You would look at VOAs of both oils and see how they stack up. I wouldn’t use the $25 analysis to determine that, though.What do you look at on the VOA or used oil analysis to tell if it worked as advertised? For example, let's say I want to know how well it meets the requirements of Volkswagen 504 00 approval, as advertised that it does. What parameters of the used oil analysis/VOA would I look at?
More to the point, a $30 used oil analysis/VOA is all that's needed to establish compliance with a manufacturer approval?
