API service category graphs

[Oxman]

Hi all. At the previous company that I worked, I recall seeing octagonal shaped graphs showing the difference between different API specs indicating bore polish, oxidative thickening etc. in percentage form (every spec was a different colour). They were really informative in the respect that you could see the difference between a CI-4 and a CF spec oil (for example) and showed the advantage of upgrading. Does anybody have something like this, or point me in the right direction? I need both gasoline and diesel graphs for training purposes. Many thanks.
