05 ES330 with 10-30 in it
have had syn. 10-30 in as that is what I had to use last time changed oil. I plan to run it down to about 30 degrees, then change back to the lighter wt 5-30. Thoughts about this?

I don't think you're going to see any real difference.
If you are using syn., it's going to have cling and cold temp. viscosity that will make it unimportant whether it is 5w-30 or 10w-30. Dino/mineral 5w-30 will likely give you less cold start up protection than full syn. 10w-30.
You car is back-spec'd by Toyota to 0w-20. If you have no oil consumption issues, you could run that this winter and see how it does.

i recently had oil change and added jsut 1 qt of quaker state full syn 0W20 and the rest with 5W30 Mobil1 oil..next oil change would be a 50/50 mix. am thinking of going to 0w20 or maybe just for the winter..will see..b
but so far no issues..and ya i did notice when pouring the 0W20 oil that it was soooo thin compare to 5w30

I've been running 0W-20 in both my RX & ES for nearly 2 years during the winter now, absolutely zero problems. The Sienna still gets conventional 5W-30.

It's not "designed" for it, but Toyota did back-spec the MZ series to run 5W-20 (official TSB). There is another chart floating around that claims that you can run 0W-20 as well.

Yup i know there are a lot of ppl on this forum who area using 0w20 BUT i think only during the winter. I dont think i want to completely switch over to 0w20 ..but maybe a blend of 50/50. But its good to know that you have been doing it for 2 years with no problems.

I don't understand why anyone would experiment with 0-w20, when Lexus calls for 5-w30.
Especially when the posters say that they have tried it for a few years and no harm done. Nor was there any benefit. So why risk it.
It should be noted that 0-w20 is so thin that it does not coat any of the moving parts for a long time, such as cylinders, pistons, bearings, etc.. After an overnight rest much of that oil would have gone back to the oil an, while a 5-w30 oil would still cling to the mechanical parts, preventing a dry start.
To each his own I guess.

"To each his own" would refer to whether one chooses to use the 20 weight or not. Which I agree, totally up to the owner.
But, saying a 20 weight causes more wear and doesn't protect/lubricate is absolutely absurd and misleading.
