fibonaccio best you stick to what you know about. As a founding member of BITOG that has over 30,000 worldwide members I know a bit about oil. You are using U.S references and you have CAFE which affects oil viscosity, nowhere else has CAFE. Most turbo engines here run 25W70 or 5W50,
0/5W20 doeswn't exist and XW30 is rarer than rocking horse shite.
