Fuel Gauge problems caused by bad gasoline...
Hello fellow Bonnie Owners-
After experiencing a rather strange behavior of my fuel gauge and reading about Shell Oil / Texaco refineries producing high-sulfur gasoline, I want to point out the following information:
The initial report described the situation occuring within the southern US, mainly in Louisiana and Florida. This is NOT the case! I live in the Northeast US and am finding the same issue here. A little research shows that most main petroleum suppliers have refineries located near the Gulf of Mexico with underground distribution networks (steel pipes about 1 to 3 feet in diameter buried underground) that carry the refined petroleum products (gasoline, diesel, heating oil, kerosene, etc) to regional terminal sites for further distribution. Central Pennsylvania is home to a few of these sites and they receive what is known as "wholesale product" from any number of refineries. Most local gas stations get their deliveries from the terminal, sold at "spot prices" and are not branded until they are in the truck. At that point, it becomes the brand (Sunoco, Exxon, BP, Shell, etc).
OK, long discussion with a short result. Be cautious about the fuel being used even if it is not pumped from a Shell or Texaco pump. In a pinch, they can get a delivery from the terminal that may have received product from that particular refinery, and also note that some of that high-sulfurous gasoline may still be in the 1000 mile distrubution line awaiting further delivery.
Hope this sheds some light on this issue.
