Gerry, You would probably do far better to contact one of the oil additive manufacturers, tell them what you wanted to do, supply them with a samples/s of your base vegetable oil, and ask them for the information and the appropriate additive package to make a specific engine oil. Throwing in an "oil treatment" such as STP, Wynns, or whatever, would certainly give you a superior oil to one without any additives but it certainly wouldnt be that much superior. As Ed has just said hiring a tribology specialist would be a vast improvement. The problem then is knowing when to stop. Over the years there are not that many of these additive manufacturers like Super Slick 50, Motor Up, etc who have not been pulled over the coals for false advertising because under properly conducted tests by various governing bodies their claims do not stack up. You are generally better to go to one of the specialist oil additive manufacturers and get them to formulate the necessary additive package which is specifically designed for the base oil and to do a particular job than just throw in a can of oil treatment where sometimes some of the additive ingredients may not be too compatible with the base stock you are adding it too. At last count there were something like 49 major specialist companies in this field. B.r., David
