Synthetic Oil
Question
Can I use synthetic oil in my Toyota?
Answer
Synthetic oil may be used if it meets all specifications provided in your Owner’s Manual. Toyota is currently recommending API1 grade SL “energy-conserving” or ILSAC2 multigrade petroleum-based engine oil3 for our vehicles. (The “SL” designation supersedes previous categories such as “SJ” and “SH" and thus can be used in vehicles requiring SJ or SH motor oils.) In moderate climates, this oil should have a Society of Automotive Engineers (SAE) viscosity rating of 5W-30*.
If you decide to use synthetic oil for the engine, it is best not to switch until the first scheduled oil change. Synthetic oil should meet the specifications provided in your Owner's Manual. Even if synthetic oil is used, we do not recommend a longer oil change interval. Also, once synthetic oil is used, you should keep using it and not switch back and forth with natural petroleum-based oil.
While synthetic oil may offer some benefits, in our high mileage tests with preventative maintenance performed at the recommended intervals, petroleum-based motor oil has provided excellent service at a reasonable cost. All Toyota vehicles come from the factory with petroleum-based engine oil.
The Toyota New Vehicle Limited Warranty does not cover any damage to the engine resulting from the use of engine oil that is defective or that which does not meet the specifications provided in your Owner's Manual, regardless of whether the oil is natural or synthetic.

At least Toyota has their head pulled out when it comes to long change intervals with synthetic. It is funny how the oil manufacturer will tell you up to 15k on some oils, but the car manufacturers, good shops, etc will say the opposite!! I will stick with my own knowledge and the knowledge of those not trying to sell their own oil!! Funny how the long change interval stories fail to mention all of the combustion byproducts and condensation that builds up REGARDLESS of the type of oil!! I use Mobile1 synthetic, and change a little longer than with normal oil, between 4-5k. That is as far as I will stretch it.... I have seen engines running on synthetic, changed every 10k miles like the oil company said for long periods... way more sludge than should be present!!! Plus, you can never change your oil too often as far as engine life is concerned!!!
Just hit 1000 miles and put in a K&N gold filter and Mobil 1 full synthetic. That stock toyota filter was sure tightened like a ****. I needed some big channel locks to loosen it. 
I love how easy it is to change the oil on a tC. Mine is lowered over 2 inches and I don't even have to jack it up hehe. Good engineering IMO.

Anyway, I've been an AMSOIL dealer for a few years, so you can probably guess what I use. I'm just under 650 miles on the box, gonna change it with dino oil at 750 and 1500, then switch to AMSOIL with an extended drain interval after that. I'm still debating on the interval that I'll change at. Even though I'm a fan of extended drain intervals, I can't bring myself to go beyond 12,500 miles, even when AMSOIL rates the oil at 25k or 35k.

You are missing the whole point of synthetics ... The point of synthetic is so that you can extend your drain intervils SAFELY ... Do you like people like Mobil and Amsoil would preach 15k-25k miles changes if it was gonna hurt you. I spoke to my ExxonMobil rep when the new Mobil oil came out they spent Millions of dollars and years of reaseach before they said 15K on Mobil 1 Extended Performance ... Im sure Amsoil did the same before they said 25K ... the byproducts you are talking about are nothing ... your oil filter cleans out most of the junk in your oil ... You should just save you money and run a semi-synthetic ...

I dont think you fully understand Synthetic Oil ... There are WAY MORE cleaning addtives, and antiware additives that lets the oil go longer with no harm ...
