Transfer case -> canister -> Transfer case

Hi,

LONG VERSION: I bought a used car recently and realized that the oil was overfilled. According to the CarFax, an oil change was done in July, so I didn't want to change it. So I bought an oil evacuation pump (Mityvac 7400, which I was planning to buy anyway) to take out the excess. I ended up taking away too much, so I just poured some of the same (used) oil back in the crank case. Now I got to thinking if there is some Chemistry-related issue that I've forgotten about that would make this a bad idea. This was the first use of the Mityvac as far as I can tell, but I suppose there is a small possibility that it was bought and returned (and cleaned very well!)

SHORT VERSION: is it safe to pour used oil from a clean container back into the crank case, or should I just go ahead and change the oil to be safe?

Thanks!

If the Mity-Vac looked clean, I would have used the old oil.

To many people (including myself) over-think things.

As I get older, I try to make things easier, not more complicated.

No worries as long as the container in the Mightyvac was clean. Sleep well now!

Thanks for the reassurance
