What kind of oil you can use for old dodge caravan 1992?

For a 1992 Dodge Caravan, you should use conventional 10W-30 motor oil. This is generally recommended for older vehicles unless the owner's manual specifies otherwise (always check your manual first!).

However, consider these factors:

* Owner's Manual: The owner's manual is the ultimate authority. Check it for the manufacturer's specific recommendation on oil type and viscosity. This will likely specify 10W-30, but there might be other acceptable options.

* Climate: If you live in an extremely cold climate, you might consider a 5W-30. For extremely hot climates, a 20W-50 might be suitable, but 10W-30 is a good all-around choice for most areas.

* Engine Condition: If your engine is worn, a slightly thicker oil like 15W-40 *might* be considered, but this should only be done after consulting a mechanic. Thicker oil provides better protection for worn engines but can hinder performance.

Important Note: Always use an oil that meets or exceeds the specifications listed in your owner's manual. Using the wrong oil can severely damage your engine. Don't just rely on general advice; consult your owner's manual first.
