So I recently came across an article that said motor oil which has been opened is only good for 3 months. Motor oil that is unopened is good 2 to 5 years.

I know they recommend changing oil every 3K miles or 3 months (whichever comes first) but I didn't realize it was due to expiration. And I have a lot of unopened oil that is several years old that I buy at the parts store when it's on sale that I plan on someday using in my truck. But this 2 to 5 years crap now has me a bit concerned.

Curious what the opinions of this are.


Also, my truck is not my DD. I've had it close to a year and have not yet put 1K on it. I changed ALL fluids when I purchased it. I'm wondering if it's worth changing the oil and filter now that I'm approaching 1 year even though the mileage on the oil is still very low.
