yes, simply put.
oil analysis will test the fluid and report back with what's in it. there's always some expected levels of each type of metal, specific to different parts of the engine.
here's a sample of a report. i've always liked blackstone labs
pay attention to the 'universal averages' and what they're pointing out in that report. excess wear indicates that something isn't right, or that would require different maintenance.
