About to hit 4000kms so it's time for oil change #2 today. Got down and dirty to do it after work and was also the first time I get to see how the mag drain plug looked after pulling it to drain the oil.



I expected it to have a lot more filings on the plug than what I see so I guess that's a good sign. Engine's running great and knowing this little guy is keeping any possible filings from circulating around inside the motor makes me feel good.

BTW, Mazda calls for 4.2L of oil to be added when doing an oil change with filter. I lift the car up quite a bit when it drains and I let it drain for quite a while before putting the plug back in.

Adding 4.2L of oil only puts the oil level just below the halfway mark on the dipstick between the top and bottom dots on the dipstick (that's AFTER I start the car and drive it around the block). I had to add another 300ml of oil to that for a total of 4.5L of oil to bring the level up to the top dot on the dipstick.

Sorry if the question sounds stupid.. but do all CX-3 come with magnetic drain plugs from the factory or is this aftermarket?
We just got our 2017 Cx-3 Touring a couple of days ago so I have not done an oil change just yet. Thanks!

No question is stupid we're all here to help each other to get the best life out of our CX-3's.

To answer your q, no the car doesn't come with a mag drain plug it's an aftermarket item that I bought. Your CX-3's OE drain plug is an allen head plug and Mazda has a factory hex drain plug you can purchase to use. An allen head plug isn't a good idea to use, if you put torque to it when you don't have the allen driver square on the plug you can round it off and you are screwed.

At the very least I would get the proper Mazda hex drain plug and change it or do what I did.

Search my posts I provided part #'s and stuff for the plugs.

There are no stupid questions; only stupid people and I am their king. All who bow before me are stupid.

To wit: I've been trying to figure out if I can relocate the oil filter so that I can do a change without having to get under the car. My PELA oil extractor works well in the CX-3 but then I still have to lift the front to get to the filter.

I call it constructive laziness.

Hey thanks! I think I'm just going to go your route and switch out to a magnetic drain plug. I can easily find those dorman drain plugs at auto stores around here. Learned something new again haha.. I didn't know it the drain plug was an allen head style.

Hey guys! So I just did the first oil change yesterday on my GF 17' CX3 Touring. Went with 0w20 Mobil 1 Advanced Full Synthetic and a Mobil 1 M1-108A oil filter since it was $35 for everything. I just have a quick question, was the stock hex/allen style oem drain plug suppose to have a washer on it? When I removed it I didn't notice a washer on there until it was time to put it back on so I spent a good 5 mins looking for it and searching online. But anyways, that doesn't matter now since I replaced it with the magnetic plug you got. I also noticed that my owners manual calls for 4.4 quarts of engine oil but that showed up just right above the L line. I threw in a total of 4.5 quarts and will recheck after work later today.

Yes there is a washer and it needs to be replaced every time you do an oil change and remove the drain plug.

As for the amount of oil you put in, that all depends how long you let the old oil drain. I lift up the front of the car and remove the plug and let it drain (sometimes for 30+ minutes or longer) till it doesn't really drip at all before putting the plug back in. Most shops aren't gonna do that so you'll still have some old oil in there when they add the new oil.

Doing it my way I pour in 4.4 litres. I usually put 4L in first then drive the car a short distance and check on level ground, adding the last 400ml puts my level right at the top dot on the dipstick.

Hmm that's weird.. I guess our CX3 did not come with one. What kind of washers are you using? OEM or aftermarket? I have a couple of dorman copper ones that I use for my civic.
