26 bucks a gallon.
Full line means you shouldn't top off the coolant above the full mark when the engine is cold. Anywhere above that could cause an overflow when the engine is hot.
Go buy a gallon from Toyota and top it off to the full mark when the engine is cold.
Drive a car a few days and check the level again (when the engine is cold). If the level goes below where you topped it last, then you have a leak somewhere.

I have a GS430 and was worried about it for a while. Even though it is not on max level, it is a “sort of” a new default max level for us. I used to top it off every time I would see it but it would spitted out all extra fluid anyway. I’m sure that the extra fluid is being released from the top as I need to scrape off a mountain of pink “snow” from the top of reservoir after each top off. Also, driving on a hot day in the mountains was my primary suspect of the issue but it is not true; normal winter driving brings me to the same level again. Go figure. As long as there is some fluid in there, you should be OK. I still would like to hear an official Lex opinion on the subject though…

Brought the car in to take my SA up on his offer to top it up. They didn't have time, since I wasn't actually booked in, to really investigate anything but just filled it up and told me to keep an eye on it and they can investigate more if it drops between now and when I take it in for the fuel sensor tightening.
They took it in engine hot, and filled it up a finger or two past the "full" line. The SA sounded pretty sure that the full line is supposed to be the "hot" full and not a "cold" full. SA seems to think that the sound of pressure leaving slightly around the expansion tank cap is normal as well, but I'm not so sure.
Bottom line I guess is that it doesn't matter as long as it's somewhere between those two lines at all times. Now that there's more in there, I'll be able to easily gauge if it's disappearing somewhere or not over the next couple of months at least.
The dealership gets a gold star for taking it in just as a drop in and getting it topped up and back in my hands no charge in less than 5 minutes even though they were extremely busy.

The other day I checked the level in my car's resevoir tank right after I got home from work. It was about 5/16 inch above the full mark.
Some has a same thought like mine.

How about back pressure? My car is acting up. Replaced my thermo cause I was over heating. Now it's not overheating but constantly getting back pressure. And overflowing from that reservoir. The tank will completely drain, still not over heating?

Most likely bad water pump, common problem as they last 90-100k miles. Good thing there cheap, you can buy aisin brand (oem rebrand) for $80-90 off rockauto.com and takes about 2 hours to install. If you take a look behind the water pump pulley you should see pink slime, thats your coolant. If theres slime behind the water pump pulley then for sure the pump is going bad. Its also possible you are leaking out of the radiator, you should be able to see it as it drys pinkish powder.
