Where do they even sell this oil anymore, I scored 3 cases of it at a auction about 8 years ago, (5w30) it seemed to be excellent oil, I have never seen it in the stores though. I used it in my work car, a 1978 Cadilac Elderado. It ran super smooth on it and didnt use any, where it used oil with other brands. I would have bought more if I could have found it.
