After finding fine metal shavings on my oil drain plug, I got a Blackstone testing kit and had my next oil change checked. They results say everything is good, I was wondering though anyone else who has had Blackstone test oil could give me some comparasions for what numbers you got.

Aluminum:3
Chromium:2
Iron:12
Copper:18
Lead:1
Tin:0
Molybdenium:4
Nickel:0
Managanese:8
Silver:0
Titanium:0
Vandium:0
Boron:80
Silicon:5
Sodium:4
Calcium:875
Magnesium:1405
Phosphorus:669
Zinc:806
Barium:0

SUS Viscosity @210F: 55.4
Flashpoint in F:420
Fuel %: <.05
Antifreeze:0
Water:0
Insolubles:.1%

 

I'm due for another analysis soon, but here is the information I got from Blackstone for my first test. This one was done with only 7600 miles on the car, 4700 miles on Redline 10W/30, and all of the stock internals. As you can see, I'm also keeping my eye on a high Cu count.

Aluminum:10ppm
Chromium:1
Iron:17
Copper:196 <img src="gr_eek2.gif" border="0">
Lead:9
Tin:6
Molybdenum:464
Nickel:1
Manganese:2
Silver:0
Titanium:0
Vanadium:0
Boron:13
Silicon:25
Sodium:13
Calcium:2569
Magnesium:43
Phosphorus:1103
Zinc:1306
Barium:0

SUS Viscosity: 65.8
Flashpoint: 360F
Fuel %: <0.5
Antifreeze: 0
Water: 0
Insolubles:0.5

 

What do you think your high Cu is from?
