I am just at the end of one OCI now. I have an XG3600 on the shelf to try the next round. The 1MZFE has it's own issues, though...
I would caution you to pay periodic attention to the start-up noise on that engine with an over-sized filter, or really any filter. Every time I have tried to run an oversized filter (FL400S and one other I can't recall right now, not an XG) on this engine, I ended up with drain-back and dry starts after a few thousand miles. The filter location on this engine is really problematic with the horizontal orientation and proximity to the front header AND cat. My theory is the heat affects some ADBVs badly (and those that drained had silicone ADBVs). The extra oil in the filter may contribute to it, may not - not enough data to tell. I also run a large oversized filter on my SUV and it never has issues like this - but the mounting is at a down angle and low where there is lots of fresh air flow compared to the 1MZFE. Filters that last fine on this vehicle do not last on the 1MZFE.
So far I am having no drainback with the XG3614. But as it ages I listen more carefully. This engine is harder on filters than any I have ever had. But the engine iteself is great and runs like new (with necessary maintenance of course). It has 270+k on it now and runs wonderfully, and uses 1/2 to 3/4 qt of oil each 7,500k OCI.
So far so good in start ups. I've had no issues. The main problem with this engine is that it is hard to work on certain things. My rear exhaust manifold has a small fissure in it, and the 6 manifold bolts are rusted on badly. Multiple mechanics have told me that there is a near 100% chance that one of the six bolts with snap off in the head, and the head will need to be pulled just to replace the manifold.
Other than that, at 210k it runs great and uses no oil.
