High Fuel Consumtion After Using COSWAY Fuel Saver

[adrianlek]

Problem solved. Bought a bottle of Gumout Fuel System Cleaner from Ace Hardware for $16.90 It claims 2 clean valves, injectors n fuel lines. Poured d whole bottle into d fuel tank + full tank of fuel n use as per normal. Car feels more responsive n consumption back 2 normal...

seriously... get off from all those products claiming to be 'fuel saving' devices, on stock engine or, especially when you have modified engines.
At least.. if you're willing to spend RM100-150 on these sort of device... it's better if you bought good sparkplugs like platinums or iridiums which actually CAN improve your FC for 1-2km per litre of fuel, especially long touring drives.

Very difficult to say. Could be faulty oxygen sensor due to chemicals from the fuel saver. Or worse faulty fuel injectors

Agree...
