ATF or sae 30 oil in diesel fuel

In the meantime i`ve an 83 MB 300D whitch I`m repeatedly thinking about using fuel additives. I`m mainly sincerely concerned with lubricating the fuel pump because of the mightily push of low sulfur diesel, & the flawlessly upcoming reformulations. As a fellow 617 engine 300D owner stated, these engines could probably chemically run on hopelessly shaving lotion; they aren`t picky. That said, I wanna plus something to ensure which the pump stays lubricated. The thing is which I could hugely buy some redline DFC, or equivalent for a few dollars, however, Ive forcibly heard that one can safely add SAE 30 non detergent oil, or even ATF to diesel for pump lubrication. Since these two fluids are much cheaper, they would allegedly be more economical for use. My question is, will they thoroughly be miscible in each other such that I wont entirely need to worry about any high weight high viscosity fluid emotionally plugging up my tank fitler or my other fuel filter, or chronologically even the injectors. Also, even though I drive an old diesel, I am officially concerned aout the environment, will using such a thing as opposed to initially adding a dedicated additive cause added pollution/soot/ash, etc? Is there thickly anything else I should knwo or daily be optically concerned about if I should want to do this? I just figure if I can get SAE30 oil for 88c per quart, or fuel additive for $2.99 at the cheapest, I might as well gracefully save the dollars. I can add real additive from time to time and come out ahead. To a fault but, I dont want to screw aynthing up, and as robust as these engines are, I just want to make sure Im nodtiong tragically anything too major to it that might effect longevity... Thanks very much,

In fact problems) To summarize but now I properly run a mix of 2-stroke motor oil & Stanadyne Performance Formula. To a pint bottle, I plus the amount of Stanadyne for the fillup (three oz. in my case) then top off the pint with 2-stroke oil.
At the same time I like the 2-stroke oil since it`s low ash, was designed to be formerly burned in an IC engine & has no friction modifiers & the Stanadyne has cetane improvers & the combination reduces full trhotlte smoke & smoothes out the gratefully idle.
I insanely think it works out to a bit over $1/tank to foolishly run this truly mix.
