06 Hemi runs better with mid-grade
ORIGINAL: nos4fuel
i ran regular in my 03 Hemi for 3 months and only got 10.3 mpg since i do very local driving....mostly not over 5 miles on way. It started stalling and running poorly then finally the check engine light came on so i took it to the dealer. All 8 plugs were shot and the ECU had set itself so that it was only making 300hp instead of the full 345, after having it serviced, cleaned, remapped, and tuned-up back to stock, i refused to pay the bill until they drained my gas tank and filled it up with 89...on their tab. They did this, and they were happy to which made my jaw hit the floor. Now, it runs like a champ and i even find myself starting the motor and standing by the exhaust pipe just to hear it rumble....I LOVE THIS TRUCK. If it could cook, i would stay single forever, hahahaha!

Your HEMI has only 8 plugs? Funny, Both my 2004 and 2006 model have 16 plugs. According to this article so did the 2003.
