I have a 92 Gq waggon Td42 turbo, I done a search and nothing came up the two most commented on oils are the Delo400 and the Shell Rimular X are they still the best or is there something else on the horzion , I like what I have read about the Delo400 but $103 for ten ltrs is a bit much for me so I was considering the Rimular X, I have been using Valvoline Nexgen but the engine seems a bit noisy especially the tappets and that is about $ 135 for 20 ltrs
