* Engine Type: There were multiple engine options for the 2001 Rodeo. The V6 3.2L engine is common, but there could be slight variations depending on the exact model.
* Climate and Driving Conditions: The recommended viscosity can vary depending on your location's climate and how you typically drive (city vs. highway, frequent towing, etc.).
* Oil Change Interval: The oil's viscosity will influence how often you need to change it.
* Owner's Manual: The most reliable information is always in your vehicle's owner's manual. It will detail the correct viscosity for your specific engine and year.
How to Find the Right Oil:
1. Consult Your Owner's Manual: This is the most important step. Look for a section on fluids and lubricants.
2. Check the Oil Dipstick: If your owner's manual doesn't have the information, check your dipstick. It might have a recommended viscosity printed on it.
3. Consult an Isuzu Dealer or Mechanic: If you can't find the information, contact a local Isuzu dealer or a qualified mechanic. They can help you determine the correct viscosity.
Remember: Using the incorrect oil viscosity can damage your engine. Always use the recommended viscosity specified by the manufacturer.
