Bentley GTs are marketed as a smart and stylish sports car. All the sophistication and style of a Bentley GT comes with a hefty price tag. Though performing your own maintenance procedures on a Bentley GT certainly won't offset the cost of the car itself, every little bit of money saved helps. One such money-saving maintenance procedure is the standard oil change. Changing the oil of your Bentley GT is a simple process requiring basic tools and equipment.
Drive your Bentley GT around with the heater's foot blowers running. When your feet are warm, return to the flat area where you will perform the oil change. Driving until the Bentley's engine is warm will allow the oil to thin out, making it easier to drain the system.
Chock your Bentley's back tires with blocks of wood, jack its front end up with the tire jack and support it with jack stands. GTs do not have much ground clearance, so it is nearly impossible to access the oil plug without lifting the front end and supporting it with jack stands.
Locate your GT's oil tank and the the plug at the bottom of this tank. The tank is identifiable by locating the plug, which is the lowest mechanical component on the bottom of the GT. It is a large nut jutting out of the bottom of a basin.
Position an oil drainage pan directly underneath the oil tank's plug. Most oil pans come equipped with a wide, flat funnel on one side designed to catch oil and prevent splashing. Make sure your oil drainage pan can hold the maximum capacity (about seven quarts).
Loosen the oil plug nut with a socket wrench and unscrew it completely. Oil will start to drain immediately, so work quickly.
Pop the hood and pull out the oil dipstick, located next to the oil cap (which is clearly identifiable by the oil can and oil drop logo on its top). Removing the dipstick allows air to flow into the oil tank, aiding in the speed of the drainage.
Allow the oil to drain completely from the tank of your Bentley GT.
Replace the oil plug by hand. This is not the final replacement, but only a precaution to prevent oil from dripping out of the tank when you reposition the oil drainage pan.
Reposition the oil drainage pan directly underneath the oil filter (located behind the oil tank).
Wrap the strap end of an oil filter or strap wrench around the oil filter and turn the wrench counterclockwise to loosen and remove the filter. Oil will pour out of the connection point and the filter.
Rub some new motor oil around the lip of the new oil filter. This will simultaneously prevent the filter from burning onto its connection point and aid in the future removal of the filter.
Screw the new oil filter in place, turning it one quarter turn past the point when it stops turning smoothly.
Tighten the oil plug with a socket wrench.
Remove the oil cap and place a clean funnel into the hole left by the removal of the cap. The funnel should either be new or the same funnel you used for changing the engine oil of your Bentley GT previously.
Pour slightly less than seven quarts of oil back into your engine's oil tank. Residual oil always sits inside the tank, even after you have drained it until oil stops dripping from the plug hole and filter hole.
Let your Bentley GT sit for five to 10 minutes. This will allow the new engine oil to settle into the tank and filter.
Check oil level in your tank using the dipstick. Add or drain oil until your tank is appropriately filled.
