Premium Vs. Reg Gas

[Mrono]

So what do you guys use in your mini's? I use reg because if I use premium it rattles something fierce. My dad put premium on a trip to utah and he complained on rattles the whole time, i heard them when he got back and put reg in and they went away

are you sure the rattles weren't valves ticking. Often times on FI cars you will get early detonation and make a "rattle" sound just from bad gasoline. Cheap 91 octane is not always better than "good" 87 octane.

Me... I would never put anything less than 91 in a FI car. Too bad we don't have 93 here in Phoenix.
