NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you're driving. How to Check and Add Oil Check oil only when the engine is cold. Allow the engine to cool two to three hours after running. CAUTION: If you remove the supercharger oil fill plug while the engine is hot, pressure may cause hot oil to blow out of the oil fill hole. You may be burned. Do not remove the plug until the engine cools. 1. Clean the area around the oil fill plug before removing it. 2. Remove the oil fill plug using a 3/16 inch Allen wrench. 3. The oil level is correct when it just reaches the bottom of the threads of the inspection hole. 4. Replace the oil plug with the O-ring in place. Torque to 88 lb-in (10 N·m). Supercharger Oil Unless you are technically qualified and have the proper tools, you should let your dealer or a qualified service center perform this maintenance. When to Check Check oil level every 30,000 miles (50 000 km) or every 36 months, whichever occurs first. What Kind of Oil to Use Use only the recommended supercharger oil. See "Recommended Fluids and Lubricants" in the Index. 6-21
