2012 Camry 2.5l 142,961 miles 3k OCI In /Out: Valvoline Restore and Protect 5W-30 / STP XL

Ran across an easy OBD2 test for the AJ133 that will give an indicator of timing chain stretch. Not sure if the cheapest OBDs can read the $06 codes, but an inexpensive HF MR10 worked for me. These values represent the amount of VVT correction (in degrees) and will grow as the chain stretches...

Thanks for the pics. I'd be guessing 20k not 220k, pretty crazy.

2012 camry se 2.5l here - first 130k on 0w-20. Went thicker 5w-30 last couple OCIs (Valvoline Restore and Protect). 5w-30 might have smoothed out my idle a tiny bit (balance shaft noise common on this engine) ... possibly placebo. Will be sticking with 30 weight, but this engine doesn't...

The BMW spiel suggests a reference against a standard to as the trigger. What can these dielectrics sensors actually monitor - is it a conductivity test? Does that mean PH and/or metallic solids, perhaps?

Most OLMs are a math function of engine hours / environment / load, not physical sampling. Like a slightly fancier version of "next change in 3k" sticker. https://bobistheoilguy.com/forums/threads/olm-accuracy.276522/

I want to believe .... but my oil levels stay too darn flat to think enough makes it through the pcv system to the intake valves. Maybe leaky valve guides could help here haha.

In similar situation - inherited a 2012 SE from mother in-law - dealer serviced, now approaching 137k miles. I've used all three 3 Valvoline Restore and Protect grades (0W-20, 5W-20, 5w30) in this car, can't tell a difference (Los angeles climate). Oil consumption is/was near nil, though ... i...

theres a YT video about your question - response from Valvoline - seems like seal conditioners of the normal level, but not to the higher levels found in High Mileage oils.
