Still..you think after 20 years later, you would think these newer engines are supposed to be more power efficient, especially when the SR20DE engine had like 30MPG on the freaken god dang Sentra!

Not disagreeing with anything you said, just pointing out the SR20DE is a 9.5:1 compression which is an important factor to remember as well. |
It could be possible for them to have 2 maps programmed, one for premium and one for regular. If Ford could do it on my 93 Lightning, I don't see why manufacturers can't do it now.
Another thing to consider about efficiency is the cars 20 years ago were generally lighter as well.
