Froze up a fuel pump on my Cummins in my Country Coach. Of course Cummins related it to just normal mechanical failure. I had three fuel related failures on the Cummins AFTER low sulphur fuel was released. I now use a fuel additive on every fill up. Does it do any good? If you ask Detroit Diesel, NO. If you ask the additive folks, YES. Bottom line is I feel better, so I do it.
