Hi
Here is the results for a 5000 mile run with a filter change at 3000 miles and 1/2 qt of makeup oil at that time.
The first filter was a PF52 and last was a Baldwin equiv of the AC.
Engine had 78k mi on it at end of OCI.
Aluminum.......2
Chromium.......1
Iron..............6
Copper..........18
Lead..............5
Tin................1
Molybdenum....26
Nickel.............0
Manganese.......0
Silver.............0
Titanium.........0
Potassium........2
Boron.............11
Silicon............20
Sodium...........38
Calcium.........1633
Magnesium.......389
Phosphorous.....636
Zinc...............851
Barium..............0
Fuel Water 0.0
Anti Freeze ??
Insolubles 0.4
This is a replacement engine with about 70k mi when installed. It had the composite UIM which I ran for the first month. The engine was orig a Dexcool fill and some of it remaining within the block contaminated my G-05 fill in the bottle.
I decided to replace the composite Upper I.M. with a Alum L26 UIM and do the LIM at same time.
I used "the right stuff " gasket maker and red RTV sealer in the install process.
The engine, after install, was flushed with SuperTech 10w-30 and then the GC went in. This was in early June this year. The coolant was completely flushed with clear water then G-05 went back in.
It took about 2-3 weeks to get the G-05 mixture to desired freeze/boil strength. This is now mid July.
Since Mid July, no drop in coolant. Infact to this very day, no drop in coolant.
I noticed that the orig Delphi UIM, once cleaned up , had degraded in the EGR passageway. Cannot say if it was leaking coolant at the tiem of replacement, but it did look like failure was immenient.
