My 2017 just hit 22K miles and my butt dyno is telling me my idle and is feeling a bit lumpy(no Cel or anything). Any recommendations on fuel system cleaners?

I dump a bottle of Chevron Techron cleaner in the tank every 3,000 miles. I figure it won’t do much for the intake valves on our DI engines, but it should help keep the injectors clean.

I use the bmw fuel system cleaner which looks like techron (it used to be made by chevron and was labeled with techron, but it no longer has such markings so it may or may not be techron).

I made a short thread about it here: https://f87.bimmerpost.com/forums/sh....php?t=1743422

I used BMW Genuine fuel system cleaner and did not really feel a difference at 31k miles. But it may not have needed it either. I only use Top Tier fuel in my cars which have extra additives. The BMW cleaner is expensive, but BMW is a very technical company, which gives me confidence that the formulation is tested and proven effective. The new smaller bottles may just be some extra concentrated Techron. If you use something else, I'd ensure it has PEA. That is proven to help with DI injector tip cleaning.

When I buy a car, I always run a quality fuel system cleaner through to give things a "fresh start," so to speak.

It's actually a lot cheaper here in Canada vs. techron, so that's why I use it over techron. But I'm not opposed to using either.

So it turns out that BMW is phasing out their old fuel system cleaner - which I believe is relabeled chevron techron (I called my dealer and they told me there was no stock anywhere locally, and that this part number was being phased out), and they are replacing it with their twin power turbo fuel additive. So if anyone in Canada wants to buy a relabeled techron (because you can't buy actual techron in Canada because it is not labeled in French and the labelling laws prohibit this iirc) the only option left seems to be the hyundai fuel system cleaner (which is relabeled techron):

I will be checking if any of my local dealers has this available.
