Oil Pressure

[STiG911]

The 997.2 engine design removed the IMS shaft and (I think) most or all of the camshaft chains, reducing moving parts and internal friction.

Insofar as oil pressure is concerned it will be affected by both standing temperature and age.

Newer oil = higher pressure at standstill. Usually 3.5 bar.

Once the oil is warmed through and a bit older, say 3 to 4 months or so, idle pressure will be about 2.5 bar which is fine. The pressure should rise to 4.5 to 5 under acceleration and stay above 4 even at low speeds. Actually, thinking about it, the 2nd gen engines had an electric oil pump for greater efficiency and spins faster or slower according to demand, so this would account for readings unfamiliar to a 997.1 owner such as yourself.

Hi All,

What is the norm for oil pressure for a 997.2 when idle and driving sedately?
She sits around 2 - 2.5 bar and when I put my foot down, increases to 4 - 4.5.
My 997.1 goes to 5 bar under acceleration. I know this is a new engine design which is why I'm asking.
Thanks

This is a common question we get asked from customers who have changed to a 9X7.2 MA1 - it would appear that oil pressure 'displayed' is generally lower, compared to M96/97 engines.

Hi,

Mine sits at around 2bar when idling, but when under load rises. I was on the Autobahn last week several times and it then sits around 4 bar relatively constantly at higher speeds.

Thanks guys, that's put my mind at rest. []

As mentioned earlier it"s the "on demand" electric oil pump at work. Try it, put your foot down at relatively low revs and see how the oil pressure jumps up immediately.

Hi, I have just picked up my first Porsche (997.2) and drove it 400 odd miles from Scotland to London on Monday.

This morning (Friday) when I took the car out to drive approx 7 miles I got a message confirming the Oil is Low.

My question, as a novice is, how much Oil do 997.2 consume and how much Oil should I top it up with?

Any guidance would be most appreciated.

Thank You.

All three we have owned or own haven't used any between services but others report higher usage. From memory I think the Porsche limit in the Owners Manual is 1 litre per 1500 miles max ( which is a lot!)

On the subject of the Owners Manual, that will tell you how to check the oil ( it needs to be up to temperature and on level ground) and how much to add per "block" below the top. Again from memory I think it is a half litre per block. If yours is coming up with a message it may well be off the bottom of the scale. So add a half at a time and recheck. Don't overfill!!

I would have thought the dealer/garage you bought from should have checked the oil level as part of a PDI so it is a bit odd to get this.

The 997 Register Technical section is a good source of information for your car, so always worth looking through the index to see if your topic is covered.

Here's the link to a thread about oil level checking [link=https://www.porscheclubgb.com/forum/tm.aspx?m=830939]https://www.porscheclubgb.com/forum/tm.aspx?m=830939[/link]

Thank You TSCAPTAIN and LANCERLOT. I topped it up 1/2 litre on Friday and then 1/2 litre today (Saturday) as per instructions / handbook and all is now well. I checked the oil level whilst hot and stationary and I am at the top level now (below overfill) - it takes a little getting used to to not be able to do a quick dipstick check.

(It was a private purchase not from the dealer, hence it was not checked/refilled but they sellor did give me a 1 litre bottle of Mobile 1 for top-ups.... COSTCO sell 5 litres for £30 so that will now stay in the car for emergencies)

Thank you again.
