Here are the results of my first UOA on my 2007 HHR with a Ecotec 2.2 powerplant (automatic)
Ran Factory Fill in it to about 1100 miles and then changed out to the Valvoline 5W30 All Climate and ran that to just under 3K miles. Filter used was a Supertech 9018. GM's OLM said 78% remaining when I did the change.
Silicone is high as they mentioned..does the explanation they gave make sense? Should I be concerned at all about the nickel or the Maganese?
Little amazed that the sodium reading was so low especially as it has been reported that Mobil 5000 is the FF. Castrol 5W30 GTX is in the sump now...debating whether to do another change in 3K miles and make the change to Pennz Plat
Comments good or bad? I'm not familiar at all with the Ecotec or it's tendencies
