You can look all you want. But you will be fooled like everyone else on the site. Then even after you chose, how will you know it's actually better?
Take, say Valvoline for example. Study the additive package.
Previous Valvoline formulations had a poor reputation because in uoa, even though they performed well they appeared to have a weak add pack. There are additives that are not detected on oil analysis and that's how oil reports can fool folks.
