Always been a M1 fan, but had some PUP so I put that in it last month. It's sn plus on the bottle do I'm sure it's fine for TGDI and it's got A approval but not the B. I would assume it meets B spec just not certified, but it cost a little more and is hard to find sometimes so why bother. Anyways I've usually used m1 in my vehicles, but heard a lot of talk on the magnatec on the ecoboosts. Is it better than M1 in this application and if so, why? Thank you.
