The SWRI /EPA DD60 series engine tests confirmed FP PLUS was able to decrease recorded BSFC -Baseline Specific Fuel Consumption by up to an average of 2.62% on test truck 520 and .75% on test truck 516.
Most interesting data from J1321 test was on 6 laps on test truck 520 each lap used less fuel than the lap before while the control truck was inconsistent as shown below. Fuel consumption is measured in pounds consumed.
