Schaeffer 5W3 SM, 6328m, Oct03 Sentra 1.6L

[dm]

Thankfully, Si has gone done significantly, probably due to new air filter. Wear figures seem to have crept up but this run was 35% longer than the previous. Report says no glycol but I find the Potassium 12 and Sodium 6.4 a bit disturbing ...

I'm puzzled about the sulphur readings, I have seen other Schaeffer UOAs here and they are no where near the levels in my sample. Could it be from the fuel ? I was running mostly on local brand SPC RON95 fuel for latest 2 samples. For 13Nov sample, it was mostly shell RON95

The neo-magnets on the oil filter could have interfered with the iron reading.

Any other comments ? Thanks

Amazing to me is how little oil this engine holds...not even 3 quarts! Schaeffer's did well. Once again showing it can go the distance.

I agree..keep your eye on it.

Aluminum is climbing, so maybe there is a small coolant leak.

I really hope it's not a coolant leak cos this seems to be a fairly common problem in QG18DE engines in the Sentra in the States due to head leak according to:

I will follow AL's advice and keep an eye on the coolant level and do another UOA at next oil change.

Thanks.
