Test Procedure and Saving calculation

Which influences are at measurement ?

• Weather (rain need 8%-10% more fuel)
• Wind (about 8% more fuel)
• Way of driving (mood of the driver)
• Temperature
• Accuracy of notes
• Accuracy in filling up tank to have reference
• Driver take petrol for own purposes
• Different roads
• Traffic
• Same speed
• Same acceleration
• Same gear
• Load (5 ton need 5-8% more fuel)

How to do a test to exclude this influences ?

Do a 60 miles test under same conditions. No wind, no rain, no traffic and same speed,same load.

1. Fill up tank to absolute maximum to see it at the top of inlet.
2. Drive 60 miles with same speed and gear
3. Fill up tank to absolute maximum to see it at the top of inlet and calculate consumption,
4. Install  Fuelsaver Truck XL in the bottom of the tank
5. Drive 6 Tank fillings to clean engine
6. Fill up tank to absolute maximum to see it at the top of inlet.
7. Drive 60 miles with same speed and gear
8. Fill up tank to absolute maximum to see it at the top of inlet and calculate consumption
   
   Calculation:
   A good used to capacity truck will have follow calculation:
   Yearly Distance:     125,000 Miles
   Consumption:         6 Miles/ Gallon
   Gallon in a year:      20,833 Gallon
   Saving 10%             2,083 Gallon per year
   "2.5 US$ /Gal" =          5207 US$ each year in 10 years 52070$ !!!!
   
   So a XL-Trucksaver (1500 $) is payed back in 3.5 month at 10% saving and in 7 month at 5% !
