Petrol being more refined than Diesel have less by-products. It still faces the AGING process of fuel deterioration which will cause sludge build up on the engine when combusted in the chamber. This sludge will make sure that not all the petrol are completely burned hence causing emission pollution from the engine.
What POWER-DMPS does is to INCREASE OXYGEN molecules in the combustion chamber which we know will make sure the burning INTENSITY to increase which means most if not all the FUELS are burned off.
Power Petrol is AIMING at COMPLETE burning of the petrol fuel to produce pure H2O vapor instead of the emission pollution of Carbon Monoxide (CO) and Hydrocarbon (HC).
