Here is what Blackstone had to say about my second fill analysis that had 5400 miles on it:


"The high metals marked in the spectral examination are from the lower end, so bearings were having some difficulties during this second oil use interval. It may have been a little early to push your oil use miles. Note silicon, which is mostly sealer materials used at the factory, but some of it is abrasive dirt. It should drop to half this level in the next sample. Go ahead and run 5,000 miles for the next sample. Hopefully, the bearing wear metals will drop to about average. Other than the silicon, we found no harmful contamination in this oil. Upper end wear was normal."


Copper= 54ppm (Universal average for this engine type= 9ppm)


Lead= 11ppm (Universal average for this engine type= 4ppm)


Tin= 6ppm (Universal average for this engine type= 1ppm)


Silicon =50ppm (Universal average for this engine type= 2ppm)





So, what do you gurus think? Am I headed for lower end problems? Could this silicon level have anything to do with being on the beach for a week?

How many miles on the Engine ,I see you have a 04 ???


High then normal readings are normal with break in ....


What brand and viscosity of Erl are you using ,all are a factor too ...





Mac

At the time, the truck had 7500 total miles on it. This oil sample was actually the third fill. (Factory oil, then one change at apx. 2100 miles and then this fill which had 5400 miles on it)


I use Delo 400 15w40.





Ya, Im hoping its just that the motor is still breaking in....

I would think it will improve over time. mine has. my last sample at 41k was:





Copper= 10ppm


Lead= 7ppm


Tin= 2ppm


Silicon =7ppm





That is 3500 mi and about 30 dyno pulls on the oil. Oil is delvac1, tested by www.avlube.com (http://www.avlube.com). its also possible you got bad sample..
