I thought I'd share my first oil analysis from
Blackstone Labs in case anyone was interested.
I am running the Amsoil dual remote bypass oil filter system. I did my first oil change at 5,700 miles back in February 2008. This was a complete oil and filter change. I used the Amsoil synthetic 15W/40. In the middle of October at 13,900 miles, I changed out both oil filters and replaced the lost oil (3 qts) with the same Amsoil synthetic. I collected the oil from the filter, which may have messed up the results a bit. Of course I realized this in hindsight.
Based on the results, I will probably do another full oil and filter change around 20k miles.
Here are the comments from Blackstone on the test results:
Quote:
Thanks for the note, that you've partially changed this oil. The fresh oil you’ve added should help dilute the wear concentrations that have built up in this oil. Copper and lead are from the bearings. We
are not sure why they're reading high, but silicon might have something to do with it, if the silicon is dirt. Suggest checking the entire air filtration system for leaks. Or, if this engine is still pretty new, the metals and
silicon could be leftover wear-in materials, in which case they'll drop next time. The TBN read 6.0, still plenty high. Check back in 8000-9000 miles.

The following were above the universal averages: Iron, Copper, Silicon, and Calcium. The rest of the results were average or below. The viscosity readings were also a little low. I will definitely continue to do these tests.
