Just cleaned the MAF sensors and the throttle body.

Ready to clean the valves with a can of spray (CRC if it matters).
Any thoughts on the need to change the oil after this?

Some concern about unburned chemicals making their way into the oil, and compatibility of the chemicals with engine seals and materials of construction.
Since we are again in a very, very low mileage situation - it could easily be many months before the next oil change.

I just changed the oil about 100 miles ago and it's no big deal to wait on the valves, and just do them right before the next change...

I’ve used several different brands of intake cleaner from seafoam, CRC, B12 etc. and have never changed the oil following. Not saying that’s right, just what I’ve done on multiple vehicles. Only time I’ve used a product and changed the oil was when putting seafoam in the crankcase.
