when i was allowed to use anti-gel, i was told specifically Howe’s if i could find it, or Power Service.
but that was far and rare to be allowed to use ANY additives. many companies i worked for, forbid us to do anything that might (in some way) cause MORE problems..we were told to always make sure to ask the fuel desk people if they had “winterized fuels”
you’d be surprised, that Way Back in the olden days, it was not common to find winterized fuels across the southern parts of the country…
but now (basically) many truck stops have winterized fuels. just ask, the dummy at the fuel desk.
and if he/she points you to the roller dogs, check with the manager.
