Yes, Delrin (Acetal / POM) spacers would be a good choice - probably better than PVC. Other common materials: Good: Nylon, UHMW PE, Ultem, PEEK, PES (last 3 are expensive) OK: Polyproplyene, HDPE (both materials will easily handle the oil but strength is an issue) No Good: Polycarbonate (Lexan), ABS, any Styrenic
