However, generally speaking, older Jeep Wranglers often used:
* SAE 10W-30: This was a common viscosity for many engines of that era. Again, check your owner's manual.
* Type of Oil: The type of oil (conventional, synthetic blend, or full synthetic) is less critical in a 1993 vehicle than the viscosity. Conventional oil is fine for most older vehicles unless you're experiencing specific problems. If you want better performance and protection, a synthetic blend or full synthetic is an upgrade.
Before you buy any oil, find your owner's manual. It will specify the correct oil type and viscosity for your engine. Using the wrong oil can seriously damage your engine. The oil type and viscosity will be listed either under "Maintenance" or a section specifically dedicated to engine oil.
If you don't have the owner's manual, you can try finding a digital copy online by searching for "[your engine type] 1993 Jeep Wrangler owner's manual" . The engine type is usually printed on a sticker in the engine bay.
