Well, if they use premium in one test they use it in the other. The issue is the inflated EPA highway mpg of the CVT Impreza compared to all the others, who are tightly grouped. Strictly a mpg issue. If some do use premium it doesn't seem to matter. All the others are EPA highway rated 30 +/- 2 mpg.
Is it that the CVT Impreza was or is tuned specifically for Subaru's EPA test, without hills etc., or what is the reason it does so poorly compared to the EPA estimate?
