Filled her with oil...

Paul Franssen · Paul Franssen's Garage

...drained the old oil, put 8 liters of new Mobil 1 in and that's it. Didn't start the engine (car is wintersleeping on axle stands in the garage).
Question: is any of the oil I put in going into the block? Since the engine has not been started, is it all remaining in the separate oil tank?
Should I start the engine and let it idle, if so, how long?
The car is going to be resting for another 2 months or so, and I would like the engine internals covered with a film of nice new oil...
Thanks...again, board.

Is 8 liters enough? I thought you need put in more like 12 liters with filter change.

Dutchie · 01-04-2005, 11:39 PM

12 liters is the complete system. You never get all the oil out even if you change the filter 8 to 9 liters is the most you can take out the system.

Where from in Slovenia ?

Maybe that is because the owner from who i bought the car, when changing oil, he dismatled oil cooler and then get out oil with air presure. Dont think that this is a good idea.

Right, Dutchie!
And, of course, since I did not have the engine running, I didn't want to risk a (dirty messy sticky) overflow of the separate tank by putting in more than 8 liters. The original intention was to run the engine in spring, and to gradually fill her up to textbook "hot oil dipstick level".
But I still invite answers to the initial question: should I have the engine idle for a while, to pump over some of that oil (or does it flow into the block by gravity?). Or can I forget it and wait till spring, to finalize the oil changing procedure.
Thanks...

sorry for the hijack Paul

i dont want to see Ales (A911) see filling 12 liter after taking the old out. Not sure about the oil on the cylinders Paul our engines are flat so the oil will be sinking down fast i think. Bump it around 16.00 our time i,m sure someone will chime in.

Cheers,

Until you run the engine the new oil will just sit in the tank.

I would change the filter (a must really) and run the engine till it gets nice and hot before switching off for the last time before storage
After all you don't want your bearings and rings and stuff coated in dirty contaminated oil do you?

As far as I know, given a few months, most 911's will have oil seep into the sump from the tank. As far as the bearings and other oil-critical components are concerned, it's not the oil that they sit in all winter (assuming that they have previously seen usage), but how they are started that matters. It's the first minute or two of run time that wears the engine since they oil may not be well destributed to where it is supposed to be.

If your engine has been sitting for a season with no use, I'd strongly recommend that you remove the plugs (or at least disconnect the coil) and turn the engine over on the starter to prime the oil system before starting it. Basically you turn it over building oil pressure until oil pressure reads on the gauge or the oil-pressure light goes out. Once you have done that, you can reinstall the plugs or the coil wire and start the engine knowing that all of the bearing surfaces are supported with the correct oil pressure or volume. Doing this will also evacuate some or all of the oil from the sump back into the tank.

I also beleive the oil will eventually migrate downward into the sump.
Factoid.....normal 13 qt system usually takes 9-10 qts on each refill ( about 3 qts stays behind...this, for a system that has a front oil cooler). If the engine was recently run when you change the oil...you'll find that about 6 qts comes from the oil tank and 3 qts from the sump. however, if you change the oil with the car not having been run lately...you'll find just the opposite...about 3 qts will come from the tank and 6 from the sump......

If you put down front oil cooler and presurize the lines would you get all out?

Paul Franssen · Paul Franssen's Garage

Wil Ferch (hi), the engine had not been run for 2 weeks when I emptied the oil, and -contrary to my expectations- most of the oil came out of the sump (maybe 6 litres) and the balance from the tank (abt. 3 litres).
Since I had put the small drain container under the sump, and the large one under the tank, this caused the small container to be full to the brim, and when I moved it out from under the car...yep...wipe-up time!
Other than that, the oil change went without a hitch, very easy to do...and as a matter of standard procedure, I also changed the oil and air filters.
To say that such easy work can eliminate one in each two maintenance intervals (I do not have the courage to tackle setting the valves...)

Wil Ferch · 01-05-2005, 05:09 AM

Paul:
Your experience in oil change after a 2 week idle period matches what I say....

Was simply hoping to add this statement for others' use and consideration.....
