Fast and Reliable Fuel Dilution Analysis in Engine Oils

Fuel dilution in lubricating oil is a key indicator of engine condition, combustion efficiency and potential fuel leakage. Elevated fuel levels can reduce lubrication performance, increase wear and lead to costly engine damage. Accurate and timely monitoring is therefore essential for preventive maintenance and condition-based servicing.

The GAS Fuel Diluents in Lubricating Oil Analyser provides a fast and reliable GC-FID solution for quantifying diesel fuel content in engine oil samples. Based on ASTM D3524 principles, the method uses backflush technology to remove the heavy oil matrix from the analytical column, significantly reducing analysis time while maintaining accurate quantification. This enables high throughput analysis with excellent repeatability and minimal operator intervention.
