Just do it with your 20k service as it won't make a hill of beans either way .......12 months or 5k give or take is just fine ... My UOA always come back looking great .

Oh yeah? Would love to learn more about them.

good point. I bought this CPO from a dealer and the record showed the oil change was done at the dealership so I just assumed it was fine.

Used car oil changes ...

It was the early 70s when I bought my first van from a fleet sale. 130K miles of non detergent oil. I failed to think about that as I immediately changed the oil, adding a high detergent type. 1,500 miles later the hydraulic lifters plugged and I learned how to do my first engine rebuild.

Later days I not only did an immediate oil change when acquiring used vehicles but another in 500 miles. I know ... Overkill these days. But it goes to peace of mind.

Then again, I no longer buy another used car each month. My last used purchase was the 997.2 in September of 2014. But if / when I buy another, it will get the same treatment.

Regardless of whether you do 6 months/5k, or 1 year, etc...I think getting a UOA with every change is a must with these cars. It's not a big expense and could potentially reveal engine issues earlier than they would otherwise show themselves. Also, selling a car with multiple UOA going back tens of thousands of miles would be a nice record for new owners to see.

Every 5k or twice a year as a summer car (August & just before storage for me.)

As already suggested do a UOA with a TBN will tell you the life expectancy of your oil and potentially give early warning for a failing part. The remaining life algorithm in today's modern cars is a conservative guide.

Its your choice to when and how often you change your oil and other fluids, but IMO and based on conservative recommendations 5k and twice a year is not needed for normal use.

I change my oil every 5000 miles. I do an oil analysis every time and I have found a breakdown of the package around 8000 miles. I tried doing oil changes at like 6000 miles and even 7000 miles, but remembering the mileage I was always over and under wondering which 1000 miles I needed to change it. So much easier to just change it every 5000 miles. It might be a little early, but I am fine with that as it is easier to manage.

4 months to go 2000 miles? I think maybe that fits my last 4 months but I spent 2 of those months in Hawaii and much of the past month dealing with deep snow. As far as the pandemic goes, I've been working from home so have made a point of getting out of the house and driving daily just for mental health. If there's less than an inch of snow, a good set of snow tires works well -- I'd rather be in the P-car with Blizzaks than in my Expedition unless the snow is deep or I'm particularly worried about idiots on the road.

I've put 12k miles on my 911 in just the past 6 months and over 20k since the start of the pandemic. Great for one's mental health in an otherwise very depressing time. "Porsche Therapy" as I've named it.
