The One-Arm Bandit has been used to show the extreme pressure benefits of some aftermarket oil additives by highlighting increased lubricant film strength and less scoring on the bearing. Additives demonstrated in the One-Arm Bandit can give the illusion that extreme pressure properties are desirable in motor oil. The concern with this attempt to link extreme pressure performance with long-term engine wear is that engines typically do not experience exceedingly high levels of pressure.

Although this demonstration tool may be used at trade shows to showcase the performance of lubricants and aftremarket additives, it is not an accepted test by the American Society for Testing and Materials (ASTM) and can be manipulated with different operating parameters to significantly change the out-put, making one believe an engine oil or oil additive is required for maximum engine protection. AMSOIL doesn’t require any aftermarket oil additives in any of there synthetic motor oils.
