* If it has the 3.0L V6: This engine likely called for 10W-30 or 5W-30 oil meeting the API service classification of SG, SH, or SJ at the time. Modern equivalents would be 5W-30 or 10W-30 meeting SN or SN Plus.
* If it has the turbocharged 3.0L V6: This engine usually had more stringent requirements. Consult your owner's manual to be certain, but it likely recommended a higher-quality oil such as a synthetic blend or full synthetic, and potentially a higher viscosity, such as 10W-40 or even 20W-50 depending on climate and driving conditions. Again, check the manual for the specific API service classification.
Crucially: Always check your owner's manual. The manual will provide the most accurate and up-to-date information for your specific vehicle. Using the wrong oil can damage your engine.
