Oil question please
I have been told oil can go bad just sitting on a shelf, it this true ? Not so much the oil but the add 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.

The oil companies state 5 years so I'll bet 25 is it's half life.

From what I've been told oil never loses it's ability to lubricate it simply gets contaminated when being used. That's why the old Bell Telephone vans used to run forever, they didn't change oil but rather the filter & then add enough to replace & it worked for them.

The lab I send my oil to tells me oil doesn’t go bad. I would not be afraid to run it in any gas engine that has NO catalytic converter. CJ4 being a diesel standard may have too much zinc and phosphorus for modern gas engines with catalytic converters. I would consider it in an older car with a catalytic converter as long as you don’t have emission testing.

Do not worry about how long it has been sitting on the shelf. It is appropriate for your application, go ahead and use it. If the bottles are real old it doesn't hurt to give them a good shake first - to re-suspend any additives that may have settled.
CJ-4 oils came out about 10 years ago, and would be fine for your small power equipment.

Thanks guys, I'm sure its fine. I googled the question since I posted this and found some answers, too many some say five years, some say a few if stored right.. I guess the add pack can separate, so mix it back up..
I'll use it as make up oil or mix it with new stuff..

If it’s 15W40 you want to use it in warmer weather in something like that. Some would argue that diesel oil is better because it has a more robust additive package. These additives can ruin modern pollution control systems, primarily the catalytic converter. These additives were in older gas oils but now they keep reducing zinc and phosphorous to the point that it is harming older engines but they won’t tell you that. Golf carts and lawn mowers I don’t see a problem and it may even be better than what’s out there now.grumpy wrote:Safe for a one cyl Kawasaki golf cart engine ? even thou its diesel oil, is that correct ?
It's 10w-30 cj-4 , can't be more that five years old from the looks of the five gallon pail, but I just don't know. it been in a barn so cold/hot for years.. I don't want to use it in the new 50K Kubota but the golf carts and maybe the Kubota RTV's which are old now, 5500 hours.
Hell these Kubotas have been so abused and neglected and still run fine, I could put french fry oil in them and they would still run. Some of them have gone 450 hours on the same oil.. but there happy I came along, I'm getting them all fixed up..

Yes. It is not just "diesel oil", it is actually dual rated (for diesel and gasoline engines). I have been using it in all my power equipment for a long time.grumpy wrote:I would not be afraid to run it in any gas engineCJ-4 oils came out about 10 years ago, and would be fine for your small power equipment.
