The first UOA, and my first DIY OC on my wife's 2007 Camry. It has the 2AZ-FE 2.4L slant 4.
Previous OCs were done at the dealership where I was told they use Toyota brand oil. They also put the Toyota oil part number on the invoice. The makeup oil was some extra TGMO 5W20 I purchased from the parts counter at the dealer.
I refilled with Castrol Magnatec 5W30 and toyota filter.
In the last 25k mile, I have noticed a significant increase in oil consumption. Typically 2+qts in 5k miles (to keep it a the "full" mark). There aren't any leaks on the ground, and I haven't noticed any blue puffs while idling. I've taken it to the dealer for the oil consumption test to see if it eligible for the recall Toyota has on the worn/stuck cylinder rings. I found out that the eligibility requirements for the recall is greater than 1-1.5qts in only 1000 miles!
I was wondering if the UOA would show anything that would point to worn/stuck rings, but it looks like nothing is jumping out even at this shorter OCI.
Some info I found suggested that a clogged PCV valve could lead to increased oil consumption due to blow-by. I checked the valve during while I was changing the oil. The PCV valve rattled when I shook it, but did look fairly dirty. I ordered a new PCV valve from Amazon, and will replace it soon.
Since I am doing my own OCs in my Tundra with the Castrol Magnatec 5W30, I decided to try and consolidate my oil weights and use the 5W30 in the Camry as well. I figured the heavier weight might help reduce the consumption. I am looking forward to see how the consumption is with the heavier weight and the semi-synthetic Magnatec.
