I've used Blackstone for three of my oil changes. Gives you a good feeling when you go 10k on the oil and they give it a good report 
if you really want to get the most out of your oil, send a sample of used oil for analysis like Blackstone Labs.
You will get the breakdown of whats wearing in your engine, whether or not your oil is giving you adequate protection and a suggested oil change interval if your sample is consistent with your normal driving habits.
A standard test is around $25. Well worth the cost for piece of mind and possibly less costly maintenance down the road.

You're car is designed to use the 0w20w full synthetic oil. Like most manufacturers now you have a low friction engine built with higher tolerances and uses thinner synthetic oil. If you look in your owners manual, it probably reads as mine does that if that happens, change it again within 5 thousand miles with the correct grade and specs. You'll probably notice slightly less fuel economy with the thicker oil.
This topic has probably been beat to death, but going through some service paperwork, I noticed that on my first 10K oil change for my 2010 RX350 the dealer used 5W30, then the next time used synthetic. Are you subject to damage of any type by bouncing back and forth between synthetic and conventional, even if you're changing the oil regularly? I now have 38K miles and car seems to be running fine, but now I'm concerned. Thanks!

I am very curious of wear characteristics of the 5w20 and 0w20 oils that are out there.

Except for one dealer screw up, the 0w20w Toyota oil. Works well. I'm getting most of my oil changes done at the Toyota store. It's the same oil, but they don't take as much of my money .
