Fluid Capacity on the B6ZE crank case/sump.

Really interesting post on instagram here:

In case you've also ever wondered how much oil is ACTUALLY in your sump with the engine off, here's a 1.6 MX5 sump with the specified 3.2L worth of water in to show the level, followed by overfilling by 0.5L and finally by 1L (shown with 5 fingers and 1 finger respectively). I then also went and measured that level relative to the sump baffle, and finally dropped that baffle onto the built up block and measured to the crank counterweight and my Eagle rod cap, and bolt edge, to see how much oil you could realistically fit in the sump before you start dipping rotating components on cold starts, when all the oil is sat in the sump and not flowing round the engine.

The actual reason for this is that I'm struggling to fit my oil cooler in a nice position without having to invert it (fittings at the bottom). With the cooler inverted, the oil that usually stays trapped in the oil cooler and lines would end up draining back into the sump with the engine off, meaning that the dipstick is no longer correct and the cold fill level needs adjusting.

All that led to me wondering exactly how much extra you could put into a standard sump before you start to dip the crank into the oil on startup, and it looks like the answer is about an extra litre on the B6 engine!

I still don't want to fit the cooler inverted for that reason, as well as poor self-bleeding, and may end up looking at a slightly more compact cooler instead, but once the question popped up, it had to be answered

Another quote from the insta thread, which I'd love to find the link to the source of..

I've always overfill by about .5 to .75 per things read on miataturbo.net. stellar. Also, could be why I'm puffing (little stronger pressure)

Interesting, thanks for posting it

Does the OEM level account for 'sloshing' from side to side under cornering? A static fill is very different to a moving car.

when the engine is running theres oil in the head to consider against the level in the sump

Rich.

This is approximate dip stick readings should anyone care - for the mk1/mk2 1.6 engine dip stick.

'Probably Fine'

That's confidence-inspiring
