From the first car I owned, until just recently, I have always changed the engine oil. My father taught me how. He was a truck mechanic in the U.S. Army and then, as a civilian, he worked in plant maintenance. I would say that my father passed on the ‘mechanic gene’ to my older brother and me.
When it comes to changing the oil in one’s car, the first thing needed is to consult the owner’s manual to find the type of filter and how many quarts of oil are needed. Other items are a good drain pan, and funnel. These can be purchased at the auto parts store. It’s a good idea to have a basic set of tools. An extra tool that makes oil changes easier, in my opinion, is an oil filter wrench (specialty tool). I use a socket and ratchet set when I change oil. I’ve also known people who would use an adjustable wrench. I don’t consider this a good idea because you can slip off of the drain plug and damage the flats.
At the auto parts store, you can look up the type of filter required for your car. I would recommend buying the oil in a five quart container so you can pour your used oil into it after the new oil is poured into your car’s engine.
Once you’ve got your supplies and tools, it’s time to get under the car. You might not fit and you’ll have to jack the car up. One other good investment would be ramps. I always save a big piece of cardboard to lay on when I’m under a car. I have a creeper too, but it sets to high for some cars I’ve worked on. Start your car and let the engine idle for about 5 minutes. That way the oil is warm and will drain much easier.
Crawl under your car and make sure the drain plug, you’ll be removing, is on the engine pan. Some new cars have a transmission drain plug. Have your tools with you when you get under the car, and select the proper socket to use. It may be metric or standard. Make sure to have your drain pan close by when you remove the plug. When the oil from the plug hole is down to a few drips, re-install the plug. Locate the engine oil filter. If you’re not sure what it looks like, take the new one out of the box. Some filters are easy to get to, to change, others are not. Use an oil filter wrench, if you have one, and turn the filter counter-clockwise to remove it. Make sure the drain pan is under the filter, if possible, to catch the oil spilling out. Next wipe some oil on the seal of the oil filter and install it, turning it clockwise until it’s tight, then turn it 3/4 of a turn more, this insures it won’t leak.
The next step is to put oil in the engine. Most engines take 5 quarts with a filter change, but consult your owner’s manual. Also, double-check you are pouring the oil into the engine and not some other service port. I know it sounds crazy but it does happen.
Once you have serviced the engine with oil start it up and check for oil leaks by getting under the car, the drain plug and filter should not be leaking. No leaks and oil pressure in the green? Congratulations on a job well done.
