Hello folks and what is the oldest oil you ever used? I have used some 10 year old oils but nothing older than that. My dad has some drums of EMBLEM 15w40 that's 15+ years old he is using up.
 
I still have some SJ rated synthetic that I'm using up in my older car. It's from 1997 and 1998. No problems.

I still have a few of them also and I did mix with new and it's good to go in my more of a modern cars 1-4 RATIO. Look at virgin oil analises, they're almost identical, appart an API SE (1972 to 1979) having more Zn and P. But what a VOA shows? Not much IMO.

I remembered reading that a long time ago. I might use up a bit of the few qts. I have left in my 88 E-150. Maybe 1 qt, in the 6 qt sump next oil change. Thanks for reminding me.

I'm not going to use it but have a couple quarts of JM Fields dept store oil that's rated MS... Not sure exactly how old it is but probably pre 1969...

And before anyone goes ape, there is only one can pictured...

5-6 years ago in my Cavalier I used SJ-rated Havoline 10W-30 for top-off...I remember that it came out of the bottle a dark caramel colour.

Years ago I borrowed a friends oil-burner of a car, and topped it off with a really, really old bottle of oil....this would have been in the mid-1990's, and the bottle of oil was from the mid-1980's...

haha Texaco SAE 30 HD saves gasoline!
 
A few years ago when my grandfather passed my father and I were cleaning out his barn and we found several quarts of Oilzum 10w40 motor oil and it must have been 40+ years old or more? I asked him if he was going to recycle it and he said "heck no! It's going in my Buick Regal next oil change!" It ran just fine on that old oil.

Well using true BITOG logic, if it's on the can, it must be true...
 
I used a half qt of m1 that was a few years old and had been left in a covey box under the hood of a Yukon. It had a slighty whitish bubbly consistency. Was about a half court shy of a full oc so I dumped it in.was probably oxidized and im sure
