21% INCREASE on 1st tank of gas after 3 tank baseline formulation.This tank had the initial 2 tablet insertion.This car went 370.4 miles on 16.885 gal.and uses high test gas.Baseline was 18 MPG.As excited as I am,I still marvel at the smoothness of the engine and just how good the car seems.I'll update further as I get more info.The 2nd tank will also be 2 tablets.
