When should I carbon clean my engine?

[KDMCozy]

I just bought a 2020 Kia stinger 3.3 T with 48k miles on it. Car seems to run good and be in great shape, however I don’t have any service records for it and there is no catch can installed. My add w1 twin catch can setup is on the way, but my question is should I go ahead and get a walnut blast just to be on the safe side or wait a little longer? Thanks in advance

In the same boat. I got my 19gt used with 30k miles. I’m almost at 50k miles now and probably will get it done then . I would just go head and get it done for peace of mind sake.

From the personal experience, i can say, every 50-60k miles. I dont have catch cans, and change the oil 3 times every 10k miles.
