Avis Budget Group recently announced the puraDYN Oil Filtration System will become standard equipment on its North American fleet of nearly 300 heavy duty buses.

This equipment upgrade is expected to reduce motor oil use and oil-related bus engine maintenance by as much as 90 percent, and makes Avis Budget Group the first in the car rental industry to add an oil filtration system to its fleet of buses.

Implementation of the system follows a successful test on 15 Avis and Budget heavy-duty buses at Los Angeles International Airport (LAX) that demonstrated the environmental and cost-saving benefits of the system under actual-use conditions. The roll-out will begin with installation of the puraDYN system on the company's 30 additional heavy-duty buses at LAX.

The puraDYN system is a high-efficiency bypass filtering system that removes solid, liquid and gaseous contaminants from engine oil before they accumulate and cause damage. In the initial test at LAX, tests found that the puraDYN system reduces engine friction and wear, extends equipment life, improves fuel efficiency and helps engines run at cooler temperatures. The system also saves both time and money by reducing the number of oil changes required.
