I'm running Castrol 5-30 right now thats because my car only has 800 miles on the odo.

Once my car hits 10-25k miles then I will switch to full synthetic either Mobil 1 or Castrol Synthetic.

I'm running Mobil 1 5W-30. Changed it at the 10,000 mark. Next oil change coming up in the next 2500. Any benefits for 5W-20?

If you change your oil often enough, I've found there really isn't any need to go synthetic. I ran normal dino oil in my S2000 for years and never had any problems. Plus unless you are going to track the car, the oil will never be really abused to the point where the synthetic protection would be worthwhile.

If I remember correctly, 5W-20 is the new recommendation from Lexus.

My oil cap says 5w30 not 5w20.. Mobil Full Syn

The new recommendation is 5w-20.

Lexus corp. released it.. and someone posted it, anyhow.. I just recently talked to my service tech to get oil filter number and oil to be used and he said 6.7 quarts of 5w-20.

That's because the recommendation was changed after your car was manufactured. See Lexus TSB EG006-06. 5W-20 is now factory fill and recommended for best fuel economy and cold starting performance. 5W-30 is also a perfectly acceptable oil, and it's what many dealers are still using.
