Thank you both.

I just bought a 06 lx470 has just over 100k . I am having the timing belt and water pump replaced and asked the mechanic to change the oil .He keeps insisting that I find out the exact type of oil. I bought it from a Kia dealer they told me it was a blend. I called the lexus dealer from the name on the sticker indicating the next oil change mileage. I get two different answers. Forums say synthetic 5 w30. Does anyone know what is recommended? Also, if I just tell them synthetic and it has been using a blend will this hurt my car. Thanks!
