Oil question

["Alan Seigrist Blue 100" <healey.nut@gmail.com>]

Hi -

I have several unopened quarts of Castrol GTX 20W50 that have been on
the shelf about 5 years.

Yesterday I opened one to satisfy my thirst ... and after pouring it
into the BJ8 I noticed a layer of semi-solid brown goo on the bottom
of the bottle.

The oil color (that I poured out) was a perfect golden brown color so
I think the oil was fine to use but my questions are

1) Is the goo the additives that have come out of suspension or is it
something else?

2) If the answer to 1 is yes... should I have shaken or mixed it up
first before pouring it into the car?

Thanks,
