If not upgraded, VGO is blended into residual fuel oil. However, this is fairly rare since the value of VGO is much greater as a feed into upgrading. Often, if a refinery lacks enough cracking to upgrade the VGO it generates, it will sell this as an intermediate to another refinery, rather than downgrading it by blending into residual fuel oil.
VGO is often sub-divided into a lighter and heavier fraction called LVGO and HVGO, respectively.
