Modern Oils are better for modern GDI and turbo engines, but definitely not for flat tappet engines. There are good oils for our flat tappet engines, but chemistry changes all the time. Diesel oils are no longer good due to chemistry changes for modern Diesel engines emission requirements.
I had a Thread about the science behind oils today, but for some reason one of the Moderators decided to close it and merge parts of it into another oil thread with no explanation.
