Drag the sliders to match your operation — idle hours, days on the road, what you pay for diesel, how many trucks. The numbers update as you go.
$14,999 MSRP — financing available through Time Payment, so it can start paying for itself before it's paid off.
Common questions
About the numbers
How does the Green APU savings calculator work?
It estimates three things an APU saves you and adds them up: diesel you stop burning at idle (about 0.75 gallons saved per idle hour avoided), deferred aftertreatment/DPF service (about 60% of a $4,000 annual cleaning cycle at heavy idle), and the downtime those DPF service events cost you. Enter your own idle hours, driving days, diesel price, and truck count for a number specific to your operation.
How much does idling really cost per year?
A heavy truck burns roughly a gallon of diesel an hour at idle. An owner idling 10 hours a night, 320 nights a year, avoids about 2,400 gallons of that by running a Green APU instead — roughly $9,000 in fuel alone at $3.75 diesel, before DPF and downtime savings.
How long until a Green APU pays for itself?
At the default assumptions (10 idle hours a day, 320 days a year) the $14,999 Star Edition pays for itself in about 14 months. Drivers who idle more, or pay more for fuel, reach payback faster — often under a year.
Can I finance a Green APU?
Yes, through Time Payment. Because a Green APU typically saves more per month than idling costs, the unit can begin paying for itself before it is paid off.
