Had blackstone run an analysis. Oil was solaris LLX 507. 15k on sample, engine is 04 PD with about 132k. There are some things to worry about here... please comment. Air filter is stock. Car sees a lot of idling, LOTS of wide open throttle redline runs, the car is a messenger vehicle. 5spd. EGR is deleted.
ALUMINUM - 11 (they say its too high!)
IRON - 155 ????????
COPPER - 6
SILICON - 5
all other metals are under 5
Viscosity is 64.8 @ 210F
11.56 @ 100C
Flashpoint 420
Fuel less than .5
Insolubles .4
TBN is 2.0 (almost gone)
Also, about 1 quart of makeup oil used. This is my second run of ELF 507.
I will note that about half of that makeup quart was from dealer castrol 505.01.
"Adam: Aluminum and iron both read high in this sample, and show some piston scuffing and higher wear at steel parts like cylinders. Universal averages show normal wear levels from this type of engine after about 8,000 miles use on the oil. This oil was run a lot longer, so that accounts for some of the iron, though we cant blame all of it on that and a longer oil run should not have caused aluminum to read this high. Suggest dropping back to a 10,000 mile run and check back"
SO any clues to why iron and alum are so high? Is something self destructing?
