Does a DIY rapid oil test from the internet really work?
Year of publication: 2026
Various manufacturers offer quick tests for lubricating oils on the internet. They claim that a single drop is sufficient for an oil diagnosis. The test result shows whether the oil is still fit for further use or needs to be changed. They also claim that any damage can be detected at an early stage. But is there anything to these promises?
