is using an open jug of oil ok?

[Loris]

I've had an open 5L jug of PP with about 4L left in my garage from about July to November - it's been inside since and always capped.

Is it ok to use this oil in my car? Or would it have absorbed some moisture or something to make it unsafe?

thanks

 

[shrooms]

Nope, use away.

Oh, come on! What gonna happen to it? The engine will trash it for you.

 

[Eddie]

Use it with confidence.

Most quart/liter bottles are not sealed, use open jug without worrying.

I have a running 5 quart jug of "leftover" oil that I routinely use as the extra 1/2 quart I need on some capacities. Nothing abnormal has ever come up in UOA. It's not like oil absorbs water.

good news - thanks!

FWIW, you may want to keep the plastic containers off of concrete floors as some believe that moisture will leach into the contents. I also make sure the cap is sealed and have taken to some mild shaking before use as some believe the additives may settle to the bottom over time.
Just the "OCD" in me.

I've had an open jug of oil for a few years now of spare bottles, left overs from 5 qt jugs, etc. that I use for my father's '93 Saturn that drinks oil.

As long as the bottle is capped, it's fine.

No, it's bad.. send it to me for disposal

Lol this thread reminds me of my neighbor who happily poured some Shell "Fire and Ice" 10w40 in his jeep last summer. SE i think??

It's happily purring away.. for now. That PP will be as good as new.

Motor oil is not like brake fluid -- it does not readily absorb water from the atmosphere.

so is that why you shouldnt put a car battery on bare cement, or is that something completely different?

 

[Silver_civic]

Completely different my friend.

I used oil that I had (unopened) in my (heated) garage from 1995 until now without problems so I wouldn't worry about a few months.

Leaving a battery on a concrete floor will not discharge it. Likewise, leaving a plastic oil container on your basement/garage floor will not allow moisture to leach in.

Storing that oil for that short of time under those conditions, use it.

When I worked in plants where we had bulk oil, in some cases out in uncontrolled environments, we would send samples for checks every 5 years because of shelf life requirements. It was usually still good unless someone didn't close the fill port letting contaminates in.

"Leaving a battery on a concrete floor will not discharge it. Likewise, leaving a plastic oil container on your basement/garage floor will not allow moisture to leach in."

When car battery cases used to be made out of hard rubber, tiny cracks could let the electrolyte solution interact with the concrete and cause them to discharge. Modern batteries with their composite cases do not have that problem.
