Several well know lubrication specialists claim they can replace additives, but had very poor results. In talking to lubrication engineers at Lubrizol, the designers of additives, I found they do not recommend adding new additives. In order to work properly they should be blended at the refinery.

My company supplies the electrostatic purifiers that GE recommends for its turbines. It works by removing submicron particles, which act as a catalyst that increase varnish and deplete additives using Balanced Charge Agglomeration. We have these machines on more than 800 gas and steam turbines in most countries in the world. They work very well at keeping oil super clean, removing varnish and protecting additives. At seven 7FA plants in the southeast of the US, they are on their 8th year on their oil. The oil looks like Pilsner beer. The varnish potential is near new oil and the additives are over 80% of remaining useful life. Arecent tear down showed mo varnish in the lubrication system.
