Is there any evidence, that is not provided by the fuel companies themselves, that this makes a significant difference in the lifetime of a vehicle? Because there's probably a point where it becomes diminishing returns. Bad analogy, but if you wash your hands with a squirt of soap and it gets clean, does it mean it will be twice as clean if you use two squirts?
Or if dumping a bottle of quality fuel system cleaner would do as well?
And exactly how much more is it beyond the minimum that is added that the fuel company won't say?
