Had a Service Fuel System Error code. Fuel Guage dropped to Empty & stayed there. Used a double dose of Techron & it cleaned my Fuel Sending Unit. It supposedly gets gunked up on the fuel level contacts with Sulphur contained in fuels. A day later Guage came back & error cleared.

Not as pictured online. Ordered online and picked in store. Received old Techron products. Was shocked that the outside of these bottles are quite dusty with residues, and full of scratched marks. As well, the advertisement on the neck of bottles claimed new look, but that was from an old advertisement campaign. Hesitant to put this stuff in my car, so went to another store to verify what a new bottle of the same product should look like, and sure enough it's new and with a different advertising label on the neck of bottle. Better safe than sorry -- discard rather than put inside my car. Lesson learned: store may fill order using the oldest unsold product first or just bad luck.
