My 05 GT Mustang is going to become my "seldom" driven car. I have always done fully synthetic oil changes ever 3-3.5k miles, which was almost exactly every 6 months for me.
The car will now be driven 1-2k miles per year. I will still continue with full synthetic oil changes but want to know if changing it once per year will be good enough? The car will not sit longer than a month at a time here, as we do not have winter to worry about.
Once a year is more than enough. I only put about 5k miles a year on my C6 Vette but will do a change 2 times a year since i do many WOT runs over 130mph.
Just got the oil changed in my 14 yesterday. Only had like 2000 miles on it. It was changed before I bought it last July. Got thechange oil soon display so I went ahead and changed it, otherwise, I would have waited a little longer.
I change my own oil so I don't mind doing it every 6 months if I needed to. But with synthetic oil it should be fine going a full year, right? I would never go over a full year though, simply due to condensation concerns.

Of course. That was the case all along. You have been overdoing the oil changes from the start.

I sort of disagree on one point......you can never "overdo" oil changes. I understand what you are saying, from a cost standpoint, but clean oil is the lifeblood of an engine, and it can never be too clean.
Sitting is sometimes as hard on an engine as driving it more. Condensation and other contaminates build up (fuel getting past the rings, etc) and acids can form from simple contact with the cast iron block.
All that being said, once a year, under the circumstances the OP outlines, should be fine.
Once a year should be fine, usually I'd change it out before the fall, as old oil that sits tends to tarnish and stain the internals of the engine due to the acids/fuel/etc that wash down into the oil as you use the engine.
I only drive my Mustang ~100 miles/year, and usually before I park it for the long winter's nap, i'll change the oil.
