Hey 8th gen community. Didnt know where to post this. I have been giving thought to different oil choices. I have been very happy with amsoil synthetics for a good year now. Before that was Mobil 1 all the way. And once with Royal purple wasnt happy with that. My question is what are you guys using and what do you feel is best with the Si's 2.0 engine. I just bought more Amsoil cause it dont burn off like others gives me good protection and hasnt let me down yet. But I was also considering Motul & Torco. Do you guys think there is a benefit with using anything like Torco or Motul fluids. When it comes to engine protection I want the best stuff. On a side note, does anyone use fuel injector cleaners like amsoils PI or Lucas injector cleaner? Is there any ill side effects using this stuff on a car with not even 40k miles. I like to hear others insight on this thanks.
