Too much oil??!?!?!?

[bhduxbury]

mnb -- the OP indicated he has a 987 -- that car takes less oil than a 986 -- according to my 987 manual:

oil change with filter = 7.75 litres (8.19 quarts)
oil change w/o filter (perish the thought of not throwing on a new filter!) = 7.5 litres (7.93 quarts)

btw, following those guidelines with 2 diy oil & filter changes i have never overfilled, or underfilled, and the fill is at the top (3d) "ok" bar (not the "overfill" bar) -- so i don't think there's a tsb on it -- actually, i'd rather be in the 3 "acceptable" bars (and top off from there) than in the overfill bar (who knows how much?) -- and oh, the "checking from the back" thing sounds like bull****************

as for the bars (1 too low, 3 acceptable, 1 too high) in a 987 --

"The difference between the minimum and maximum marks on the (oil level) segment display is approx. 1.2 litres.

Each segment of the display corresponds to approx. 0.4 litre."

0.4 litre = 13.5 fl. oz / 0.423 quarts / 1.69 cups (just over one cup and two-thirds, which is what i would use).




then again, the OP said: "From the look of the meter it is full at all but one bar"

"at all BUT ONE BAR" -- that means all is perfect, from what i can tell.

but it's an example of yet another potential issue (along with cost) that militates in favor of diy oil/filter changes

rock on

Hi,

I agree with you. But remember, this is all the same engine, just the Bore and Stroke Differ, so the capacities remain the same. I agree that it's better to reside in the in-between marks than to try and Top it Up. The in-between is not Low, just not maxxed...

Happy Motoring... Jim'99

"Hi,

Yes, but remember, this is a quasi-dry sump system, it does in fact have a sump pan. In addition to increased drag on the Crank, an overfill situation can lead to the troubles I mentioned earlier...

Happy Mototoring!... Jim'99"

Thanks Jim.

Boy, I think this is lame! If they are going with a QUASI dry sump, it seems to me they should have left the dipstick in there.

Cheez.

that's cool, jim, but your numbers are a full litre (1.06 quarts, iirc) more than mine -- following yours would surely lead to at least an "indicated" overfill on a 987 on the digimeter. oh well.

and again, on another topic, ron's original post says "From the look of the meter it is full at all but one bar" -- not an overfill situation, from where i stand

I too am a new Boxster owner....2001 S 45K miles. I bought the car with less then full maintenance records although by my eye and also that of my new mechanic (not a dealer but a very reputibule specialist recomended by the local Club chapter) in great condition......THese people are good mechanics I can tell....
I told him to have at it and make sure he inspected every thing and did a full oil change with filter. The car is running great and what a blast it is!!!! But like the rest of you if I do the electronic oil check I too have all the bars lit
Not only that but the receipt very detailed bye the bye says 10 quarts of Mobil 1 0W/40 oil and filter.....

Hi,

They are not my numbers, they are from the TSB cited. If Porsche subsequently lowered the recommended Fill capacity, it's quite possible, but news to me...

Just to chime in, just had the 30k on my 99. 10 quarts and I show all bars lit as well...
