Curious to see how many different answers we see on here.
It is dispersant which is responsible for suspension of soots in diesel as well as gasoline engine oils. They are not a pure chemical; complex cemical molecule synthesized out of polybutenes. Viscosity Improvers are not responsible for this action; however VIs can ge grafted with dispersants, are called dispersant viscosity improvers. Again dispersant in the VIs are responsible for soot suspension
