Shelf life of engine oil

Does engine oil have a shelf life?

I've got a couple of 4l tubs of Mobil 1 Semi in the basement from about 3 years ago and now that I'm in a TS rather than a V6 I'm going to need to be using them for topping up.
It's 10W40 so is the right stuff.

I have heard that there is a shelf life on oil but I cannot remember what it is.

However If it was 3 years old and unopened I would use it.

Yeah, completely unopened and has been stored either under the stairs (old house) or in the cellar (current house), so hasn't been through any extreme temperature changes or exposed to sunlight etc.

I work in parts at a VW dealer and none of our engine oil has a shelf life (I just checked for you.) its also 10w40 so should be fine! it only seems to be our MTF and ATF oil that has a shelf life attached to it. Hope this helps

I was going to buy some from them, but I went last week and it was £22 for 5 litres.

In the end I bought some Fuchs XTR from Opie (£16 for 5 litres with member discount as well as free postage )

I am not sure if the free postage is still running though, it was delivered on Wednesday.

As above, but give it a good shake.

Cheers

Drat foiled again! So my quart of castrol 'R' dating from about 1961 is now probably useless.: Mind you as it's veggie based maybe it may come in handy as a laxative? OK, yet another completely uncalled for jokie in a serious thread. :

If it is Veggie based, cook some chips in it.

Or simply burn it and take in the lovely smell..

Make sure if you have a can of old oil that it comes out of the container clear (not cloudy) and that there are no lumpy or jelly like bits in it.

We used to put a teaspoonful in the petrol of our old BSAs, Triumphs and Tribsas to get that wonderful smell of 'R". When I raced a Norton Metisse that used R we had to make sure it was really warm so that the bump start at the beginning of the race was a bit easier. Also it did tend to gum up if left during the closed season. If I remember correctly the Wakefield oil company used the abbreviation of castor oil which became Castrol, but that may be a myth. Apparently the rotary engines of WWI used castor oil in a total loss system so that the oil wafted back and caused pilots 'intestinal hurry'.

The 'R' used to be called Wakefield Castrol R, so your suggestion for where the name came from makes sense.

Yep you are all on the right lines.Now I won't clash with Oilman or the other experts if I can avoid it as I'm no expert in anything.

My 'R' days started when I bought X Harold Daniels Norton International, single cylinder 500c.c. bevel gear drive ohc. complete with Brooklands reverse cone megaphone silencer and garden gate frame. And yes it had exposed hairpin valve springs, with exposed valve stems and felt oil seals that sort of just soaked the oil up, the residue running back through drillings in the head, and the rest flew out over my Mike Hailwood boots. So at least they were fully waterproof.

Engine needed a strip down to wash the burnt on lacquer off with methylated spirit periodically. Oh how the Goldie' and Venom singlers envied my flaming exhaust with just 1/2" chicken wire as it's baffles, but they envied my wonderful perfume more than anything as I revved her up. Like armoore says some put a cupful in their fuel tanks to emulate the smell, but the poor old retards had to use Castrol XXL as the preferred lube for their inferior machinery iirc . Only joking Goldie and Venom boy's they were brilliant thumpers too.

Quite a few of the two wheeled grass cutting two stroke boys, (mods on scooters) would add a spot of brake fluid to their fuel tanks to get a similar stink. Dunno what that did to the motors? Probably kept the transfer ports clean?

I really need to get a life now, as my youth was so bl**dy boring! You lucky young things.
