2011 Mazda2 10.5k mile OCI, 108k miles on engine

Oil filter was new at the beginning of the OCI. The last oil change shown on the analysis was after the oil filter had already been run for 7500 miles. Wear metals have definitely gone up, as has silicon. I believe it may be time to change my air filter.

Iron seems a little high. On the Camry it had a reading of 5 ppm after 10k miles a few months ago on 0w20 TGMO. Univ avg of 7 but that's based on 6600 miles.

Is this an engine with Direct Injection ?

Negitive on high iron.
The acceptable limit for iron is 150 PPM.

No, in 2011 the Mazda2 was still the old 1.5L ZY-VE. Low compression, multipoint fuel injected, 100hp. This engine is the generation pre-Skyactiv. Does anyone think the rising viscosity is significant? TBN is still good.

Oil probably running out of steam, would be my guess.

The oil thickens after typical shear thinning down to V-bottom, but I wouldn't be concerned really in this sample.

SatinSilver,
Why did you decide to change from TGMO to PP?
