basically i want to know the following

what will be my oil capacity total with the UIDS?
What do you estimate will be the oil change amount? 9.75?
Which dipstick do recommend with the UIDS and the 996.2 motor after 662 11796 so i can read it correctly?
and lastly what do you estimate the 996.2 motor after 662 11796 will show on the electronic oil check at the correct level?

again skip sorry for the confusion answering work calls and emails while trying to explain things on a forum is probably not a good thing to do at the same time.

I would recommend anyone with UAOS w/XTDD on a 996.2 after eng # 662 11796 to change to the 996.1 "54" dipstick. And use the dipstick for reference not the dash gauge.

With the UIDS and "54" dipstick on any m96/01/02/03/04/05 the oil change capacity will be 10.3 Qts ( there is still about 2 addition qts oil in the engine that cannot be drained out), and it will read full on the dipstick.

Also with UAOS w/XTDD you can run from 1/2qt to 1.5 qt "overfull" on the dipstick ( for Track Events depending on eng condition). Ignore the dash gauge as it will read overfull.

perfect … I will order the 54” now and will be waiting patiently for the 1st edition of the UIDS to ship..

Jason has a great picture of the oil amounts taped somewhere on his engine as a reminder. If he sees this, maybe he can post the picture. It's a good idea.

Smart move !! The "55" dipstick ( and lowered oil level) should have never been done. The engineers at Porsche should have their butts kicked.......lol

So that means those of us with 996.1 cars have the correct dipstick already, so we're good to go?

Skip, can you rountinely "overfill" and does that cause any issue, or just for a track day and then go back down to the "prescirbed" max?

Just curious if you got my PM

Hi Matt, yes, 996.1 cars have the "best" (part # 54) dipstick already, so they are good to go.

With the UAOS w/XTDD you "can" overfill all the time and no issues, but, oil is also a consumable just like gas, and with the gas prices I usually just round off to $50 bucks gas at a time, just to make it simple/easy, and I keep my oil "full" all the time and only "over-full" when I know I going to Track it in high heat..( I also keep a watch on oil temp and pressure).

I forgot to answer your PM I was dealing with an investigator over a robbery...lol sorry, I'll get to it..

So, on one hand, Jake recommends to run the oil halfway up the dipstick cold, not higher. But you're saying this is a bad idea on the track. Is it just the UAOS that makes it OK to run a higher oil level?

De Jeeper

Yes the uaos fixes the issue BUT WITH the drain back tube option.

GC996

Seems to me that the UAOS with track drainback is a no brainer for the track and for those that just street their car. You never have to worry about accidently overfilling your oil. The UAOS can handle it.

The factory AOS and the Porsche Motorsports AOS cannot.

I ordered my 54 dipstick last week. Should have it this week. Looking forward to running more oil.

That suggestion first came from Porsche back in about 2001 when customers were complaining of "Smoke Bombs" at DE Events on 996's and Boxsters, and spread through the Porsche Community as way to eliminate the problem. This is way before I invented the UAOS. You really need to know ALL the history behind to fully understand.

The M96 was first designed to hold 9.3qts oil ,then from the DE Events customers were complaining of "Smoke Bombs" so Porsche advised to solve the issue by running 1/2qt low (8.75qts).or half full on the dipstick in 2001, then in mid 2002 Porsche changed the owners manual to indicate the oil change fil capacity was only 8.75qts and the engines had a longer dipstick ( #55) and a revised cluster program... This also meant that people who were running 1/2 low or only half way full on the dipstick were now running only 8.25qts oil. Then there were more instances of rod bearing failures on 996.2 cars because they were running 1 qt low at the track..So that's why I say it's a big NO NO...Of course with a 2 qt deep sump on a 996.2 car, even if you are running at "half full" on the "55" dipstick, you are actually still 1qt more than the original m96 design.

With the UAOS w/XTDD you can run "FULL" even with the original "54" dipstick, and even "overfull"..if you wish..

Oil is the lifeblood of the engine, more is good. The reasons you DON"T want too much is as follows
1 you don't want it to get in the intake
2 you don't want it to hit the bottom of the crankshaft and loose horsepower or get aerated
3 you don't want it to leak/spill out of the top
4 you don't want to carry extra weight or pay extra expense
Number 4 really doesn't count to us Porsche 996 people

This subject belongs in the UAOS thread. BTW there are 8 new versions/variations of the UAOS availible for 986 987 997... !!!

If it is anything like the UAOS, damn the economy, I am looking forward to another issue being solved. As an almost octogenarian I plan on driving....that is driving safely right up until I get my wings......continue to Purge Skip......

frederik

Thanks for the explanation, it all makes sense now and I learned a thing or two. 🙂

Porschetech3

I will continue , problem solving on vehicles is all I have ever done and all I do..I enjoy the designing part best, the rest not so much..

Your welcome !! and it's free of charge..some days I enjoy teaching, others I wish I had a 1-900 line at $3 a minute...
