I was thinking about buying the weakest oil such as City Star and buying one of those super duper fortified additives and mixing it to proper ratios. Then perform a VOA to see what kind of oil I would get. Obviously nothing is as good as a good oil to begin with. I would not do this to use in my vehicles (or 30 yr old OPE for that matter). I would not use oils that PQIA has shown to have high iron or any other metals such as this. I kind of have a mechanics bet riding on this. A co worker of mine says you can use a cheap oil and fortify it with an additive and make it as good as a quality oil. I disagree.
Any suggestions as far as oils and additives?
