So has anyone gone to synthetic and do oil changes yearly?
I only drive about 5k miles a year, been thinking about switching to synthetic and doing oil changes yearly instead of every 6 months. The ~4 hour visit to the dealership is getting really freaking old. And prices have continued to go up which is pissing me off too.

Why are you changing your oil every 6 months? That's excessive even if using conventional oil.

The owner's manual doesn't say 6 months, 6k miles or anything about time or distance. All it says is you'll have an indicator come on when it's time to change your oil and that all depends on how you drive your car and at what point the light will come on. My own choice is 6k miles or annually whichever comes first. For warranty purposes guess you need to change it when the light comes on although you can reset it whenever you feel like it.

The maintenance indicator light is based on miles, not time/months.
Y'all can do whatever you want. It's all manufacturer "suggested." Personally I think overfilling the oil or using the wrong oil viscosity is a bigger issue than deciding 6 months vs 1 year. Those mistakes have greater potential to damage your engine almost instantly if you push the car hard.

What exactly happens to oil when it sits? How does it break down? I own many cars and spend a small fortune on oil I change them all every year even if the car is not driven. Not scientific but the oil LOOKS like it just came out of the bottle.

Go to drivers.lexus.com and check. They list it under maintenance. It's also in the maintenance schedule in the manual.
I have done yearly oil changes on the ES, RX, GS, and LS, but they all require 10k/12 month changes. I kinda want to try it in the IS and see.
I wish somebody cool at Lexus would confirm its ok if I contacted them. I would bet there's a 99.9%chance I will get the generic "follow the manual" answer though. One of the Corvette engineers used to post a lot and answer questions on the forums, Lexus needs a guy like that too.
