here are few pics of spark plugs replaced NGK PKRE-6EGP, experts please comment on fuel consumption, 1600CC 16Valve EFI SOHC within City driving on PSO FUEL
looks normal but how old they are?Also post pictures after cleaning because there is some glazing on insulator area which occurs at high temperature.
wat about usage of fuel additives??? for example STP fuel system cleaning agent??? can they lead to rust color of spark plugs???
don't know but plugs are looking too old.
they are perfect if you not the optimum performance but optimum fuel mileage
^^ thanks..
its returning 270~280 kms on Rs 2000 fuel...i guess this is best i can get albeit i can stop myself from doing rabbit runs till 120 then put my foot of the peddle.
BTW im back to OEM copper plugs
