Very interesting and entertaining read - but what is the final verdict? Apparently, from what I can gather, aside from different additives, the oil itself does not "spoil" or go bad in any form or fashion.

Disagree.

As I read those Blackstone links, they tell us almost nothing about oil shelf life, though I might have missed something.

IIRC there's some elemental analysis (which wouldn't be expected to change), and some viscosity data (which might be expected to increase with age due to loss of volatiles and possible oxidative polymerisation) but there's no before and after comparison (the new oil parameters probably aren't available) so its moot.

An (ideally comparative) oxidative and/or thermal stability test, supported by chromatography, would be of interest, but I havn't seen any such data. The guy does an oil change with some of his vintage oil, but there's no follow-up report on how it does in service.

4WIW (very little) I think its unlikely that oil goes off to any significant extent on the shelf, but I havn't seen any evidence to back up this belief.

If anyone has, I'd be interested in the source reference, partly because I've got a lot of old oil, but mostly because I've got a developing online (elsewhere) argument on this topic with a bunch of (other) British arses.

The Buick is 2005 LeSabre. I just put PU in about 900 miles ago. Was thinking of a short OCI on Wifes Tiburon, but it's 2001, and if I read the chart right, SF/CC is for engines before 1990. But mowers wouldn't mind.



Ultra runs for 10000 miles so try to hold out.

I've seen blackstone write on a used oil analysis posted here in this forum that oil has no shelf life.
So considering they wrote it just that plainly I'll accept it as such.

I don't have any problem believing that, (since its intuitively likely anyway) but I'd like to see some evidence, both for my own interest/satisfaction, and to use against the not-so-silent so-you-think-you-know-better-than-the-manufacturer majority.

There must be some out there.

Pennzoil says their oil will be fine in a garage for 5 years. Thats good enough for me.

Not good enough for me, since I have quite a lot of (maybe) 10 year old oil, and it ain't Pennzoil.
