It weighs 4500lbs, it’s not THAT much lighter and has more power by far.

It’s a 2014 caprice.
I changed the air in the tires on my blown 02 Denali and went from 9.9 to 10.0 mpg so anything’s possible. 
From my experience most of your mpg gain could be coming from the air filter. When I purchased my 04 Burb 3 years ago just changing the stock air filter resulted in a 15-20% gain in mpg. The PO lived on a dirt road and the filter must have been well clogged with tiny dust particles that you couldn't even see. Since then it has remained steady at about 16 hwy 13.5 city.
