2009 Dodge Challenger R/T: Mum's The Word For Premium Fuel

June 11, 2009


The 5.7-liter V8 for the 2009 Dodge Challenger R/T is a little different depending on whether the car is equipped with thefive-speed automatic transmission or six-speed manual. With the automatic, the V8 is rated for 372 horsepower and 400 pound-feet of torque on regular-octane fuel. It also comes with cylinder deactivation technology fora slight fuel efficiency bump.With the manual transmission (such as our car), Chrysler drops cylinder deactivation and retunes the V8 to take advantage of premium fuel (91 octane or higher). That raises output to 376 hp and 410 lb-ft of torque.

The owner's manual details the fuel requirements. But the chromed fuel-filler door, with its fueling-up-for dummies script, actually doesn't have any premium fuel requirement information on it anywhere. Do you smell the irony along with the gas fumes?

If you're the sole owner of a six-speed Challenger and read your car's owner's manual, it'd be no big deal. But I wouldn't be surprised if our Challenger has gotten a tank or two or regular since we've had itgiven the lack of fuel info and how our staff is in and out of different cars so frequently.

I've addressed the situation (in a very tasteless way) by writing the 91 octane requirement on some masking tape with a Sharpie pen and applying it to the backside of the filler door.
