Does engine oil ever go out of date?

Would you recon its safe to use or should I bin it... its nearly full too!! would be a shame to chuck it... but if its going to damage the engine I'd rather buy some new stuff!

Shark90 , you say it breaks down , but into what ?

Oil is pretty complicated stuff and with all its chemicals and additives and hydrocarbons etc there's bound to be a chemical reaction in there somewhere. Perhaps if the bottle was brand new then it wouldn't matter so much, I don't know, but gut instinct tells me that it could possibly go "off" just like petrol does.

To be fair however if they fall apart in the bottle over 2 years, you do have to wonder how on earth they survive up to 2 years in an engine in what are much more hostile conditions.

I then mentioned that I might just use the out of date oil in my lawn mower & cheap workshop compressor (neither had had an oil change for 5 years) & they thought that was a good idea.

They answer to that is.. they don't I wouldn't trust two year old oil, infact I hate variable servicing full stop and so do most mechanics (i.e. the ones that know what they're talking about).
They do survive for 2 years in a car as long as the car is driven under the correct conditions.
I've seen plenty of Octy MK I that are on variable service and running over 250k, so it can't be that bad.
