Unused, unopened and stored in its original container out of extremes of temperature, motor oil will last for an “extended period”. They then go on to suggest that the oil shouldn’t be used after a few years; the exact period varying between 2 years (according to Total) up to 5 years (Mobil).
Can I use engine oil for 2 years?
Simply put, as a general rule, manufacturers recommend that you change the oil for a gasoline engine every 10,000 to 15,000 km, or about once a year for “regular” usage (frequent but not intensive) or once every 2 years if used less frequently.
How many years can engine oil last?
Well, the oil mostly comes with a five-year shelf life. All the same, if your oil container indicates a shelf-life less than five years, you should work with the printed dates. After the longevity period is over, it is most likely that the synthetic additives in the oil will no longer be efficient.
What happens if you don’t change your oil for 2 years?
Complete Engine Failure – If you go long enough without an oil change, it could cost you a car. Once the motor oil becomes sludge, it no longer removes heat from the engine. This can lead to a complete engine shutdown that will require a brand new engine – or a new ride – to fix.

A modern car rated for 7500 miles per oil change or 1 year should be perfectly fine for 4000 miles or two years… this is exponential decay in action. The point at which the fluid becomes practically worthless should be LONGER than its shelf-life, and that number is needed to estimate the decay rate.
How long can you go past your oil change?
Cars can generally go 5,000 to 7,500 miles before needing an oil change. Furthermore, if your vehicle uses synthetic oil, you can drive 10,000 or even 15,000 miles between oil changes.
