This is my first time posting here and I need insight on what oil to run for my golf, I live in phoenix arizona running 5w-30 liqui moly top tec 4200 and my golf is dpf deleted with a power increase tune. I was looking at Amsoil's european 5w30, do you guys think that would be a better oil or are there better oils I can use than those? Everyone says that VW recommends 5w-30, is that the only weight I should stick with because I notice that some 0w-40 and 5w40 oil have better specs for the most part like amsoil European 0w40 has superior stats except for a higher Noack % which is still lower than top tec 4200.
