Go to their site and order a few free sample kits and the next time you change your oil, fill the small container mid-stream and send it off.
I would recommend that you pay the extra $10 for the TAN (Total Acid Number) test. This indicates how much of the additive package is still in the oil.
This short video from Motorvate's DIY Garage explains the three things to look for:

This is a good video, but wouldn't an oil analysis only tell me if the engine was wearing a lot during the time that oil was in engine? In other words, I could have worn a lot off of the engine during a track day a year ago. However, the oil change I do today would not show that because that oil already came out of the car.
We had perfect weather and the car ran really well chasing down lots of cars that were faster in a straight line, but not in the braking zones and corners. I also ran some of my fastest laps and significantly faster than before. The last time I was there I did everything possible to try to break 2:50, but it just wasn't happening. This time in the first session with TCS on I was running consistently in the 2:52 range and felt like TCS was interfering. The 2nd session I turned off the TCS and was determined to break 2:50. I ran one 2:48 lap and was thrilled. There was a guy next to me in my group with a 3,100lb supercharged mustang with 500+ hp who was running 2:46's so I felt pretty good. The next session I cracked a 2:46!?! The 4th and final session I got a number of 2:46 laps, but that is probably about as fast as this car will go without doing something too stupid.
The last time I was there I met a guy with a heavily modified current gen M3 who was running 2:43 laps and trying to carry 100 mph in the kink. This time I was pulling out of the kink at about 100 mph and running laps times within just a few seconds of him. I consider that a big win for this car.
On the last lap of my last session I was trying to chase down a ZL1 Camaro and was catching him in the corners, but he was pulling away from me in the straights. Coming into turn 5 at about 140+ I braked a touch later to make up some ground, but the brake pedal got soft and I had to pull off. 1st time I have ever cooked Motul RBF600 fluid. The front calipers are also a nice shade of bronze now. Guess I won't have to worry about painting them anymore.
Yes, no deer strikes. You do see them at the track once in a blue moon. Pretty rare, but a CART driver got injured from hitting a deer there about 10-15 years ago.

Heat did that? What color were they before? I don't remember.
And your front rotors... didn't you just get those last year? The discoloration on the rotor is disturbing. Track days sure do a number on your brakes.
The front brakes are about the same color as GT-R brakes now. They were more of a champagne gold color, which is what the rear brakes look like now. The rotors are fine. You are just seeing a bit of surface rust because it rained that day.

Oh jeez, you really cooked those things. I've never seen them that shade of bronze before. Mine were discolored from heat too (multiple 120 >50mph braking zones at Autoclub) and mine don't even look like that.

The used oil analysis will show the recent past of what was wearing in the engine due to the .8 litres that is still in the engine when we change the oil.
For example in the video below, the lead (crank bearings) spiked after a track day and has slowly come down, but still isn't at the pre-trackday level:
My G has been retired from track duty. Got my 2007 Miata rehab'ed and it ran well today. Gutted, race seats and harnesses, SCCA-legal roll bar, hard top, A/C delete including the compressor, CAI and a tune. Not as fast as my G but comparable lap times.
