Abstract This invention relates to reformer distillates as gassing additives for transformer oils. The reformer distillates have a 1-ring and 2-ring aromatics content of at least 98%, and are added such that the transformer oil contains less than 10 wt % of reformer distillate. The invention also relates to a method for preparing transformer oils containing reformer distillates and having excellent gassing tendency, oxidative stability, viscosity and volatility.
