Impurities, both in diesel and gasoline, corrode and compromise the injector nozzles of the engines.
Engines may suffer from excessive fuel consumption because the fuel will not burn properly. At the same
time, performance will be worse. And there will be a tendency for all fuel nozzles to rust, with risks of
clogging the fuel flow and preventing the engine from running.
Therefore we recommend:
