changing your car's engine oil and filter is one of the most important things you can do in order to keep your car in good condition
Before draining out the old oil, open the hood of the car and open the oil filler cap on the top of the engine. This will help the oil drain easier because air can flow into the engine
Locate the drain plug on the bottom of the oil pan.
It is normally towards the back of the engine at the car
Loosen the plug counter-clockwise using
the proper sized socket
Locate the filter assembly. Filters are not put in a standard position, and they can be on the front, back or side of engines.so this could be hard,to make it easy Look at the filter you purchased to replace the old one and look for something similar. remove it from the engine. If you can't get it off by hand, use an oil filter wrench. Keep trying. It will eventually come off. There will be oil in the filter, so be careful not to spill it and have a pan underneath to catch the drips.
Lubricate the gasket on the new filter with new oil.
When installing the new filter, remove all packaging, then dip the tip of your finger in the new oil and smear it on the gasket ring of the new filter.
Replace the drain plug on the oil pan. Don't forget to install a replacement gasket or washer. Start threading it with your fingers so as not to cross the threads
Carefully screw on the new, lubricated filter, being careful to not cross the threads. With the paper cartridge filters, they will always come with at least one o-ring, sometimes as many as four different ones. Make sure to replace all of them to ensure that they will not leak.
Add new oil to the car at the fill hole. The amount you need is in the owner's manual, usually listed under "capacities".
Replace the fill cap, check around for tools and close the hood.
