Once a year or many more miles than that, whatever comes first. So once a year...

Just change the filter and top off what was in the filter. The filter traps all the metal shavings. Also get a magnet for the bottom of the filter you will be surprised what that will pull out of the oil. If you see heavy metal particles change all the oil. Use only GM filters they are the best. Shine a led lite into the waste oil and you should see suspended particles the filter trapped.

I put around 1,500 miles a year--Mobil 1 5-30--Blacksone Labs told me this-- "We dont look at time--we look at miles--oil sitting in the pan does not cause any harm--at 1,500 miles you have lots of oil life left"

If your using synthetic oil--your good for at least 6,000 miles--if you dont drive on dusty roads air filter should lastt a few years --why do oil companys say at least once a year--sell more oil--ill go by what Blackstone Labs say about oil-

You could send the oil to Blackstone labs for analysis. They'll give you an idea of how the oil is holding up.
Personally, given how cheap an oil change is, I'd say once a year is fine.
I use my Corvette for some HPDE events and typically change the oil before every event, even if it's very low miles. Overkill no doubt, but I can buy a lot of oil changes compared to what my engine build cost me.

500 mile oil does have lots of life left, and it certainly won't go bad or cause harm to the engine while sitting in indoor storage. You can keep running it for years without damaging anything. Oil may be cheap, but throwing out multiple oil changes of what is essentially new oil is still wasteful.

I feel bad after two or three years of leaving the oil in my antique cars so I change it but at 500 miles a year i suppose you could go longer. these cars dont have the gasoline washing down the cylinder walls from flooding them so the oil doesn't get contaminated so easily.
on my corvettes I do it annually during the winter nap
i worked for a farmer one summer and he only used the used oil from a local gas station in his farm trucks....they used so much oil it was his way of saving $$ and this was in the late 70s and there was no synthetic oil in common use.

I'm in the low mileage club when it comes to my 02. Even with low miles, I change the oil every year before I put into winter storage.
With my 99, I change it when the DIC tells me to or at 6,000 miles, whatever comes first.
P.S. The GM filters are NOT "the best"

I change the oil in my truck (LQ4) every ~6,000. GM filters are not the best but far from the worst.
