Excellent thread! Anyone know approximately how much PS fluid it takes to get into the "normal" range if the little dipstick on the cap is just barely getting fluid on it (like, 1 or 2mm)?

These capacities are guidelines, and you should be paying attention to your engine oil dipstick.

Due to the fact that the footprint of the oil pan is so large, the car is subject to oil starvation in high-g cornering and heavy braking. For this reason people who track or autoX their cars often overfill the motor slightly (by 1/2 quart, but no more than 1 quart over full).
My car is a 97MY with a 10/96 build date and 3.2L S52 motor. Yet my manual states the capacity is 6.9 quarts?

Can't go wrong with 6.9. I usually run 7 or more.

"most" guys who do any auto-x/track usually run around 7.3-7.5qts

So no one has anything to say about why my manual says different info than this thread? Could it be the manual says capacity with filter change? I mean i have the 3.2L yet the manual says 6.9 quarts?
And a side note, i was doing a canyon run and i actually experienced the oil starvation tick of the hydraulic lifters, so I'm going to overfill it. So on a 3.2L about 7.3-7.5 quarts is sufficient? I want to do autocross this summer and don't want to starve it. Mobile 1 is on sale for 5 bux a quart right now, so i'll just pick up 5 and do a change this weekend, because i have to replace the oil feed line for vanos anyways (it is leaking).

Not sure what to tell you. My 3.2L manual says 6.3 and the Bentley says 6.3. That being said, who cares? Go by the dipstick. Capacities are only a guideline so you know how much to dump in before you check the dipstick. Always go by what the dipstick says.

Overfill a little if you'd like. But at autoX, the biggest thing you can do to protect your motor is let the car warm up sufficiently before you do a run. I did a lot of experimenting last season with my car and 2 other local members' E36 M3's. The simple conclusion we came to is this:

-Don't let the oil warm up sufficiently before a run...get lifter tick.
-Let the oil warm up sufficiently before a run...don't get lifter tick.

Also, after you do a run, let the car idle for a minute or 2 before you turn it off. If you did partially starve and introduce air into the lifters it will evacuate it. I've noticed if I turn my car off right after a run, it will sometimes tick when I start it back up again (even if it wasn't making any noise before I turned it off).

I've been through a good number of autoX events following those rules, and my car hasn't made any lifter noise since I started abiding by them. I got lifter tick in the past from not paying attention to those things.

I read mine from the back of the manual, in technical data under capacities. I'll just fill it up and keep checking the dipstick.

So, on the dipstick, i know you are supposed to be between the 2 notches. Where exactly do you guys fill it up to when not overfilling? And when you overfill than you go above the 2nd notch?

It's been a while since i've overfilled, but I believe I used to go right below the 1st number in the part number. I think it's about half a quart. Let some other guys confirm that, as it's been a while. I did it more by just overfilling by about 1/2q, as opposed to trusting the dipstick.

FWIW, whatever difference you see on the dipstick is the amount that the oil level is being raised by in the sump.

To put some quick and dirty numbers to it, figure the sump is roughly 12"x18" (i'm just taking a wild guess). A quick look at an online volume calculator using those rough dimensions tells me this.

6.9q (normal fill) = ~47 mm oil depth
7.6q (1/2 Q over) = ~52 mm oil depth

You're raising the oil depth around the pickup tube by about 5mm by overfilling 1/2q (you can confirm this by dumping an extra 1/2 q in and measuring the difference you see on the dipstick).

If you're concerned with oil starvation, I think an oil pan baffle kit will do a lot more to keep oil around the pickup tube.

Hope that helps.

I get what your saying. But isn't 6.9 + .5 quart 7.4, not 7.6... and I wonder why my 3.2L manual is different from yours.. anyone else want to comment what theirs says?
