Oil and Coolant Diagnostics for Diesel and Gas Engines
Oil diagnostics protect the longevity of your equipment
Is the wear on your engine within normal limits? How clean are your operating fluids? When should operating fluids, components, and wear parts be replaced? Our thorough oil and coolant diagnostics provide valuable insights into the condition of your engine, axles, transmission, hydraulic, and cooling systems. This helps prevent failures, improves machine performance, extends their lifespan, and ultimately increases overall efficiency.
Zeppelin operates its own well-equipped oil laboratory for oil analyses. Every year, trained chemists evaluate over 100,000 oil samples. Thanks to an extensive database, precise analysis and reliable comparability are guaranteed. Our experts often know more than anyone else because they not only consider the unit from which the sample was taken but also the engine type.

Key benefits for your organization
Optimization of Oil Change Intervals
Based on the results of the oil analysis, oil change intervals can be extended under normal operating conditions without compromising engine performance or protection. In heavy-duty conditions, oil change intervals can be optimally adjusted.
Condition Monitoring for Your Equipment
With regular oil diagnostics, you can always monitor the condition of your engines, transmissions, hydraulic systems, axles, and other essential components.
Efficient Maintenance Planning
Maintenance work can be better planned as the condition of the oil, and thus the engine, is closely monitored. This allows for timely maintenance actions and prevents unplanned downtime.
Damage Prevention Through Regular Laboratory Analyses
Through regular laboratory analyses, we can detect impending damage early, helping you avoid costly breakdowns and maximize the reliability of your equipment.
Oil Analysis Portal
As a registered customer, you can access all the results of your previous analyses at any time.

Coolant Analysis – Protection for your Cooling System

Coolant diagnostics are enabled through regular coolant fluid analyses. These analyses provide the most meaningful results and allow for a precise diagnosis of the coolant's condition as well as the cooling system. They help detect issues like pitting and corrosion early, while maintaining cooling performance.
