To find the correct oil weight, you should:
1. Check your owner's manual: This is the most reliable source. The manual will specify the recommended viscosity (e.g., 5W-20, 5W-30, 10W-30) and the oil type (synthetic, conventional, etc.).
2. Look at the oil fill cap or sticker under the hood: Some vehicles have this information printed on a sticker located under the hood.
3. Consult a reliable online resource: Websites like the manufacturer's website (Dodge/Stellantis) or a trusted automotive parts retailer can provide recommendations based on your vehicle's year, make, and model. Be sure to enter the complete information accurately.
Using the incorrect oil weight can damage your engine. Always use the weight recommended by the manufacturer.
