Besides being able to choose a color of oil to go with my decor, it is also clean burning.
This lamp oil surpassed my expectations; I was amazed when I opened the bottle and could not smell any oder coming from the fuel. It is completely transparent, burns cleanly and is truly odorless!
I have been using this oil for over 40 years. I have on occasion tried less expensive oil, but always returned to Wolfard. Reason is it remains clear for my Wolfard lamps.
