Re: Fuel injector cleaners
I run Techron Plus Concentrate through mine now and then, but it is mostly to make my fuel level senders happy.
I make sure I only park the car for extended periods with non-ethanol fuel in it. Ethanol has this annoying ability to separate over time and leave you with 3 distinct layers of liquids in your fuel tank. Water, Ethanol, and gas. Since the water sinks to the bottom, your car gets to suck it in first.
I swear Ethanol was created as a stimulus for mechanics.
