TJeeper...Ive been on this forum for quite some time now ( 2yrs ) and it has been verified that these 5.7's do NOT come with synthetic oil from the factory. Go to the Tundra forum and do a search on this to verify.
Thanks
Allrighty then...I got my info from a guy that manufactures the engine assembly. But what ever floats your boat.

All I thought I would give my honest expert advice...This is one area where I have some knowledge firsthand as an engineer in R&D for a major oil company and having spent several years in the lubricants division. First of all, you do not need a 0w-20, especially in warmer climates...because as the polymer additives (plasticizers) breakdown, you are left with 0 weight oil... Plus the wide range 0w-20...more plasticizers. Unless you are in weather below -22F, the extremely marginal results that you get with 0w-20 vs. 5w20 is not worth the added cost. In the worst case, the 5w-20 breaks down to a base 5 weight if you avoid oil changes and run extremely hard...Still you have some film protection once the engine reaches operating temps this is must better than a 0 weight oil.
Also don't believe the hype...I have tested and seen tests for almost every synthetic oil on the market today...the performance of these oils are all within 1% of each other. In fact, oddly enough some oil will perform better in some engines but worse in others. However, saying all that...I would highly recommend synthetics over "dino". being in Texas, I will stick with 5w-20. Since you can buy it in the 5QT Jug at wal-mart. ....and Mobil is not not the holy grail...they have a great PR and Marketing division though!

well if that's the case, then wesson oil is at costco , a 50lb drum for $14!!! just kidding
IMHO, syn oil is overkill if your going to change it every 5000 miles, but i do it anyways, due to the fact that toyota has 5w-20/0-20 is on the cap.
but that is some good info

I think I will run the 5w-30 for 5000 miles and then start changing the oil myself. Then, I'll have to decide which 5w-20 oil to run. Thanks for the replies.
