Should I Change Oil Before Or After Storage
The oil may be fine, but information technology'due south going to have water in information technology, which isn't adept.
When I used to store my cars, I would run them once ever few weeks because I wanted to:
- Keep oil on the internals and then they don't rust (I had cars with bandage iron blocks)
- "Bake" out the water in the oil
- keep the charging system upwardly to snuff
- scare any potential critters that idea the exhaust organization would make a overnice home
In your example: I personally would open up the drain plug and let her sit like that for a week. After all, why not? Hotter oil flows meliorate, only there isn't whatever oil left in the engine, it'south all in the pan (Unless the n54 is designed like the Nissan VQ series engine, which likes to keep near a quart in crevices). Letting information technology drain out for a long fourth dimension will make sure you get all of information technology out.
If you are a real oil geek like me, you lot will even pour some "wash oil" in and allow it get every final drop out. I commonly utilise what ever dino oil is on sale for the wash oil...BMW LL-01 approved oils cost too much to exist pouring them down the drain...
If y'all don't change it...you lot could care for it similar you lot're commencement starting an engine...Why? Because there'south currently no oil at all in the head. So yank the ignition system and fuel pump fuse (or simply the fuel pump fuse) and and so attempt to starting time the car. Do this a few times (Giving the starter time to absurd down betwixt attempts). What this will do is spin the engine at a lower-than-idle speed, without whatever heat, and will prime number your oil system, getting the oil to the head. After you exercise that a few times, pop your fuses back in and commencement her up and permit her run at operating temp long enough to boil off the water thats in the oil. I will include one caviat....I am not very experienced with modern German language designed vehicles...More probable you will definitely get CEL lights, but I am not certain if they will go away when you reinsert the fuses for the ignition system and fuel pump. My point is moot if you have a service tool to articulate them though 
As far equally "is the oil still good" -- well even if you bake out the water, the water that was there, along with the small-scale corporeality of fuel dilution that occurs naturally merely from shutting off the automobile, the oil's going to likely be somewhat acidic. I personally think that is why most manufacturers tell you to alter your oil at a mileage OR engagement increment. If my fading retentivity serves me right, nearly manufacturers country to change it at 6 months regardless if y'all've striking the miles or not.
Hope this helps!
