safe to use TWS 10W-60 that's been boxed for 2 years in a garage?

I have 9 liters of oil for my 09 sitting in a box in storage. Bottles are maybe 3 years old. Was debating using it in the car. each bottle is not opened. The label has started to fall off the bottles though. Does oil break down if it's not used? Should I not use this oil and buy new oil? Suggestions guys? I hate to replace it if it's still good due to the cost of the oil alone.
Thanks.

It does break down, but as long as in a temp controlled environment it should be fine.

a garage in south FL perhaps outside the controlled environment?
Its around 80-90 in there most of the year.


then again, on the flip side. I guess a hundred bucks on new oil is better than 23K on a blown engine.
I don't know if I'd be sleeping well with the old oil in the car.

TWS is considered an outdated oil for our cars, if you want to stick to a 10W60 oil, at least go with the Edge Professional version......or M1 0W40 for $60 at Walmart will get you 10 quarts.

The oil will be fine - the only thing is that the additives can settle with time so a really good shake is required before use.

Never heard this before. Do you have a reference, logic?

is it just me or does BMW not list the old TWS anymore and only list the edge professional TWS on their site from the link that was listed above?

The new oil replaces the old oil. Your old oil is still fine to use just as it was when you bought it 3 years ago. Oil doesn't break down sitting around in its original bottles.

The point is, Edge Professional is a more robust and better oil to protect the engine than TWS. It is definitely an upgrade over the old TWS Motorsport.

here's a snippet of the difference, in my book, it's a pretty big difference:

Good post Mr. Sparkles. So that new "edge professional" is the standard for what oil to put into these motors now? Glad you could clear that up

What I meant was, at least IMO, when someone says TWS they are referring to the BMW Castrol 10-60 oil for M cars. I know it has gone through difference iterations of labeling and additives but its always been called TWS in some form or fashion.

So when you speak as if TWS and Edge professional are different oils I think you wrong in the way you are wording it as they are both TWS (its right on the bottle).

The TWS has a API spec rating of SJ/CF, EDGE Professional is SN/CF which is the latest API specification. SN being for PCMO (Passanger Car Motor Oil) and CF is related to the diesel specification. Shelf life is typically 2 years on most oils as the additives tend to separate from the base stock. You cannot, as has also been stated, just "shake the can" to get the additives back in suspension. Doesn't work that way.

Thanks for the good info everyone.
After reading the link to the Blackstone comparison of TWS 10W60 (old) and Edge Professional TWS 10W60 (new). I've concluded they are not the same oil as the contents/formula are different. Also, as mentioned here the additives fall out of suspension from the oil over time. Therefore, I've decided to order what I believe now to be a better oil (edge professional TWS 10W60) from fresh stock and not use my old garage stored ~3 year old oil. I may be crazy, but why risk the engine for 130 bucks?
Cheers,
X

Most synthetic oil providers have agreed to communicate a five year shelf life. I expect that's a very safe shelf life.

OK you got me...assuming you don't think that there is some sort of chemical deterioration going on....why should you not be able to mix back in the additive particles that have fallen out of suspension and collected on the base of the container?
OK so a 10 sec hand job might not be sufficient but a half decent paint shaker would do it.
