How to change your oil

The first thing that I recommend is that you read the owner’s manual that comes with your car. It will show you where all the key things are that you will need to know. For instance, you’ll need to know the location of the dip stick to check the oil level, the location of the oil filler cap to add more oil, the location of the oil filter, and the location of the oil drain plug.

You will need to be under the car to be able to access the oil
drain plug. With some cardboard on the ground (to catch any
drips), place an oil catch pan under the oil pan. Now, loosen
up the oil drain screw. Remember the "righty tighty, lefty
loosey" rule. Turn right to make tight and turn left to make
loose.

Slowly unscrew the drain screw. Before the screw is all the
way out, you will notice some oil starting to come out. At
this point, you can do one of two things: leave it like this
(it will drain but will take more time) or carefully grab the
screw with your fingers and manually turn in out the rest of
the way. Please be aware that the oil behind it will want to
push the drain screw out once it is free of the threads. Then,
the oil will drain out very fast. This could get messy if your
forearm gets in the way.

Now, while the oil is draining, you can remove the oil filter.
On most cars, it is a spin on type of filter. You will need a
tool specially designed for this job. There are several
different types. There are some that are strap wrenches, some
that look like big socket wrenches, and some are a specialty
plier type. Any of these tools should be available at the
store where you purchase the oil and filter. Ask the associate
at the store for a recommendation. Personally, I recommend the
socket type. However, there are many different size filters,
so one socket will not work on all filters.

Now, one thing to remember when removing the old filter is
that it probably still has some old oil left in it. Therefore,
some caution should be observed while removing the filter.
Once the old filter is out, look at the location where the
filter came from. You should see a large tube with threads on
the outside. The filter threads to this.

Then, if you look closer to the engine, you should see a
smooth surface all the way around where the filter touches the
engine. Make sure that all of the old filter gasket was
removed with the old filter. If any is left, the new filter
will leak.

Once you are sure the area is clean and ready for the new
filter, take some fresh oil and pour some into the filter.
Then, take some fresh oil and smear it on the gasket. This
will help the gasket and prevent it from tearing as you
tighten the filter. Don’t over-tighten the filter. Follow the
instructions on your owners’ manual. Just for reference, pre-
filling the oil filter helps avoid dry starts from an empty
filter.

Once you have the oil filter in place, go back to the drain
pan. By now, it should be completely empty. Wipe the area with
a dry cloth and then screw in the drain plug. Use a wrench to
snug it tight. Don’t force it. Once the drain plug is
installed, you can pour the new oil in to the engine. Make
sure you read the owner’s manual to find out the correct
amount and type of oil.

Before you start your car and drive away, make sure you check
the dipstick to double-check the oil level and take your oil
pan out from under the car! Also, after you’ve run it for a
few minutes, stop the engine and peek under it to look for any
oil leaks that might have developed. If you find any, you’ll
need to either tighten the oil drain plug or oil filter.
