Life Cycle Costs Calculator
EnPak® Mechanic Series has many important benefits surrounding fuel usage and maintenance costs:
- Because EnPak runs with the truck turned off, it can lower fuel use up to 30 percent.
- EnPak's shared fuel supply delivers one tank to fill
convenience. - EnPak can significantly reduce expensive truck engine maintenance costs such as oil changes; filter replacements (fuel, air, oil, transmission); and wear on belts/hoses.
- EnPak can reduce truck engine hours up to 60% - significantly extending the life of your drive train.
The results are intended to illustrate the possible fuel savings, maintenance savings, and asset life extension savings using EnPak Mechanic Series and are based on user input. They do not constitute a proposal or a guarantee.

Fuel Savings
This is a simplified profile of a typical day on site. We have reduced it to three operating conditions. You can change the number of hours for each operating condition. Fuel consumption numbers are measured on actual trucks.
| Operating Condition | Fuel Consumption Rate (gallons/hour) |
Duration (hour/day) |
Savings (year/truck) |
|---|---|---|---|
| Truck: No load, PTO engaged | 0.57 | ||
| EnPak® Idling (1800rpm), Hydraulic pump engaged, compressor off, no load | 0.32 | 2 | $600 |
| Truck: High Speed, PTO engaged, no load | 1.10 | ||
| EnPak Idling (1800rpm), Hydraulic pump engaged, compressor stand-by, no load | 0.32 | 1 | $300 |
| Truck: High Speed, PTO engaged, full compressor output | 1.74 | ||
| EnPak Idling (3200rpm), Hydraulic pump engaged, compressor 34cfm @ 100psi | 1.09 | 2 | $2,044 |
Maintenance Savings
Significant reductions in truck engine idle hours and total engine hours will contribute to lower maintenance costs by extending the time between required maintenance intervals.
Conventional Truck Maintenance at Idle
| Interval (hours) | Costs (USD) | |
|---|---|---|
| Total Maintenance Costs at Idle: $1,689.06 | ||
