Yes sir I hear ya on that. I have a monster brew of Formula Shell 5w30, Super S, Quaker State Ultimate Durability, Havoline Pro DS, Pennzoil Platinum, PYB all mixed together in an old 5 qt container. It totals about 2.5 qts. I am going to take it to the recycling center and they will give it to someone else who wants to take it for free. If I had OPE I would gladly put it in that.
