Looking at the manual for the car, the picture example shows a picture of the donut which has the API, the grade and the Energy Conserving II on the bottom. I can't seem to find that in auto stores. Does it exist? or is it just hard to find. By the way I drive a 02 VW Jetta GLS 2.0L which i only get around 16-19 MPG. I don't expect very good fuel economy but it should be better. Currently using Mobil 1 5W-30. Hope that by using Energy Conserving II it could improve a little bit.
