up the correct oil for your specific car. This is the safest method if you are unsure.
Without knowing the engine size, it's impossible to give a definitive answer. Using the wrong oil can severely damage your engine. Always prioritize finding the information from your owner's manual or a reliable source before changing your oil.
