checking oil.

[911 turbo newbie]

what is the right way to check your oil, do you do it from cold or after a run?

The computer won't let you do it until the engine has warmed up (try it). Once it has reached a suitable temperature, then you can check it. Good excuse for a drive. []

have always checked after a run, but am always unsure if this was the right way, now i know[]

Interesting thread, I'm a newbie as well and have relied upon the electronic measurement however when I bought the car and checked the oil manually "from cold start on the level" using the dipstick the dealer explained that as its a dry sump you will not get a reading and therefore only the electronic measurement was accurate at this point.

My questions are, why is there a dipstick and secondly how accurate is the electronic measurement and can this be relied upon always?

Thanks.....

Except it's not a dry sump... Not really.
It's a wet sump with scavenge pumps in the camshaft areas, rather than a dry sump with scavenge pumps in the crankcase and a separate oil tank.

Sean! Stop calling John a Dipstick!! []

The Turbo is dry sump, and the level sensor is in the tank. Therefore, the engine oil needs to be up to temperature (engine idling, on flat ground) to get an accurate measurement. There is no dipstick supplied with the Turbo.

The Carrera engines, as Mark says, aren't truly dry sump, so the measurement is taken after the oil has had a chance to drain back to the sump. Hence you can take the level when cold before starting, or when hot after the oil has drained. (Engine off, on flat ground). You are supposed to do it hot, but I always got more consistent readings doing it first thing in the morning.

The level indicator seems to be pretty accurate, and I suspect that's why they didn't fit dipsticks to 987 or 997 cars (plus the cost saving, perhaps).

Thanks Richard, I think I know who the dipstick is and it's probably me..... I must admit I have not checked the dipstick reading since Jan but will tonight when I get home and see what it looks like.

I'm still nervous about the sensor readings, if the car is at a slight angle/tilt when starting the readings on the computer can be all over the place. I suppose that will wear off once I get more confident about the car and how it works.....

Thanks again....
