My t4r v6 sr5 4wd uses about 1 qt of oil every 5k oil change. 5.5 goes in 4.5 comes out. Nothing is out of place. I am a bit of an agressive driver. I have 190k on the clock. I use Mobil 1 5w30 and toyota brand oil filters. There is some oil left in these filters. That accounts for some of the oil but surely not a whole quart.
Thoughts?
