I understand that engine oil in an open container or sitting inside of an inactive engine for a year or so, should be changed....But what about seales, unopened and "new" bottles of oil that are a few years old?
I have several 5 quart jugs of synthetic Mobil 1 for my vehicles. They are about 18 months old. Tecently,a self proclaimed oil expert told me that I should not use it.
O disagree. But to be honest, I'm now a little worried.
I never gave fresh, new, sealed bottles of oil a second thought.
