Does anyone in the group put 87 octane gas in their Pacifica. If so, how is the performance. Thank you.

What is in the owner's manual?
I doubt anyone here has a dyno to measure a difference. Therefore, all you will get is an emotional or otherwise worthless opinion.

hmmm. 87 octane fuel is the only recommended fuel for this vehicle. The use of a higher octane fuel could cause drivability problems in the long run. Over a period of time High octane (slower burn) fuel could leave deposits on the pistons and cause stalling, hesitation and even pinging problems. Just a thought

The 3.5L 250HP engine requires 89 octane fuel in my manual.
87 is okay but they recommend mid-grade.
You didnt specify year, I looked up 2005 and 2007, it stated 87 octane
>I have an 06 Charger SXT with the same 3.5L and it says to use 89.
That is true, that application specifies 89 octane
