The key findings are on pages 2 & 3. That's enough for me right now. I may read the rest of the report later.
Edit: Read the rest of the report. Interesting stuff.

This study is incomplete. It needs to tell us what the CPG of each fuel is. Crickets Per Gallon. Crap gas has high CPG, top tier tends to be better.
My wife uses Wawa 87 in her Camaro, and I've been trying to get her out of that habit for a while. It's shit gas and a false economy- it's a GDI engine but that doesn't really mean much to her. I used Wawa 92 gas once and I got crickets. I'm hoping this study convinces her because we want that engine to last a while. |

Is there just a simple list of TOP vs non-TOP tier providers?

Well I'll be dammed. Looks like legit evidence top tier means something.
I wonder why there's a significant increase in cylinder head deposits with top tier fuel... the benefits on intake valves does seem to be worth the effort, but it's not an across the board improvement. Last edited by strat61caster; 07-10-2016 at 12:07 PM. |

Interesting that while using top tier gas resulted in much lower valve deposits tht with non-top tier, the cylinder head deposits were actually a bit larger.
It would be also interesting if they measured injector deposits in a GDI engine. |

P.S. why this is posted in the FRS section, not in General automotive?

I see that Sunoco, Tenneco and Gulf are not Top Tier.
