Leftover oil

humpday · 09-11-2019, 08:49 PM

Hi all,
This might be a dumb question, but this hasn't happened to me before. I usually get quart sized bottles for oil changes, but this time I got 5 quart jugs of Castrol Edge 0W-40. Typically I'd have a half quart or less leftover. I wouldn't care much for it so I just tossed it with the rest of my used oil. But with these huge jugs, I have over 3 quarts left. Seems like a waste to get rid of it. Is there any harm in just storing it then using it for my next oil change? Not sure if condensation or any other issues with long term storage can occur once the cap and seal are broken. Thanks for any advice.

No harm in storing it with a well closed lid, and using it for the next OC, or top offs if you lost the oil-consumption lottery.

Absolutely store it and use it for your next change. Oil doesn't really expire so as long as you put the cap back on you are good to go.

Absolutely agree with other replies.

Although oil is hydroscopic (absorbs moisture), engine temps means this is evaporated quickly once up to temperature...... :-)
