I drive a 2014 Kia Rio 1.6l engine with direct injection.

I am at 22000km and considering using this intake cleaning product that gets sprayed into the intake.

http://crcindustries.com/auto/intake-valve-cleaner.php

It contains high concentrations of the detergent Polyether amine.

I just did a fresh oil change though, and I am curious if this could potentially soil or diminish the quality of my oil to any degree.

On the website directions they mention nothing about doing an oil change after, but I want to be completely sure.

Is there any potential for this intake cleaning product to contaminate the oil?

No.

The intake valves sit in the path of the intake air. The only oil it is supposed to see is whatever is routed back to the intake tract via crankcase ventilation, which will be combusted and sent through the exhaust anyway.
