Thanks for the swift explanation !

Thanks for the valuable information you provided. By the way, (I have heard it before) why it should put an additive only before an oil change??

Thanks for the replies. I asked about "Fuel System Cleaner" which can be put directly into fuel tank. not the injector cleaning spray ...sorry for my misleading massage (I corrected it).

HI; What is the most effective Fuel System Cleaner fluid available in the Sri lankan market ? Isn't "Chevron Techron fuel system cleaner" available in SL now ??? RG
