What happens here
The presenter elaborates on the observed results, explaining that the residue seen on the plates (or lack thereof) directly corresponds to the quality and composition of the fuel. He categorizes fuels into four levels: standard pump fuel, non-ethanol pump fuel, engineered pre-mixed fuels (like TruFuel, Husqvarna, Echo, VP, RedMax), and alkylate fuels (Aspen and Stihl Motomix). He emphasizes that the 'dirty' residue is primarily due to aromatics (such as benzenes), which are chemical compounds present in varying percentages in different fuels. Alkylate fuels, specifically Aspen and Stihl, are highlighted for having less than 1% aromatics, leading to significantly cleaner burning.
Goal: Understand the chemical differences in fuels and their impact on engine cleanliness.
