I had an issue with the fuel gauge on my 2007 Ford F-150 XLT 4X4 with 94,700 miles. For the past 2-3 months, my fuel gauge would show empty when I filled up and would not read accurately. Recently, the fuel gauge situation seems to have resolved itself. About 2-3 weeks ago, I added Sea Foam High Mileage to my gas tank before I filled up. After going through a tank of gas, the fuel gauge seemed to be working normally. I can’t be sure that the Sea Foam had anything to do with remedying the situation, but it’s working now. Maybe it’s just a coincidence. I’ve been on two trips to the Texas coast and the gauge is working properly. Could it be Sea Foam High Mileage corrected the issue with my fuel gauge/fuel sending unit?
Thanks for writing in, Peter. A stuck fuel gauge is not something that we claim Sea Foam High Mileage or Motor Treatment can fix (at least consistently). However, some people have reported using Sea Foam to fix their stuck fuel gauge problem. Sea Foam does a very good job cleaning fuel gum, varnish, and residues, etc., so if it was stuck because of something like that, it certainly could have (seems like it did!) fix the problem.
Another idea: try adding a full can of High Mileage to a low tank (1/8-1/4 or so) of fuel. The high concentration of High Mileage works very well to clean. It’s a great way to make the most out of a can.
Thanks again for the note!
