I always thought that the Olizum brand of motor oil shut down in the 1970's. At the Hershey car show I was in conversation with someone at a location that sold old signs and on of them was Oilzum. The person said that you still may buy Olizum from a company known as Dennison Lubricants located in Mass. Does anyone know if this is the REAL oilzum or just another oil wearing the Olizum name? I remember the caster based version that many midget racers used during the 60's and 70's.
