^^^ This is true. While I get where Tcoat is coming from, the oil doesn't just drop back into the pan unchanged, but it also isn't going to get completely broken down from fuel and water sitting in it. Fuel and water sitting in there long term can wear the oil down over time while the car sits, but it'd have to be a really long time to really break it down. It's not going to turn it into useless sludge in a year, but in the case of the OP's car, you're basically a low mileage case even with daily driving. Is that due to short trips? If so, the oil probably isn't always getting up to operating temp, and that can eventually cause issues by not burning off the moisture and fuel that gets into the oil. Again, is it going to kill the car in six months or a year? No, but you wouldn't be doing the car any harm changing the oil once every six months
or once a year given your low miles for a year. What you drive in a year I do in less than 6 months, so I'm pretty much bound to change out my oil twice a year because I drive a lot. You could, as cheap insurance, just change out the oil filter at six months, then the oil and the filter after a year's time. The way our filter is oriented you can swap it out easily without making a mess or having to really top up your oil level as you would in other cars. Just the same, changing it out every 6 months, especially if you DIY and keep receipts for your parts for any warranty purposes, is still cheap insurance that you'll always have fresh oil. You could also send samples of your used oil to a place like Blackstone Laboratories and find out how your oil is doing in your low-mileage case. If it's still in good shape after 6 months, you could go longer before having to change it.
Oil doesn't really break down in a year's time unless it's put through some really heavy use, though. You can be sure the jugs you buy in the store weren't bottled yesterday, and probably spend several months just sitting in warehouse storage before they spend another potential several months on store shelves waiting to be bought. In your car they certainly won't last forever, but won't go bad to a dangerous level in a year's time either unless you're doing track days in sandstorms on 120 degree days as a part of that 3,500 miles of driving you do.
