Some maintenance issues and associated towing charges are irregular and difficult to calculate. A clogged particulate filter means added shop time, towing and downtime for the truck. The i-phi™ can help. A cleaner engine operation, means a cleaner fuel burn and cleaner components that are less likely to fail.

On the other hand, fuel costs are fairly constant, at least until the next increase in price. You have a base line. You know what it's costing for a specific run based on an average mileage and the cost for fuel. We've taken some of these averages and calculated the quick ROI based on fuel economy alone...
