The 2009 Dodge Challenger is a high performance car and proper maintenance will ensure that the car's powerful engine runs at optimum performance for a long time. Changing the oil according to the manufacturer's specifications is part of a regimen that will keep the engine properly lubricated, and this is a job you can do yourself. The Challenger's base 5.7 liter Hemi engine uses seven quarts of 5W40 synthetic oil, while trims with the 6.1 liter Hemi engine take 10W40 synthetic oil.
Park the car on a flat and level surface. Open the hood for access to the engine compartment. Locate the oil cap on the top of the engine and twist it counterclockwise to remove it. Place it to the side.
Locate the splash shield directly under the car. Unbolt the four bolts on each corner with a socket wrench. Place the splash shield to the side.
Place a drain pan underneath the engine. Unscrew the drain plug from the bottom of the car's oil pan.
Allow all the oil to drain. Screw the drain plug back in with the socket wrench.
Unscrew the oil filter with a filter wrench. The filter is in front of the engine. Place the old filter with the waste engine oil. Pour fresh engine oil in to the filter and spread some oil on the gasket at the top of the filter. Screw the new filter on by hand.
Bolt the splash shield back on under the engine. Tighten the four bolts with a socket wrench.
Pour six quarts of oil in to the engine. The oil needs to be poured where the cap was removed.
Pull the engine oil dipstick located next to the engine and wipe it with a fresh rag. Insert the dipstick back in to the dipstick tube and pull it back out. Verify the level of the oil by where it stops on the dipstick. If it is below the full line, fill at half quart intervals. Repeat this step until the oil is on the full mark. Screw on the oil cap.
Start the car and allow it to idle. Let it run for five minutes. Turn the car off and check the oil again. If it is low, fill until the dipstick reads full.
