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.
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?
