Oil capacity for Mazdaspeed3?

They can void your warranty for dirty wheels, if you believe stuff you read here. My spin-on platform was a Mazda part. From what I've read here, the cars they sell in Europe have spin-on filters.

Then if they sell it I would think M-M could cover you.


I may get one, that setup to change oil is as retarded as any I have ever seen

Um, yeah, lots of them are, in fact, most I've seen inside various engines I've worked are a plain tube, straight into the pan. A good effort at trying to get out of admitting you're wrong, though. (wink)

dipsticks aren't hollow. there are flat metal ones, plastic ones, braided metal ones, and even some cars that don't have any (******* mercedes)

Some of 'em get pretty close. I've met more than one hollow dipstick. Met a few shallow ones, as well. Never seen one on a motor, though.

i'd like to know where you found a hollow one, cuz i've worked cars before

No, but the tube that the dipstick is inserted into IS hollow.
Since you still couldn't figure it out:

The dipstick tube is analogous to the straw.
The end of the dipstick is analogous to the finger on the end of the straw.
Notice the o-ring (which forms an air seal) near the end of the dipstick.

ohhhh the tube that the dipstick goes into. well now that makes sense because that is hollow.

If there wasn't an o-ring (air seal) near the end of the dipstick, this "oil level discrepancy" wouldn't happen.

All you have to do is lift the dipstick up a couple of inches, which allows some air to escape (and the oil level to rise in the tube).

The dipstick does not reach into the oil pan.


Ain't physics cool?

so that little o-ring seal on the dipstick handle makes the entire engine block air tight? so then what is the pcv for?

and dipsticks do reach the oil pan (except maybe the dry sump systems, not sure how you measure the oil in those) but the regular types have oil going all over the place from the crankshaft slapping it around (in addition to the pump putting oil through all the other systems).

that's why the oil level is so important. there needs to be enough so that the crank can pick some up and throw it around the inside of the block, but not so high that it creates more drag on the crank and a whole bunch of other stuff.



sorry for the long and belated reply. and sorry to sound like an asshole, but if i come off as one oh well

5.5 qts. every time, spot on for me...

No, of course not. Why would you even consider it?

They often do, but not in this case.
It's obviously not possible since the dipstick tube is longer than the dipstick
