Part of maintenance requires that we use good quality gasoline with cleaners in them or if we can't access this then we must separately treat our engine.
Some say that cleaners are absolutely useless, some say they leave deposits, etc....
What has your been your experience? State the type of car, engine type, name of the cleaner and your experience.
I'll tell you mine. I drove a Toyota Corolla Altis for a few months and in the duration that I drove it, I used the Gumout Fuel System Cleaner every 3 months. This fuel system cleaner did wonders for the little 1.6l 3zz-fe engine as not only did the car perform much better, it idled a bit smoother and gas mileage was a lot better as prior to treatment, it struggled to break 300kms when the fuel gauge read at the last 1/4. After using the Gumout once, gas mileage went from a struggling 300kms to 350kms at the exact same final 1/4 tank of gas. The car also performed a lot better.
I purchased a Valvoline NitroShot after reading while in store that it contained PolyAmine which is supposed to be a better cleaner for the engine. I am not an expert but I really felt that this cleaner made a difference. I poured it into the fuel tank and shortly after noticed a little more low rpm power. It even helped to smoothen the idle by a considerable amount. However, on that particular tank of gas, the injector cleaner made a difference more than usual, I'm unsure as to how that happened...
From my research and further testing, I've realise most of these off the shelf products are mainly marketing gimmicks. Some do help with minimal performance gains which aren't placebo but its really nothing to talk about and cannot ever be a fix for if you have issues with your fuel system.
