If it had a Buick 3.8, it would get at least 27! My 2002 Park Avenue got 29.

Unfortunately it’s not only fuel economy but emission regulations. Those have increased even more so that fuel economy regs over the last 20 years.
GM had no choice but to end the 3800 in 2007 because it had gotten to the point it was impossible for that motor to meet ever increasing emission regs. That’s why the 3.6 was brought up - it’s not much better on fuel but far more emission compliant.
You should see the mess diesel guys have on their hands now. $10,000 worth of DPFs, a billion oxygen sensors, sophisticated, complicated, and expensive exhaust systems, and of course the DEF additive. If you don’t maintain a diesel to a T, changing the oil really every 3,000 miles no matter what, and not letting it sit and idle long (it’s a diesel - they used to be made to do that) you’ll have $10k in repairs that AREN’T the actual engine issue.
