Changing the oil
Is it necessary to change oil Every Spring in my Corvette on C3, 350, when I only put under 500 miles on it a year and run it on weekend during the winter months in the garage?
Thanks for any repy

I would think a yearly oil change before storage would be even better by having uncontaminated fresh oil circulated through a new filter. If you waited for 1,000 miles/2 years the amount of moisture built up inside the engine would be harmful EVEN though you run the engine in winter months to keep the gaskets
, rings, lifters, and oil seals lubricated. My .02 cents.

500 mile per year? Change your oil every year or two. You'll still get 25000 miles or 50 years out of the engine before you have any major issues with the internals, maybe. If it were me, once a year before putting it away for the winter.

My routine is to change the oil just before putting it away for the season. Put a dose of Stabil in the tank and drive to the station to to top it off. All the oil passages and cylinder walls get coated with the new uncontaminated oil. I remove the battery, don't start it at all while in storage. Starting it for short warm ups in the garage does more harm than good.

don't worry about it
my 1980 350 L48 has 78k original miles. I rode motorcycles for the first 23 years of ownership and let it sit for years in the garage and pulling it out for a few weeks at a time during the year round. I put about 2k miles on it a year. so for a 5k mile oil change it would be about 3-4 years between changes. i've even put as much as 10k miles on the newer oils between changes with very good results. even now the motor burns clean with very little smoke. some oils tend to burn quart or 2 every 3-4k miles. topping off and letting it go for a few months longer didn't hurt. well used oil is not a waste, good for gophers. it still runs quite well today. IMHO.

I change my oil once a year but don't really have a down season, as I'll drive mine on a clear winter day if the roads are clean. Once a year works out to about every 2500 to 3000 miles for me.

So to the op, stop cranking it during the winter unless you are going to drive it and get it hot. If you drive 50+ miles to get that 500/yr you can probably go more than 12 months. If just short trips, then yes, change it each year.

You can change it just before storage because the oil is not yet contaminated by many miles of combustion byproducts. It will not hurt anything for fresh oil to be stored that way. Do not start it just for the sake of starting it during the winter season.
You can also throw caution to the wind and change it when you feel like it and probably suffer no ill effects.
