Don't fill your tank with 89. The IS350 (and 250 for that matter) are high compression engines. High octane gas serves one purpose and one purpose only... to resist detonation. Detonation is uncontrolled combustion (i.e. small explosions in the combustion chamber when they're not supposed to happen). This breaks things.
If you do accidentally fill up with a lower octane, drive the car very easily until there's enough room to squeeze some more 93 in it. The ECU will pull as much timing as it can to keep detonation in check, but knock sensors aren't perfect.
You'll basically find this information in less detail in your manual.

Don't be worry about it. Just a liltle amount won't hurt anything. But if it's $0.11 worth of water into your car then it will be a big problem. jk.
Enjoy your car and don't worry too much.

Since no one on this list seems to believe a damn word I say, despite their self confessed lack of knowledge and their unfathomable need to spread disinformation, I think I'll take my leave now.
But before I do, I'll leave you this parting tidbit:
Manual Page 384:
If premium fuel is not available, you may use unleaded gasoline with an Octane Rating of 87 or so (Research Octane Number 91).
IS250: The use of such gasoline will cause persistent heavy knocking. If severe, this will lead to engine damage.
IS350: The use of such gasoline may cause the engine to knock or drastically reduce output to protect itself while driving with a heavy load. To avoid this, refill the tank with premium unleaded gasoline as soon as possible.

You can fill your tank with 87 oct regular and not hurt anything except the performance. The car has knock sensors that if they detect knock/ping the retard the timing. Not likely you will hurt anything. The amount you are worried about is just fumes.

Did you know, that if there is only one handle per pump, then you will get about 1 gallon of whatever was previously pumped.
That sucks! So if you pull up to a pump where someone last used 87, you will get 1 gal of 87. When you leave, whomever drives up next will get 1 gal of 93.

Honestly, no offense, but I can't even believe that someone would even post a thread about 11 cents worth of gasoline. What is that like 10 drops?
And the entire thing about octane and detonation is a load of crap. Even over the long term. As long as it is higher than 80 (which I don't even think you can buy) it isn't going to do anything to your car. I understand the philosophy behind higher octane and detonation, but until I see proof that a car exploded becasue of it, you can run it on any grade gasoline you want.

As for where to get 93, I get it at Sam's Club.
