Is oil good after 3 years of extreme temperature cycling?

[Ang]

I read that heat in storage can affect the lifespan of new motor oil. I have 1qt bottles in the back of my cars some are now 2 and 3 years old, exposed to extreme hot and cold for all this time. Should I replace it, or is it still good enough to top off a car?

you should be able to use it,as long if sealed from factory, and shake up a bit at room temperature.

Shaking it up at room temperature isn't always an option on the side of the road if my oil was suddenly low. So should I just buy 2 new supertech bottles for $10 and use the oil in the cars for lubricating tools?

They are perfectly fine to use. A shake before use is helpful (no matter the temp if needed) if they aren't subjected to the vibrations of a moving vehicle's trunk or whatnot. The temps they are exposed to is not extreme at all considering it's not at engine temp areas.

Why would it be suddenly low on the side of the road?

Never know. Oil Burning, Oil leak e.t.c. a 1 Quart bottle is small, So i keep one in the car.

Oil gets up to in excess of 200f in your engine all the time. A few months or years in the trunk of your car won't do much to harm it.

It's already passed that few years, which is why I was questioning replacing it.

If that did happen I wouldn't worry about the age of the oil I'm pouring in

Mobil 1's shelf life recommendation is 5 years, just use it in a 2025 oil change.

Well gas stations always have oil and are climate controlled so there is that. In a pinch who cares if it’s a few bucks more.

 

[OilStainedNapkin]

I wouldn’t worry. It’s virgin oil that’s seen some hot or cold days (and it probably already saw these temperatures while it was shipped via semi truck or rail).

Happened to me on a trip in my truck once. It decided to start hemorrhaging a quart of oil every 75 miles out of the head gasket. It got whatever was oil.

I would be very suspect if I were you. Why not send them to me, I will check them out and let you know...

I believe some car brands even came/come with an extra quart in the trunk at purchase. You'll be fine.

What is "extreme temp?"

 

[eljefino]

I've got Maxlife from 2005 (when the Cars movie came out) that's still fine. The bottles are sealed-- what's getting in or out?

 

[02zx9r rev2]

I do the same, always kept a quart in the trunk just because. Thanks for the reminder, need to use that up and refill

Thread 'Does oil really go bad after 1 year if it was previously opened?'

Does oil really go bad after 1 year if it was previously opened? i see online that its 1 year once opened, and 5+ depending on the type if sealed. for example I buy 1qt oil for small engines that need 1/2qt, so from what I've read here id wait 2 years to change the oil since it won't hit the hours, but if the oil is going bad in a year should I just do a change in 1 year to use it up?

Oil is cheap I replace my oil at least yearly.
