Don’t let oil changes interrupt your schedule
Transit bus and truck engines produce greater amounts of both solid and liquid contaminants due to continual stop-and-go schedules. These engines typically run hotter and oil becomes contaminated much faster resulting in more frequent oil drains, but what if you could keep your oil clean instead of changing it? puraDYN systems will keep engine oil constantly clean while in operation, dramatically extending the time between oil changes by thousands of miles. Simply put, if the oil is clean and additives are maintained, it does not need to be changed.
Since 2010, Lima International Bus 1SA in Peru has been using the puraDYN system on 130+ buses with Cummins natural gas engines and credits puraDYN with an 86% reduction in oil consumption vs. engines without puraDYN. Additionally, they have experienced a significant reduction in wear levels in both engines and transmissions that benefit from the puraDYN system.

"We calculate that we've saved over 60,000 gallons of oil.
The engines remain clean and
perform at peak level.
We've also performed extensive fuel consumption measurements
and consistently achieve a 2% - 3% savings in fuel."

Proven by the U.S. Department of Energy (DoE)
A three-year evaluation (2002-2005) of bypass oil filtration technology was conducted by Idaho National Laboratories (INL) for the US DoE’s Freedom Car and Vehicle Technologies Program. The puraDYN system was selected as the test manufacturer for the duration and used on eleven four-cycle diesel engine buses accumulating 982,548 test miles.
Of a total of 72 bus engine oil servicing events occurring during the evaluation, 64 oil changes were avoided by using the oil bypass filter systems. The 64 avoided oil changes mean 2,164 quarts (541 gallons) of new oil was not consumed nor generated as waste oil. This equates to an 89% reduction in oil use and a concurrent 89% avoidance of waste oil generation.

Since 2010, Lima International Bus 1SA has utilized puraDYN filters on 81 articulated and 56 feeder buses. The articulated buses have been driven an average of 558,000 kms with oil change intervals extended to 78,000 kms while the feeder buses have been driven an average of 800,000 kms with oil change intervals extended to 132,000 kms. This represents an 86% reduction in the use of motor oil.

“Nabors’ use of puraDYN filtration systems to continuously clean engine oil has reduced our need for oil changes by over 80% and eliminated the need for most mid-cycle, top end engine overhauls.”
Siggi Meissner, President, Global Drilling & Engineering | Nabors Industries
“Installing puraDYN systems on our entire fleet is one of the most beneficial cost vs reward decisions I have made in my career to date.
We are not only saving money on oil by safely reducing oil changes, but more importantly, we now avoid losing 1-2 days per month of downtime to complete an oil change.”
Monte Madsen, Sr. VP | Legend Energy Services
“We have been able to safely extend our oil drain intervals to 5,000 hours from our previous practice of 1,000 hours. It’s a win-win for our customers, the environment, and Scandrill.”
Paul Mosvold | President & Chief Operating Officer | Scandrill
“Based on my prior experience with Puradyn, I am excited to equip the entire Campbell Transportation fleet with their oil filtration systems and safely reduce the frequency of oil changes on our engines and generators. Keeping our oil and engines cleaner will reduce downtime and maintenance costs for Campbell.”
Michael Pilgrim, Manager of Vessel Maintenance | Campbell Transportation Company, Inc. | Houston, PA
“Puradyn offers the best solution for keeping engines clean, safely extending oil drain intervals and reducing overall life-cycle costs, protecting substantial investments in the commercial marine and industrial industries.”
Harry Lartigue, Jr. | MnI Diesel | LLC Houston, TX
"It enables us to extend the oil drain intervals from our old standard of 250 hours to 3,000 hours. This equates to a savings of 354 gallons of oil or $3,210 per year. another boat in our fleet has been able to exceed 65,000 hours prior to overhaul."
Captain Bill Clark | South Ferry Island | Shelter Island, NY
“While the puraDYN system quickly paid for itself by extending oil life to over 3,000 hours, its real value has been extending the life of our engines from running on continuously clean oil. It’s like an insurance policy for our engines.”
