Perfect for Winter Cold!

I use to help my car start reliably and run smoothly in the extreme cold. During winter months I make sure to use every 4 fill ups. It helps remove moisture from my gas line as well as clean my fuel injectors. I add a full bottle when my tank is 1/4 full and drive a few miles before filling my tank.

Minor performance issues? This is worth a try.

I tried the Molecure PEA Complete Fuel System Cleaner because my car had started feeling sluggish with a rough idle when cold. I poured the entire bottle into a near-empty tank (about 1/4 full), drove around and ran a few errands, filled up with regular gas, and drove normally. After about 100 miles, the engine smoothed out noticeably, idle improved, throttle response felt sharper, and I gained a couple mpg on mixed driving (28-29mpg to about 31mpg). For the Walmart price, it worked well and I plan to use it every 3,000 miles as maintenance. If your car has minor performance issues, it's worth a try.
