ATF in the fuel for clean injectors?
I have a friend who used to be a long-haul trucker and he was telling me that once a year he would add ˝ quart of ATF per 100 gallons of diesel fuel to keep the injectors clean. I asked whether he ever used Marvel Mystery Oil and he said that too would work, but ATF was cheaper.
Has anyone had any experience using either with the fuel to keep the Cummins injectors clean? Many of my airplane friends use it both in their fuel and oil and swear by it as a cure-all for nearly everything. However, I won’t admit to using it here on the Forum, big brother, the FAA, might be listening in.
