Hello does anyone know if Fuel additives really do work,? specifically detergents. Is there a detergent on the market that you can add to your fuel that would act as a clensing agent. I was told by a technician once that buying the cheaper gas (which has a higher conentration of Sulpher) is not that good for your vehicle in the longrun, or is it just a cash grab for the oil companies/ Vehicle manufacturers. thanks
