I have been told oil can go bad just sitting on a shelf, it this true ? Not so much the oil but the ad pack.. I found some CJ-4 oil but don't know how old it is or if its good to use.. any advice?

Also can CJ-4 oil be used in a gas engine? Like an old golf cart?

thanks guys.

No, but some additives can settle out.

Shake the bottle well before pouring.

I would have no problem using 10 year old oil (for example). Give it a shake before use.

If it's a dual rated HDEO with a Sx spec like CJ-4 / SL then you are good to go in a gaser, assuming you don't need a special OEM cert like Dexos or something.

I believe it's John Deere tractor oil,10w-30 I'll have to take a look again but it just said CJ-4 on the front label, I would like to use it in a Kawasaki golf cart engine .. I did not know you could use a diesel oil in a gas engine, not any gas engine of course..

I believe that additives can settle out but I don't think oil "goes bad".
The only problem with older oil is that it doesn't meet the newest specs.
I have used oil that was nearly 20 years old and had very good UOA's....

PS: Proper storage is also important....I wouldn't use oil that was stored in an unheated garage or shed for years...the constant temperature fluctuations can deteriorate the additives.
I once read that 68* is the ideal storage temp. for oil...

Thats what I am wondering, the oil was stored in a barn in Michigan weather, for how long, 5, 6 7 years, I just don't know. thats why I want to use it in an old golf cart, or as make up oil..or maybe mix it with new oil.. at 25%.. hate to waste it..

Just think of your oil pan, in Michigan or Alaska winter weather, sitting at a toasty 68 degree temperature. Must be a creation of Iffy Lube brought to you with the 3k mi sticker.

I'd run John Deere CJ-4 oil in my 2008 F150 and not even blink an eye. That's excellent oil.

How long does it take for the additives to settle out? According to Blackstone once they settle out they can't be put back in.

Yeah, but a golf cart prolly does not need all the additives anyway smile

From the Blackstone Old Oil Test:

RutRoh, I started my truck at 20 degrees last winter, and the oil got to 195. Quite a few starts this summer from 80 to 205 as well. And that pesky piston oiler that sprays the underside of the piston, I bet I get pretty warm quickly in that zone too. Hot, HOTTER, cooled, hot again.. Dang it, I guess I better change it.
To the OP, check for an "S" rating, like SG, SH, SJ, and use it. Oil does not go bad in storage.

A few years ago Ryan Stark at Blackstone bought a bunch of old, unopened oil cans from various places (ebay, etc). I'm talking about cans as old that they dated back to the time when they were foil-lined cardboard canisters with metal tops and you had to pierce the spout into the can! They tested them and actually found out that the additives didn't fall out nearly as badly as most suspected.

Now, the base stock has a lot to do with this. PAOs do a terrible job of holding stuff in suspension, so they actually have some group II blended in them for that very purpose. However, most decently made dino oils will hold stuff quite well. Don't ask me to explain it; I'm not a chemist.

I'm sure there is a practical limit where it's not worth the risk. But oil that is 5-7 years old would not bother me at all.

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money
