Hi Folks,

I must say, one of the best things I've found on any car is the oil level indicator on the Boxster. I love it! Such a simple thing but so very useful. Why they arent fitted to all cars I'll never know.

However I've probably become a little obsessed with it. I've noticed the level varying by up to three segments from one day to the next on ground that a percieve to be fairly level and when the car is cold. (though not the same ground as my driveway is fairly steep)
Is this normal?

Now given that the difference from empty to full on the guage is only 1.5l I suppose the displacement of a fraction of a litre is no big deal, but could anyone tell me where the oil level sensor is? And is the reseviour it sits in deep or wide & shallow? Just so I have some idea of how it should behave.

Cheers guys!

Bob.

my oil level meter thingy is more sensitive than my girlfriend. and like her, if i were you, i wouldn't trust it for she lies.

use the dipstick. i recently overfilled mine cos of the seemingly trustworthy digital readout.

that said, the dipstick ain't all that accurate either.....sorry.

You will always get an accurate reading if you check the electronic indicator immediately after filling up with petrol (as long as the engine is warm, the surface the car's on is flat and the car has been standing for approx 5 mins at least).

Sorry but just too tempting...

You used your dipstick on your girlfriend and overfilled her..!! I like your style (although my girlfriend doesn't have a digital readout..)

I topped mine up recently using the dipstick, then checked the digital gauge, it showed the gauge was bang on the money.
It has been known to drop by one segment from day to day though.............

Despite the consistency of where my car is parked and recent temperatures, my readings still vary massively.

I'm going to replace it with one of these

Why should filling with petrol make any difference to the electronic reading of the oil level?

Not sure what shape the dry sump tank is, but the whole system holds over eight litres of oil. Min to max on the dipstick is just under one litre.
Even if the dipstick is showing minimum, there's still a fair bit of oil in there................

I just assumed that he meant that the car would probably warm if you were stopping for petrol and that petrol forecourts are generally level.

Although that would mean that it would need a sensor on the petrol cap to tell you when it has just been replaced. Actually, that's not so - it could just make sure than an accurate read-out is available for the first start-up after the fuel level has risen significantly.

...I'm sure that's the procedure described in the manual. Will check when I get home - but I distictly remember needing to have filled the petrol tank up first (unrelated to having to warm the engine up properly before checking). Doesn't make sense, I know, but it works!
