Scotty,
I've got a 2009 Camery (170,000 miles) with that engine the drinks oil. I had a mechanic tell me he used "Engine Restorer" in another camery, and the problem was resolved. What do you know about this stuff? Is it worth trying?
Those kind of treatments generally work by thickening the oil, which can improve compression and reduce oil consumption a little bit, for a little while, in an old beater on its last legs. In no way do they "restore" or repair anything. That kind of snake oil has been around for decades. Might have been something to try on a worn-out '49 Hudson but I'd be very leery of putting anything like that in a modern engine.
If you watched Scotty's videos, those sort of fix in a bottle "cures" have to be done correctly to have the remote chance of working. Per Scotty, use with new clean oil for best results. Remember, it's a temporary band-aid solution that may or may not work in your car. If I remember correctly, I think the 4 cylinder Camry's from 2007-2009 were the "oil burners".
What brand? None of them will FIX your engine, but for $5-10, it might reduce your oil consumption - that's a pretty cheap experiment.
Glen, the brand name is "Engine Restorer". https://www.restoreusa.com/index.php
