I noticed an ad for Techron recently in which they claimed Techron would help a sticking fuel gauge. I have a fuel gauge in an 01 F150 which is very slow to register when you add gas to it. Has anyone had any experience with this, and do you know anything about Techron's ability to help this problem. Also, would Regane or FP60 be able to accomplish the same thing, or is this ability limited to Techron? Thanks
