To find the correct oil, you should:
1. Consult your owner's manual: This is the most reliable source. It will specify the recommended oil viscosity (like 5W-20, 5W-30, 10W-30, etc.) and type (conventional, synthetic blend, or full synthetic). The manual may also specify API certifications (like SN, SM, etc.).
2. Check the oil fill cap: Sometimes, the recommended oil type is printed on the oil fill cap.
3. Look up your vehicle's specifications online: Websites like the Lincoln website (if it has historical data) or a reputable parts retailer's website (like AutoZone, Advance Auto Parts, or Napa Auto Parts) allow you to enter your vehicle's year, make, and model to find the recommended oil.
Without knowing the year and engine of your Lincoln Town Car, I cannot give you a specific oil recommendation. Using the wrong oil can damage your engine. Always consult your owner's manual first.
