Mobil 1 EP 5W-20, 4176mi, 2012 Versa 1.6L

[DNVDMAX]

Here is my 2nd UOA from my 2012 Nissan Versa with the HR16DE engine. Lots of extremely short trips each day and plenty of cold starts. Refilled with the same lube even though it is spec'd for 5W-30. It was on sale for $3/qt. Maybe because it had water it? No seriously, the water is likely from the Arctic conditions and short trips and therefore ALS was unable measure viscosity.

ALS Diagnosis: All engine wear rates normal. Light concentration of
water present. Silicon level (dirt/sealant material)
satisfactory. Unable to obtain accurate viscosity result
at 100C due to presence of water in sample.
Action: Check for source of water entry. Resample next
recommended service interval to further monitor.

Obviously it's hard to get the oil hot up there. It's still fine and you should be able to extend your OCI just based on the wear #'s and TBN.

Silicon went up, how's your intake tract plumbing?

same with the iron. I am noticing todays semi syn oils are pretty good.

I have not paid particular attention to the intake in a while. This weekend I will take a look at the airbox and other intake connections. I installed a new filter in April and this summer was pretty dry up here. I put plenty of miles on this car on dirt roads. The new filter may have contributed as it was not loaded with dirt like the previous one. I will take pics if I discover evidence of unfiltered air making its way into the engine.
