I am considering 2020 TLX A-Spec 4 cyl. It is a CPO car with only 20K miles. The car is 44 month old and seems to be in a great shape.
According to CarFAX, 5 oil changes were done but with a very long intervals between them. Here is the schedule.

Intervals Mileage
4 month - 7,775
2 month - 8,707
22 month - 13,675
15 month - 19, 132
2 month - 20,040

How damaging were those 22 month and then 1 month between oil changes for the engine longevity?

 

It's likely that the car wasn't driven much during the COVID situation - I wouldn't worry too much about the long interval between oil changes, as synthetic oil doesn't degrade with time like the conventional oils.
Mileage interval appears good. I would purchase this car based on what I see here.

 

Between COVID and having another car that is better to drive on long trips, my 2010 TL reach one year last February since the last oil charge. I called the Acura Service Department and they assured me to go by the MID percentages before I needed to change the oil. Just reached 15% this week so I went ahead and changed the oil. The mileage between servicing was less then normal but the time interval was much more this time 17 months).

 

Thanks everyone. I feel much better now.
