For four-cycle motorcycles, we recommend Mobil 1 Racing 4T 10W-40 and Mobil 1 V-Twin 20W-50. These products are designed specifically for four-cycle motorcycles, including wet clutch applications. If your boat engine calls for an API SM, SL, SJ, SH or SG rated oil, you can use Mobil Clean 5000. However, we recommend that you follow the recommended oil change interval in your owner's manual.
Obviously, if you have a two-cycle motorcycle or outboard engine, you must use a two-cycle oil. (Updated June 2006)

| If I go longer between oil change intervals, do I need to change my oil filter more frequently? Or do I need a special filter? |
