Fuel Information and Data Sheets:
Here is a recording of detonation caused by 6 week old stale unleaded fuel. It is the “rattling” type sound behind the main engine noise.
Australian unleaded fuel can contain significant quantities of light volatile aromatics which boost the RON rating but they evaporate quickly. Some fuels can lose their rating in a matter of weeks, which can lead to detonation in your engine. Please read the data sheets carefully and avoid using unleaded fuel that is more than a few weeks old.
