I think I did see a blue topped 10w30, and yes, it wasn't certified, and not group III, good for 25K, guessing A4/B4.

Ahh gotcha on the XL. I wasnt looking at the grpiii so I didnt read into it much. Here is a question I'm not fully clear on: Does Toyota warranty require API cert or is this just a recommendation/guidance? I'm assuming the emission warranty requires the use of low saps so you have to stay with an SL/SM rating. But certification IDK ....

I thought it was pretty much common knowledge for the last 15 years or so that the oil had to be API approved, here in the U.S. ...and that's sort of been the problem at most of the forums I've been at over the last few years, a lot of people want to run the better oils, but they don't always have the API approval stamp on the front label.
