i usually use techron, but the gas station by my house was out of stock, so i used STP's product instead. i scoffed when i read the label, "made with jet fuel". i put it in my gas tank anyway.

my car had an odd flat spot at about 3000 RPM's and the idle was rough. frankly, my car had all the symptoms of injector issues.

to my utter amazement, this stuff worked! my car runs perfectly after about 50 miles.
