Oil Cleaning Centrifuges For Fleet Trucking
Spinner II oil cleaning centrifuges help diesel truck fleets and owner-operators control soot, extend lube oil service intervals, and reduce oil-related maintenance costs.
Installed alongside the full-flow oil filter, Spinner II keeps engine oil cleaner so trucks can spend more time in service and less time in the shop.


Cleaner Engine Oil for Fleets: Managing Cost, Uptime, and Engine Life
Fleet trucking maintenance teams balance oil cost, filter service, labor availability, engine protection, and vehicle uptime. Low-emissions diesel engines can generate high soot loads, while stop-and-go routes, long duty cycles, and extended trade cycles increase the importance of maintaining cleaner oil throughout the drain interval.
Spinner II provides high-performance bypass oil cleaning for diesel engines. It can be specified on new trucks or installed on existing engines, giving fleets and owner-operators a practical path to improved oil cleanliness and lower oil-related maintenance burden.
Operating CHALLENGES
Soot and Fine Particles Increase Fleet Maintenance Burden
Oil contamination can quietly increase cost across an entire fleet, especially when service intervals, oil purchases, filter changes, labor hours, and engine wear are multiplied by every truck in operation.
- Soot loads generated by modern low-emissions engines
- Waste oil and filter disposal costs
- Fine particles that contribute to engine and turbocharger wear
- Oil and filter changes that consume labor and reduce truck availability
- Inconsistent oil cleanliness across the full service interval
- Difficulty validating extended drain decisions without oil analysis and cost data

HOW SPINNER II HELPS
High-Performance Bypass Oil Cleaning for Diesel Engines
Spinner II centrifuges are used in addition to the full-flow oil filter. The centrifuge removes contaminants from the oil stream instead of allowing them to accumulate on a media surface, helping maintain consistent cleaning efficiency throughout the service interval.
The technology is designed to remove damaging fine particles, including soot particles, and provides high contaminant storage capacity. For fleets, that combination supports longer oil and filter life, better engine protection, and simplified maintenance planning.
The operational value of cleaner oil increases when benefits are applied across a fleet or a high-mileage owner-operator application.
- Reduce oil, filter, labor, and waste disposal costs
- Lengthen service intervals when supported by oil analysis and supplier/OEM guidance
- Prolong full-flow filter life and preserve additive potency
- Improve engine and turbocharger protection by maintaining cleaner oil
- Maximize in-service time by reducing oil-related maintenance events
- Support long-term preventive maintenance and potential resale value through cleaner engine operation
