  Report on Mileage Review
 
Combustion Technologies (West) LLC
 

Combustion Technologies (West) LLC performed an audit on the fueling of the fleet of US Foodservice trucks servicing the Los Angeles region.

We received the daily fuel records for the entire fleet of US Foodstrucks servicing the Los Angeles region. The fuel records were maintained by an outside monitoring organization. Of the total 106 units, 62 units had regular operational fueling performed during the review period. These 62 units were the participants in the audit.

The fuel was supplied to the subject’s underground fuel tanks and dispensed at the subjects maintenance yard. Fuel records were maintained and accumulated by an independent fuel record keeping company based on the manual input provided by the fuelers at each fueling.

Review period was for the weeks ending May 5, 2001 through February 2, 2002.

During the 16 week baseline period, the fleet operated on commercially available diesel supplied by various outside fuel suppliers basically chosen for competitive fuel cost.

During the remaining 24 weeks, the fleet operated on commercially available fuel supplied by various outside fuel suppliers basically chosen for competitive fuel cost treated with Dipetane. The subject underground tank was treated with Dipetane at a rate of 1:200. Initially all of the trucks were individually treated. At each bulk fuel delivery, the underground tank was treated with a Dipetane dosage corresponding to the amount of fuel added. Except for the initial tank and truck treatment, all Dipetane treating was performed by subjects fueling personnel.

During the 16 week baseline period, the fleet averaged 5.0 miles per gallon. During the treatment period, a distinction became apparent at week 10 with a distinct increase of fuel economy. The initial nine week period of treatment has been divided up as the clean-up period. The remaining 15 weeks reflect full benefit of Dipetane.

The average miles per gallon are as follows:

Baseline
16 weeks
5.0 MPG
Clean-up Period  
9 weeks
5.3 MPG
6% Increase
Full Benefit Period  
14 weeks
5.7 MPG
14.4% Increase

Net increase from Pre Treatment to Full Benefit Period was 14.4%.

REVIEW PROCESS

Data received for review - initial data.

  • Forty-one separate weekly fueling reports of the La Mirada Based units for the periods from May 12, 2001 through February 2, 2002.

Sorted each of the files covering a 39-week period to include only the “power” units, which had the ability to use odometer readings for mileage calculation. The initial file contained more than 250,000 cells of individual fueling information.

Accumulated the fuel recorded per vehicle week by week.

Copied Unit #, Odometer reading and Fuel amount to a master worksheet.

The units were then manually aligned in the respective row.

Added “MILES” column, taking the difference between the target week odometer reading and the previous week odometer reading.

Added an “MPG” column, taking number of miles divided by the number of gallons.

Average was calculated at the bottom of each “MPG” column.

NON-PARTICIPATING UNITS ELIMINATED FROM THE DATA LIST

Out of the entire fleet, 62 units had comparative data during the entire test period. The remaining units were eliminated from the final review calculations.

The MPG figures for each week were transferred to the Summary.

CONCLUSION

The average miles per gallon are as follows:

Pre-Treatment
16 weeks
5.0 MPG
Clean-up Period  
9 weeks
5.3 MPG
Full Benefit Period  
14 weeks
5.7 MPG

Net increase on MPG from Pre Treatment to Full Benefit Period was 14.4%
