You’ve probably heard the story about BP Refinery Recall back in 2012. During that time, thousands of drivers in parts of Indiana and Illinois faced hefty car repair bills after a national chain sold about 2.1 million gallons of contaminated gasoline that was believed to cause engine problems. According to a release from BP, the fuel contained “a higher than normal level of polymeric residue” which contaminated 50,000 barrels of regular unleaded gasoline from its Whiting, IN, refinery. The fuel was shipped to hundreds of gas stations in northern Indiana under the BP brand, as well as unbranded to many independent stations. According to Chicago local news outlets, scores of drivers began coming to repair shops reporting hard-starting and stalling engines, “check engine” lights, odd noises and other signs of engine trouble. source: knowyourparts.com
Although cases involving contaminated gasoline are not reported as often as before, the problem still exists. Sediment or water contamination of gasoline is still a common problem. One reason is that fuel-quality inspections at your local gas stations are not mandated on a federal level. Many states may test for contaminated gasoline, but if there are state cutbacks, those inspections may be the first to go on the chopping block which lead to inspections occurring less often and for less gas stations over the years.
The gasoline holding tanks underground can get contaminated simply by water runoff , dirt, and other contaminants entering the tank because of fuel caps that are worn out or simply not tightened properly.
Modern filters at the gas pump may catch large sediment particles, but they still allow some smaller particles and water which can lead to your vehicle misfiring, poor gas mileage, and a costly trip to the auto repair shop. The Clean Fuel Screen Filter has a micron filter which stops even the smallest of particles from entering your tank.
