Negative Positive
Title: It cleaned out my Wallet too, wish I had read this first!
Review: Picked up 2 bottles of this for my wife's Explorer which had a Rough Idle & she just filled up with Ethanol Regular.. . Didn't do a dang thing... Auto Zone claims I got a dollar off at 5.99 but if I look at the price above I got shellacked. Like the other reviewer says you can get 2 qts of TECHRON at Costco for 5.99 for fuel Injector cleaner. Thought I heard a Valve not seating right in my wife's engine. This didn't do anything to quiet that either.
Is the review positive or negative?
