I read that the burning wax and varnish are the major source of pollution and that is the ethanol is the added to help them burn properly, and distilled gasoline should be clear colored (not yellowish) and the filter is easy to make (big fuel filter filled with coconut charcoal powder and activated charcoal powder) . So if the filter works there will be no deposits in engine and the oil lasts longer interwals and this results in the longer engine life right?
