Xp3 Fuel Efficiency and Maintenance Case Study by Pepsi Guatemala
PEPSI Guatemala Fuel: Diesel
Test: Fuel Efficiency and Maintenance
OBJECTIVE Evaluation of Xp³ for Diesel’s effectiveness in transport units Nos. 950 y 945. Fuel consumption history, oil analysis, and injectors were checked before Xp³ was added. Oil analyses were conducted after 5,352 km, with and without Xp³. In addition, a detail record of fuel consumption (km/gallon) was kept for each unit. CONTROL PARAMETERS Oil Analysis: The engine’s internal parts wear can be determine by analyzing the used oil, and from there you can then determine the life expectancy of an engine. One (1) ppm is equal to one minute of wear in two years of an engine. However, not all the engine wear can be attributed to the fuel combustion. In this report the only ones analyzed were the ones who showed wear related to combustion: like chrome, soot, lead, oxidation, water and sulfur. Oil test analysis results: Wear on Parts per Million (ppm) Residual Without Xp³ With Xp³ % Difference Sulfur 53 28 -47% Soot 156 90 -42.3% Water N N N/A Chrome 25 4 -84% Lead 12 0 -100% Oxidation 83 76 -8.4% Fuel Filters A fuel filter’s function is to trap sediments, sludge, fibers, and water present in the fuel lines and tanks. The enclosed photographs show the fuel filters from the units before and after the use of Xp³. The first photo is from the non-treated fuel. This is highly contaminated. In contrast, the photograph of the fuel treated with Xp³ shows a drastic reduction of contaminants.
Consumption was verified by the bottling plant and the Xp³ distributor staff. Both agreed the unit number 950 had 15.72% savings while unit number 945 had 22.50% savings. For the purpose of analyzing the advantages, it was decided to use 9.49% as the projected savings. Projected Savings Analysis To project the savings we used two different analysis: a) Savings in fuel consumption b) Savings in maintenance Economic Projections a) Fuel Savings Diesel fuel used 40,000 gallons Quantity of Xp³ per month 10 gallons Gross savings 9.49% b) Savings in maintenance: History: Units 100 units When should the unit overhaul take place every 400,000 Km. Projected when Xp³ is used: Units 100 units When should the unit overhaul take place every 500,000 Km Life expectancy increased by 25% 20 months
