I wonder if you could use ARx in the fuel tank? If so how much on a 25 gallon tank. Truck is a 02 F-150 5.4L. Motor has 40k on it and injectors are aftermarket replacements 21 lb/hr.
I find it a vastly interesting additive being what it does work with. It seemed a possibility. There are so many fuel system cleaners and my short driving cycles I like to keep things clean.
The snoblower and lawnmower hold about a quart each but the weed trimmer holds very little. I have a quart of synthetic for it and it might just be a lifetime supply. I run the same weight I use in my truck 5W20.
