What is the mpg expectancy of a '72 Buick Lesabre
OK- which engine? The Buick 350 2 barrel might get 20 MPG on the highway at 55 MPH- The 455 might get the same mileage as a Sherman Tank- why worry about it with a boat like this? It's a classic-
I had one back in 73 it got 18 to the gallon at 55 MPH
had a 70 455 coupe.. 12 mpg?! don't expect alot. it is 4 power.
