How To: Oil Change

Postby ten2doyle102 » Mon May 18, 2009 3:42 am

I made a quick little how to for doing an oil change. I took lots of pics for everyone to see. This is really ment for someone that really never worked on a car, but would like to! :) So, here we go! :) I would say that on a lever of 1-5, its definitely a 1, anyone should be able to do this. I like to do this with the car still hot. The oil flows better and cleans out more. Its up to you though cause I know that its not fun...


To start, Here Is everything that you'll need.

-17 mm Wrench
-Oil
-Oil filter
-Oil pan
-Funnel


Image


Ok, Heres the top of the motor

Image

You'll notice the Oil Fill cap towards the front of the motor, the little black round cap

Now at the bottom of the motor, you'll find the oil drain plug. On a standard e30, the plug is on the front left side of hte motor if you where looking at it toward the car. My car is different since its an IX and the plug is on the back right of the motor. On a 318 (m42), the plug is right on the front of the oil pan.

Here's Mine

Image

Unscrew the plug and away it goes!

Image

Once the oil is done draining, replace the plug and tighten it up


Next, is the oil filter. On an m20, the oil filter is in a location of which I feel is really stupid. As I said before, I like to the oil when still warm, but I let the car cool for a while because of this....

Image

Image

On an m42 (318), the filter is a cansiter style. Its a aluminum tube that is located on the drivers side of the car. Its got a 13mm hex bolt and the top will come off to remove the filter.

Once the motor cools, unscrew the filter BUT make sure the oil pan is underneath the filter area. Oil WILL come out when you remove it.

Image

With the filter off, take the new filter and lightly coat the threads and the seal with oil.

Image

Screw on the new filter, but don't overtighten it. I usually turn it till it requires you really grab it, then I turn it 3/4 - 1 or so more turns after that.



Next

Open the oil fill cap. You will need 4.6 quarts of oil of an m20 and 5 quarts of oil for the m42. Well, fill her up! Check the dip stick to verify the level.

Image


Replace the cap, start it up and let it run for a sec and then turn it off. Recheck the oil level and if needed, add more.


And Your DONE! Congrats on your first oil change! :) :) :)

I have tried to do it in the past right away....but I just give up now and wait about 45 min for it to cool. I just got sick of going to work with tons of little red burn spots on my hands and forearms.... :)

Awesome write up! Great pictures too. Just curious but what oil do you guys run? I hear syntheic is not so good with these older motors,.... to be honest I'm yet due for an oil change. :)

Well, you can see what I run. Really, its a personal choice. Alot have said the synthetic will just burn off right away, but when I was running that, it seemed ok. I have been running Castrol GTX 20w-50 for the last two oil changes and have noticed a lot less oil loss and the motor is slightly less noisy. I go with the 20w-50 also because I have read that our motors were designed to run on the thicker stuff due to the set up of the valvetrain.

Also, something that is also brought up alot is the amount of zddp in the oil. Its a lube that is added to the oil that helps with the wear and tear on the valvetrain in our cars. I guess over time, companies have been fading the zddp outta their oils for enviromental reason which is part of the reason why auto manufactures switched to roller cam folllowers and such in newer motors since there is less friction. That being said, for our cars, we need oils with higher levels of zddp in them. I am not sure which oils or how you even find out how much is in them, so maybe some one can elaborate on that.

I hope that made a little sense! :)

My guess to find out if it has ZDDP would be to check out the MDS (material data sheet.)

Castrol GTX 20w-50 -MDS can be found at the oil companies website. part 8 I think has what's in it.

ZDDP/ZnDTP/ZDP. = zinc dialkyldithiophosphate aka zinc?

How come your car has two cables on the throttle body?

Because it is twice as awesome! :)



No really, its because one is for the gas pedal, and the other one for the crusie control. Tony posted in your reassemble thread about that. The slot you originally put it in was for the cruise control and is why it was revving to the moon.
