ProFuel ^X-2® Fleet Test Protocol

Number of Vehicles:  10

5 control vehicles – 5 ProFuel ^X-2® Fuel Conditioner treated vehicles

Step 1:  Select 10 vehicles with same engine type, comparable miles since last overhaul, and similar operating conditions. 

Step 2:  Take used oil analysis samples from all 10 vehicles.  Used oil analysis test to be conducted (full package) to diagnose engine condition in all vehicles.  Analysis intended to ascertain engine operating condition prior to commencing test. 

Step 3:  Upon satisfactory completion of analysis in Step 2, divide vehicles into “control” and “ProFuel ^X-2® treated” vehicles.

Step 4:  Change engine oil, filters, air filters, etc. performing standard maintenance and assuring all engine settings (including injectors) are at manufacturer’s spec. 

Step 5:  Provide each driver a log noting basic information including gallons of fuel added, engine oil added, and driver observations concerning performance, smoke, and overall engine performance. 

Step 6:  Fill all fuel tanks to top of neck.  This is required in each fill-up to accurately measure fuel added at each fill-up. 

Step 7:  Conduct baseline tests consisting of approximately 2,500 miles per vehicle per week.  No ProFuel ^X-2® fuel additive added to any vehicles. 

(a)    Each driver provide log and credit card slips denoting fuel added each fill-up,

(b)    Upon return of each vehicle to terminal on weekend, fill fuel tanks to neck, complete weekly log;

(c)    Take used oil analysis sample and submit to laboratory for full analysis;

(d)    Baseline test repeated over 4 week period. 

Step 8:  Review mileage results each vehicle as well as used oil analysis reports.

Step 9:  Change engine oil, filters, air filters and check each engine to ascertain and where necessary, re-set all settings to manufacturer’s spec. 

Step 10:  Add ProFuel ^X-2® to the diesel fuel of 5 of the 10 trucks and repeat each of the above baseline steps in all 10 vehicles.

Step 11:  Comparisons:

(a) Compare fuel economy, oil consumption and used oil analysis reports in the baseline tests for the control vehicles to the after-test in the control vehicles.
(b) Compare baseline test for the ProFuel ^X-2® treated vehicles to the after-test in the ProFuel ^X-2® treated vehicles.
(c)  Compare change in the fuel consumption (mpg) and oil consumption between baseline and after-test in the control vehicles to the change in fuel consumption (mpg) and oil consumption in the ProFuel ^X-2® treated vehicles. 
(d) Make above comparisons reviewing used oil analysis tests to determine any trends in wear metal analysis, fuel dilution analysis, total base number analysis.
