My spare truck has very old gas in it, and this got it running so much better.

Someone recommended this product, so I gave it a try, and I love it. I will continue to use it every 3000-5000 miles. I lasted almost a week on a half tank of gas.

Great product and cheaper than auto parts store. Fast delivery. Works well keeping a 93 Jeep with 150,000 miles going strong.

el precio seguramente esta incorrecto, ya que prometen un paquete de 12 piezas a un precio muy bajo. pero el vendedor no contesta, ni hace el envío, ni nada. hasta podria ser una estrategia de lavado de dinero
