Always use PS4 5W-50 engine oil or another full synthetic 5W-50 high quality oil for the SLINGSHOT vehicle. See the Recommended Service Products section for the part numbers of recommended service products.

Engine Oil Level

The oil fill cap and dipstick are located under the hood, on the engine. Always use the recommended oil.

NOTICE
The engine must be at normal operating temperature when checking or changing the oil. Do not check or change the oil when the engine is cold.
  1. Position the vehicle on a level surface. Place the transmission in neutral. Engage the park brake.
  2. Start the engine and allow it to idle for 2-3 minutes. Stop the engine.
  3. Wait 3 minutes before checking the oil level. This allows the oil to settle to the bottom of the crankcase. Do not check the oil level immediately after stopping the engine.
  4. Open the hood. See the Hood section for details.
  5. Remove the dipstick. Wipe it dry with a clean cloth.
  6. Reinstall the dipstick. Make sure it’s fully seated.
  7. Remove the dipstick and view the oil level. Maintain the oil level between the ADD and FULL marks on the dipstick. Add oil if necessary. Do not overfill.
    NOTICE
    If oil level is at “ADD”, about 1 qt. (946 ml) is needed to reach the “FULL” mark.
NOTICE
A rising oil level between checks in cool weather driving can indicate contaminants such as fuel or moisture collecting in the crankcase. If the oil level is over the full mark, change the oil immediately.

Engine Oil / Filter Change

Always check and change the engine oil at the intervals outlined in the Periodic Maintenance Chart. Always change the oil filter whenever changing oil.
NOTICE
The engine must be at normal operating temperature when checking or changing the oil. Do not check or change the oil when the engine is cold.
