So you basically came here to reaffirm your own decision of running Mobil anyway? If cost wasn't a concern than just by Amsoil and run that or HPL?Thanks for the reply. I’m not interested in running a viscosity that’s not called for, or a premium fuel. I’m interested in whether I should use Amsoil over the existing Mobil 1. Cost is not a concern since over the course of a year of oil changes it doesn’t add up to much.
It has been well documented that turbo DI engines are better on a higher octane even if the maker states 87 is ok. Do some research of LSPI and you'll see why.
