Sage Oil Vac lube trucks can be spec'd with a large air compressor driven by a small gas or diesel motor. "The air compressor creates vacuum that is good for four to five oil changes, so the air compressor doesn't have to run continuously. This allows the lube system to be operated without idling the truck engine," says Seidenberger. "That's an important feature with today's fuel prices and diesel particulate filters on new Tier engines."
IMT systems are hydraulically driven. According to Worman, they're quieter, more efficient and have a higher rate of flow without having a large compressor to drive air.
In the end, Hayes suggests including your service manager in any decision about mobile lube equipment. "He's the one who is aware of the types of oils and quantities needed," he says. "He'll also be aware of any accessories that can be beneficial."
