* Check your owner's manual: The most important thing is to consult your owner's manual. It will explicitly state the recommended oil viscosity (like 5W-30, 5W-20, etc.) and specifications (like meeting certain API or ILSAC standards). The manual is the ultimate authority.
* 5W-30 is common: 5W-30 is a very common viscosity grade and is often a suitable choice for many vehicles, including some Dodge Calibers. However, your specific engine might prefer a different grade.
* Potential issues if incorrect: Using the wrong oil viscosity could lead to:
* Reduced fuel efficiency: Too thick an oil can increase engine friction.
* Increased wear: Too thin an oil might not provide sufficient protection against wear.
* Poor cold weather starting: A too-thick oil can make starting difficult in cold temperatures.
In short: It's unlikely to cause immediate catastrophic damage, but always check your owner's manual first. If you're unsure, consult a qualified mechanic or your Dodge dealer. Using the correct oil is crucial for engine longevity and performance.
