GS4 130K Safe to switch to Synthetic?
I recently purchased a 2000 GS400. I would like to start using Amsoil in it, but i'm concerned because the mileage is high. Any thoughts are appreciated.

depends but it shouldnt be bad.. if it does leak then just fix it.
Obviously if it starts leaking cuz of the switch then it woulda leaked over time anyways. Better fix it now than later.

go on lexus.com and input your VIN in the vehicle thing to see pass records from Lexus.. it gives you an idea at least.

That's totally incorrect.
It's a leftover old wives tale from the days when Synthetic oils were a new product and being put in ancient cars.
Let me put it this way, if you car is being held together by sludge the Synthetic Oil may, over time, break down enough of the sludge to expose the gaskets to fresh oil. If your gaskets are ****ty cork like in the old American cars with large part tolerances, then it'll probably leak.
On your Lexus 130k miles and the engine isn't even at it's halfway point. The tolerances are all much closer, and the gaskets all started out as a higher quality material.
The only thing Synthetic will do is flow easier and quicker in the mornings. Which is especially important during these cold winter months. This will reduce some engine wear at start-up.

Also, on teh subject of sludge. If you think your car's engine may have some sludge buildup you want to clean it out slowly, not all at once.
A way to do this (like my old Tacoma was) is to use Synthetic oil plus a single quart of diesel oil every oil change. And change the filter every 1500 miles. Diesel oil has alot more detergents than regular oil, and will break down the sludge. Only one quart because you want to do it slowly.

My synthetic oil experience
I started using synth in my GS400 at 127,000KM when I bought the car - now 160,000KM - No problems.
I switched my 91 Sunbird to synth at 395,000KM - No problems
I switched my 2004 Malibu to synth at 130,000Km - No problems
I switched my 90 Cressida at 114,000 KM - No problems
I think you're safe
