1.Drain the oil
Yourcar engine must be turned off and cool to touch. Most modern car engines run ataround 150'C. Hot oil can cause serious burns.
Find out where your drain plug is (check your car instructionmanual). Place a big enough container directly under the drain plug and thenunscrew the plug in an anti-clockwise direction. If you can't do this by hand,use an oil filter wrench. When all the oil has drained out, screw the plug backin making sure it is firmly in place.
2.Replace the filter
Place a container under the oil filter to catch the oil. You willneed an oil filter wrench to remove the old oil filter. Before you put your newoil filter in, coat it with a thin layer of oil and check the instructions inyour car instruction manual. Most manuals will tell you to give the oil filterone more turn after the gasket has made contact. This is important because youdon't want it too loose as it will leak or so tight that you can't remove it.
3.Add new oil
Consult your car instruction manual to find out how much oil yourcar needs. Pour the new oil into the oil filler cap in the valve cover using afunnel.
Most cars use between 4.5 and 5.5 litres of oil. If you don't know how much oil your car takes put in 4.5 litresto start. Check the oil level and if it's still low, add a bit more. Rememberto replace the oil filler cap before you close the bonnet.
4.Test it
After all your hard work, test it by starting your car engine. Theoil warning light should be off. Look under your car to make sure there are nooil leaks. Next, turn off the engine and let it rest for about a minuteallowing the oil to drain down to the crankcase. Pop the bonnet and check theoil level. Remove the dipstick, wipe it clean, replace it, and pull it outagain. Most dipsticks have a ?full? mark on it.
