Re: Mixing Castrol r30 castor with synthetic oils
No castor oil from the pharmacy shouldn't be used, it contains sugar, and other additives that are not good for the engine. Don't do it. Use Maxima 927 (personal favorite) or Benol or Castrol A747 (spendy!!) or Techniplate from Klotz. These are specifically blended for 2 strokes. Cutting corners can get expensive later on.
