To serve customers dependably, transit fleets need engines that run reliably over extended intervals. That’s why they turn to Spinner II oil-cleaning centrifuges. It’s the most widely used bypass oil filtration device in the world – and it’s been used by virtually every major transit fleet in North America.
A Spinner II centrifuge does what a filter alone can’t: it cleans oil down to the sub-micron level and it literally removes soot and other contaminants from the oil stream. In the process, it preserves additive effectiveness and prolongs full-flow filter life.
The result is a level of oil purity that lets you extend oil service intervals and protects engines against wear better and more consistently than ever before. So you keep buses on the road longer and maximize long-term service life.

How Buses Run Longer and Last Longer
- Safely extend your oil drain intervals
- Save on oil and full-flow filters
- Increase in-service time
- Extend the life of engines and turbochargers
- Increase time between overhauls
- Reduce your operating costs
- Superior Oil Cleaning
