You are correct that SVO CAN cause polymerization. But it is an EXTREMELY slow process. Slowing the process of polymerization to a "negligible" rate by cutting with diesel is exactly what is wanted. This is the report I was referring to:
Polymerization Report.
As to cutting with RUG vs. D2: either will work, BUT: D2 naturally mixes much better into the VO just putting it into the tank (this can be shown by taking samples from your tank). RUG you will need to THOROUGHLY premix before adding to the tank. This alone makes D2 a more desirable mixer than RUG.
