Reflo 68 from Petro Canada try to stay away from the synthetic oil types and blends! I think at one time the Clavus 68 was a single still oil but then the manufacturers got greedy and decided that they would blend to get similar characteristics however in Ammonia plants especially low temp -32 or below the oils had a tendancy to separate back into their individual components and any additives would then drop out in the sump.
