Does it work even after 2.5 years of using cheap gas? Never had any problems with the car, but I changed my exhaust 2 weeks ago and also filled the tank with Chevron. The funny thing is, I seem to be getting a better mpg on this tank and I don't know whether it's the exhaust or the gas. It's probably both

So, back to my question, will using better gas clean the injectors over time or should I use something else? And if so, what should I get? Anything from the gas station or is there some secret power potion?
