You would need to think logically.

I am looking to retire to Lisbon, fuel is $7.50/gallon there currently. My 5.3 liter powered 2016 Sierra gets 17 town, 22 highway - in a 6,000 pound 6'+ tall brick. The LS is 200 pounds lighter and churns out the same power as my mild 440 Pontiac (stroked 400). Best the 440 has got is 12 MPG. This a a KRE headed, ProFlo4 run mill.

The new LS/LT stuff is state of the art - the StratoStreak came out during Ike's presidency.
