I'm 69 and first captained a diesel boat in the early 60s. I've never had a fuel problem. If you use high volumes of fuel, then the included additives in newly refined fuel will keep your tanks clean. But if your tanks sit, they will acquire water and organisms. Full tanks collect less unwanted water and organisms than near empty tanks. Cold climates collect less, but still collect. I use an additive every time I fuel.
I have a diesel PU that has a known injector problem with sludge buildups that cause misfiring. In solving the problem I came across Archoil 6200, a fuel modification complex. I also use AR9100 - a friction modifier. Now my injectors are beyond typical working life and operating fine. In addition, I get increased mileage, clean tanks, etc. I now use it in the boat and see better mileage, better winter starts, clean tanks, etc. If interested - archoil.com
Available on Amazon, Ebay and better fuel dealers.
Snake oil.
Keep your tanks clean and buy fuel from reputable (and busy) stations and no additives will be needed. Period.
