OFFICIAL OIL THREAD (Trying to clean up all these useless oil threads)

It will be ok, but I would not let it go for very long. Oil that sits for a long time can degrade over time. At the end of the day, treat your Z right.......get the oil changed. Frequent Oil Changes is the one thing you can do to lengthen motor life.

You can never go wrong by changing your oil.

BTW, I too store my care for the winter. I change the oil before storage and change it again soon after I take it out of storage.

Ok I will drive it for a week then change it thanks.

btw 5k miles would normally be a good time to change the oil with redline correct ?

If you go 5k watch the dipstick....my car liked to drink any 5w-30 I put in it(still within nissan parameters on a new block), using 5w-40 rotella now, using very little in comparision.

Oil doesn't break down over time in storage, but condensation does accumulate. You can change your oil in the spring to get rid of that little bit of water, or you can drive it to boil it off. Personally, I wouldn't bother with changing it. The reason to change oil is if and when acids and combustion byproducts accumulate, or if the additives break down from shear. That's a function of use, not time.

I completely agree.

Every oil company I have talked to about their fully synthetic says that there really isn't a shelf life, and that it will last years.
Even when I asked about it sitting in the engine, they said it doesn't matter.


And I agree that if condensation built up. Just drive it for a while, get the oil hot, and bye bye condensation!

Oil does have an "expiration date" - the oil breaks down over time. Plus there is a good chance that you have some condensation in the engine, especially if it is stored where the temperature fluctuates. Personally, I'd change the oil/filter before starting the car after a long storage period (> 3-4 months).

When in doubt, change it. You can't change oil/filter too often.
