Looking over that report, the iron levels are also a bit higher than they should be, however all the other wear metals look normal. So it's also possible that chromium was a false high reading and if you have another analysis done on your next oil change the number might be back down to normal (which would be around 1ppm)
As a comparison, here is my last oil analysis on my C6, which had just over 10,000km on the oil:
Iron 12
Lead 6.4
Aluminum 2.7
Copper 54
Chromium 0.7
Nickel 0
Titanium 0
Tin 0
Silver 0

Where do you get yours done Pat?

Jack, I get mine done at Wearcheck, which is located in Burlington near Appleby Line and the QEW.

When they test the oil they also test for it's viscosity, but it's the value at 100c that they test, so it will only determine the second of the two viscosities on the label, and it also tests what the viscosity is at that point, which can be thicker or thinner than the original viscosity. In this case the final viscosity was a 20 weight oil, even though it started out as 5w30.

When you fill out the form there is a spot where you put down the viscosity and brand of oil but I've often had them put down the wrong info in my reports as well, so it's simply human error on the lab tech's part.
