Overview
Changing oil is a very straight forward procedure.
Instructions
- Run the car for 5 minutes to warm up the oil
- Jack up the car, install jack stands
- Get drain pan and position it under the drain bolt located on passenger side of the oil pan
- Slowly unscrew the drain bolt and let the oil drain into the pan
- Unscrew the oil filter housing (this will relieve the system pressure allowing oil to flow out at a greater force)
- Remove the filter and gasket from the oil filter cover (round rubber strip)
- After 5-10 minutes as oil starts to drip, jack down the car and jack up the rear of the car to get all of the oil out
- Go back and jack the front up, secure with jack stands
- Use new washer for oil pan bolt and tighten it. You may lower the car now.
- Open engine oil cover and pour 8 US QT of oil of your choice, close the oil cover.
- Install new filter (coat it in oil) and replace rubber gasket in the cover and just put it on top then tighten the cover
- Start the car and let it warm up, inspect oil pan/filter housing for leaks before driving

Synthetic .vs Conventional
There is a lot of debate on this subject. If your engine is old and worn try running a thicker synthetic oil before trying conventional. If your engine is healthy using proper Synthetic oil will always provide a superior lubrication and friction protection.
Sludge
If you observed engine sludge, prior to oil change open engine oil cap and pour 1/4 of standard SeaFoam can then run the engine for 5 minutes at idle followed by slight 1-3K RPM revs. Shut the car off and continue with your oil change.
