Engine Oil Life?

It's always amazing what you find when you clean out your boat.

I have about 5 or 6 quarts of oil that are well over a year old, some two years old. Still OK to use? Or should I just discard at a local station?

IMHO they're fine. 1-2 years is nothing if still originally sealed. The spares on my boat are 3 years old.

The stuff it was made from lay underground for a million years and not even in a container and it was still OK when it was brought up.

If the container is properly closed to stop other contamination, that oil will still be good long after we're all dead and gone.

Even if it were unsealed, it will keep for decades.
Just keep the water out of it.
Engine oil has no volatile fractions in it, so it will keep.

engine oil if in the original sealed container will last for years, If the bottle and seal have been broken , the oil is only good if clean and free of water

That's great. Thanks all. I now have about 9 oil changes pre-paid.

I wouldn't trust it! Send it to me for proper... er... disposal. Yeah, disposal.
