1993-1996 Cadillac Fleetwood Oil Change

Place a jack underneath the frame near the passenger side front wheel.

Raise the car with the jack until you can work comfortably under the car.

Place a jack stand on the frame immediately behind the jack.

Slowly lower the jack until the car is resting on the jack stand and remove the jack.

Locate the oil drain plug along the side of the oil pan. It is a 14 mm hex bolt that faces towards the driver side of the car.

Place an oil drain pan under the oil drain plug to catch the old oil.

Use a 14 mm box end wrench to loosen the drain plug until you can turn it by hand.

Continue to loosen the drain plug by hand until it comes free and oil begins to drain.

While the oil is draining, wipe off the drain plug with a clean rag or towel.

Remove the old drain plug gasket and replace it with a new one. Be sure that the new gasket fits over the threads of the drain plug.

Wipe off the area on the oil pan around the drain plug with a clean rag or towel.

Reinstall the drain plug and tighten it by hand first.

Use a box end wrench to tighten the drain plug until it is snug, but do not over-tighten it.

The oil filter is located right next to the oil pan underneath the car.

Loosen the oil filter by turning it counter-clockwise with your hand or an oil filter wrench.

Once the filter comes off, place it with the open end facing down in the oil drain pan to allow the oil to drain out of it.

Dip a clean, gloved finger into a new bottle of oil and spread a thin layer of oil onto the gasket of the new oil filter.

Fill the filter up about half way with new oil.

Wipe off the oil filter threads and contact area on the engine with a clean rag or towel.

Place the new oil filter over the threads and turn it clockwise until it is snug.

Place the jack on the frame and raise the car until it is no longer resting on the jack stand.

Slowly remove the jack stand and lower the car to the ground.

Locate the hood release lever near the driver side footwell and pull it until you hear the hood click open.

Lift the hood release latch near the center of the front grill and raise the hood.

Locate the oil filler cap on the passenger side valve cover.

Remove the oil filler cap by turning it counter-clockwise and lifting it off of the valve cover.

Place a funnel into the oil filler hole.

Pour 5 quarts of 5W-30 or 10W-30 oil into the funnel.

Reinstall the oil filler cap and tighten it by turning it clockwise until it is snug.

Remove the dipstick from your engine.

Wipe it down with a towel or rag to remove all the oil and ensure an accurate reading.

Reinsert the dipstick, then remove it. Oil should now cover the end of the dipstick up to the top hole.

Lower the hood, then firmly press down on it until you hear it click back into place.

Allow 12-24 hours for all of the oil to drain out of the old oil filter.

Take your old oil and filter to a recycling facility. Most auto parts stores and repair shops accept these at no charge to you. In addition, some cities and/or counties have a service where they will collect used oil and filters from your home.
